Solutions of NCERT for Class 10 Science Chapter 6 Control and Coordination, Topic 6.1 - Animals Nervous System: Page number 105
Q.1. What is the difference between a reflex action and walking?
Answer:
The difference between a reflex action and walking-
REFLEX ACTION
| WALKING
|
Q.2 . What happens at the synapse between two neurons?
Answer:
The synapse is the small space between the two nerve cells. At the synapse, a chemical substance is produced at the end of the axon of one of the neurons that reach the other neurons with the help of dendrite. Therefore, the information signal is transmitted from one neuron to other neurons by synapse.
Q.3. Which part of the brain maintains posture and equilibrium of the body?
Answer:
The cerebellum controls and maintains the posture and equilibrium of the body.
Q.4. How do we detect the smell of an agarbatti (incense stick)?
Answer:
The smell of agarbatti (incense stick) mixed in the air. It is detected by the olfactory receptor of the nose. The sensory nerves of the forebrain send this information to the olfactory lobe and respond to the information signal.
Q.5. What is the role of the brain in reflex action?
Answer:
There is no role of the brain in a reflex action. These involuntary actions are controlled by the spinal cord, which reacts immediately without thinking of how to respond to a stimulus.
Solutions of NCERT for Class 10 Science Chapter 6 Question and Answer, Topic 6.2 - Coordination in plants: Page number 108
Q.1. What are plant hormones?
Answer:
Plant hormones - These are also called phytohormones. Plant hormones are the chemical substance which helps in the growth of the plant(height), flowering and also the development of plants and their response to the environment.
For example; auxins, gibberellins and cytokinins are some phytohormones.
Answer:
Here is the difference:
| Movement of leaves of sensitive plants | Movement of shoot towards light |
| 1. It does not depend on the direction of the stimulus applied. | 1. It depends on the direction of the stimulus applied. |
| 2. The stimulus is touch. | 2. The stimulus is light |
| 3. It is due to the sudden loss of water from the swelling at the base of the leaves. | 3. It is caused by the uneven growth on two sides of the shoot. |
| 4. It is not a growth movement. | 4. It is a growth movement. |
Q.3. Give an example of a plant hormone that promotes growth
Answer:
Auxins are phytohormones that promote the growth in plants.
Q.4. How do auxins promote the growth of a tendril around support?
Answer:
When the tip of the tendril touches support, then the auxin of that side of the tip is moving away from the side of the support. As we know, auxin promotes growth. So, due to the presence of more auxin in it, the side of the tendril away from the support grows longer and faster than the support side. This type of growth, makes the tendrils bend around the support.
Q.5. Design an experiment to demonstrate hydrotropism
Answer:
The movement of the plant in the direction of the stimulus is called tropism.
AIM: To demonstrate hydrotropism in plants.
PROCEDURE :
i. Plant a seedling in a vessel containing soil.
ii. Adjacent to the seedling put a porous pot containing water.
iii. Leave the set up for a few days.
OBSERVATION :
iv. On examining the roots of seedlings it is observed that the roots bend towards the source of water and do not grow straight.
RESULT :
It confirms that the plant shows hydrotropism as the roots bend towards the porous pot of water. Hydrotropism is a plant growth response in which the direction of growth is determined by a stimulus of the gradient in water concentration.
Class 10 Control and Coordination question and answer, Topic 6.3 Hormones in Animals: Page number 111
Q.1 . How does chemical coordination take place in animals?
Answer:
In animals, chemical coordination takes place through the hormones secreted by the endocrine gland. It can also be done by the nervous system, which is called the endocrine system. Endocrine glands secrete hormones directly into the bloodstream that directly reach the specific cells. These cells act according to the information that particular hormones carry.
Q.2. Why is the use of iodized salt advisable?
Answer:
Thyroid glands need iodine to produce the thyroxine hormone which, controls the metabolic activities in our body such as the metabolism of carbohydrates, fats protein etc. Also, due to a lack of thyroxine a disease called goitre is caused.
