Q2. Make a sketch of the human nerve cell. What function do nerve cells perform?
Here is the sketch of the human nerve cell:
Function-
The nerve cell receives and transfers messages, thereby helping to control and coordinate the working of
different parts of the body.
Q3. Write short notes on the following.
(a) Cytoplasm
Cytoplasm -The jelly-like substance between the nucleus and the cell membrane is called cytoplasm. nucleus. Various other components, organelles, of cells are present in the cytoplasm. These are mitochondria, Golgi bodies, ribosomes, etc.
Q3. Write short notes on the following.
(b) Nucleus of a cell
Nucleus of the cell-
It is an important component of the living cell. It is generally spherical and located in the centre of the cell. the nucleus contains thread-like structures called chromosomes. These carry genes and help in inheritance or transfer of characters from the parents to the offspring.
Q4. Which part of the cell contains organelles?
The cytoplasm is the part of the cell that contains organelles like are mitochondria, Golgi bodies, ribosomes, etc.
Q5. Make sketches of animal and plant cells. State three differences between them.
Differences between them-
Plant cell-
Animal Cell-
Q6. State the difference between eukaryotes and prokaryotes.
Eukaryotes -
Prokaryotes -
Q7. Where are chromosomes found in a cell? State their function.
Chromosomes