That's why it advised using iodised salts.
Q.3. How does our body respond when adrenaline is secreted into the blood?
Answer:
The rate of heartbeat becomes faster when adrenaline is secreted into the blood so that the supply of oxygen to our muscles is greater. The amount of blood to the digestive system and skin is reduced because the small arteries around the muscles of these organs contract.
As a result, it turns the direction of blood towards our skeletal muscles. The respiration function becomes faster due to the contraction of the diaphragm and rib muscles.
Q.4. Why are some patients with diabetes treated by giving injections of insulin?
Answer:
Insulin hormone regulates the level of sugars in the blood. If it is not adequately secreted, then the sugar level rises in our blood, causing many harmful effects. So, that is why diabetic patients are treated by giving injections of insulin.
NCERT Solutions for Class 10 Science Chapter 6 Question Answer: Exercise Questions, Page number 112
Solving the Exercise Problem is a good habit, as it makes you more confident and decreases student stress. So, in this, we will cover All NCERT questions with their proper solution.
Q.1. Which of the following is a plant hormone?
(a) Insulin
(b) Thyroxin
(c) Oestrogen
(d) Cytokinin.
Answer:
The correct option is (D)
Plant hormones are auxins, gibberellin, cytokinin etc. Insulin, thyroxine and estrogen are hormones secreted by the human body.
Q.2. The gap between two neurons is called as :
(a) dendrite.
(b) synapse.
(c) axon.
(d) impulse.
Answer:
The correct option is (b)
A small space between the two nerve cells is known as the synapse. It helps in the transmission of an information signal.
Q.3. The brain is responsible for
(a) thinking.
(b) regulating the heartbeat
(c) balancing the body.
(d) all of the above.
Answer:
The function of the brain is; thinking, regulating the heartbeat, and balancing the body. All the voluntary actions are controlled by the different parts of the brain.
So, the correct option is (d)
Answer:
The function of receptors is to detect the information from the environment. These are located in our sensory organs like the eye, ear, skin, nose and tongue. For example, olfactory receptors detect the smell. If these receptors do not work correctly, there will be a delay in getting information from the environment to the brain or spinal cord and due to this, the reaction of the information is also late, which causes harmful effects on our body.
For example,- if skin receptors are damaged, then we cannot get the heat as a stimulus. And if we accidentally touch the hot object, then our hands might get burnt.
Q.5. Draw the structure of a neuron and explain its function.
Answer:
The structure of the nerve cell or neuron-
A neuron is the functional unit of the nervous system. It has three main parts-
- Cell body
- Dendrite
- Axon
The function of nerve cells-
It carries the information in the form of an electrical signal, known as nerve impulses. Cells receive a stimulus to send it to the brain and the spinal cord carries the message from the brain to the target organs.
Q.6. How does phototropism occur in plants?
Answer :
Phototropism is the movement of any part of the plant due to light. Positive phototropism is shown by the shoot of the plant and the root shows negative phototropism. This phenomenon is due to the plant hormone, called auxin.
When light falls on the side of the plant, the auxin hormone shifts towards the other side, which is away from the light. Thus auxin causes growth in the length of the cells in the shady part. As a result, the plant appears to be bent towards the sun.
Q.7. Which signals will get disrupted in case of a spinal cord injury?
Answer:
In the case of spinal cord injury, the following will happen-
- All involuntary actions will be disturbed
- Reflex action will be disturbed because reflexes are located in the spinal cord, and so, the quick response to guard ourselves will not take place.
Q.8. How does chemical coordination occur in plants?
Answer:
Phytohormones or plant hormones are responsible for the chemical coordination in plants.
These hormones regulate the growth of the plants. For example- Auxin can help in the growth of the plant (stem)and Cytokinin is responsible for cell division.
Q.9. What is the need for a system of control and coordination in an organism?
Answer:
For the following function, an organism needs a control and coordination system-
- To save the body of the organism from the changes in the environment.
- Control the speed of voluntary and involuntary action
- the capability of thinking and responding to any external stimuli.
Q.10. How are involuntary actions and reflex actions different from each other?
Answer:
| INVOLUNTARY ACTION 1. Actions that occur immediately without any thinking are known as involuntary actions. 2. Involuntary actions are controlled by the mid-brain and hind-brain. Example breathing, the beating of the heart etc | REFLEX ACTION 1. It is an immediate response to an event which does not require any processing by the brain 2. These activities are controlled by the spinal cord. Example- sneezing, coughing etc. |
Q.11. Compare and contrast nervous and hormonal mechanisms for control and coordination in animals.
Answer:
| NERVOUS MECHANISM | HORMONAL MECHANISM |
|
|
Answer:
| Movement in a sensitive plant | Movement in a human leg |

Question 1:
A plant growth inhibitor hormone that causes wilting of leaves is called.........
(a) Auxin
(b) Cytokinin
(c) Abscisic acid
(d) Gibberellin
Answer:
The correct answer is option(c), Abscisic acid
Question 2:
What is the result of hyperthyroidism in children called?
Answer:
Hyperthyroidism is due to the secretion of excess thyroxine. The most common type of hyperthyroidism in children is called exophthalmic goitre. There is usually a large swelling of the thyroid gland, followed by the bulging of the eyeballs. Hence, this condition is known as exophthalmic goitre.
Question 3:
How do we detect the smell of an agarbatti (incense stick)?
Answer:
Our olfactory organs and receptors help in the detection of the smell of an agarbatti. When the molecules released from the agarbatti are carried by air to the olfactory area, they get dissolved in the mucus. After that, they come in contact with the cilia of the receptor cells, and as a result, a receptor potential develops. Finally, through the olfactory nerve, an impulse reaches the appropriate part of the brain, and the smell of an incense stick is perceived.
Question 4:
Why is abscisic acid known as the stress hormone in plants?
Answer:
Abscisic acid acts on growing systems by inhibiting both cell division and cell extension, interfering with nucleic acid and protein synthesis, stimulating the production of certain hydrolytic enzymes, holding back the use of nutrients, and inhibiting the biosynthesis of various growth hormones. It also causes the closure of stomata and increases the tolerance of plants to various kinds of stresses. Therefore, it is called the stress hormone.
Question 5:
Differentiate between endocrine and exocrine glands?
Answer:
| Endocrine Glands | Exocrine Glands |
| Endocrine glands are those glands which lose all contact with the epithelial surface from which they develop. | Exocrine glands are those that are in contact with the surface from which they develop. |
| They are ductless glands. | They have ducts to carry their secretions. |
| Secrete hormones directly into the blood. | Secretes enzymes or hormones in the specific local areas. |
| Examples- Pituitary, Thyroid, adrenal. | Examples- Salivary glands, sweat glands. |
Question 6:
Mention one function for each of these hormones:
a) Thyroxine
Answer:
Thyroxine is released by the thyroid gland and its main function is to promote the growth and differentiation of body tissues and development of mental abilities.
b) Insulin
Answer:
Insulin is more active in liver, muscles, and adipose tissues. The main function of insulin is it increases the utilisation of glucose in tissues and facilitates the storage of glucose as glycogen in muscles and liver, due to which insulin lowers the blood sugar level.
c) Adrenaline
Answer:
Adrenaline is also known as epinephrine. This hormone is known as the emergency hormone. It increases the heartbeat and provides energy during the fight or flight situation.
d) Testosterone
Answer:
The main hormone of the males is testosterone. It is responsible for the growth of external genitalia and necessary sex organs in the puberty age. It also causes the appearance of secondary sexual characters in males, that is, beard, hair on the chest, linear growth, muscular growth, etc.
e) Growth hormone
Answer:
Growth hormone or somatotropic hormone is the most important hormone for normal growth of the body. This hormone is important because it stimulates retention of proteins and calcium in the body, synthesis and deposition of proteins in the tissues that lead to the growth and elongation of long bones and proper growth.
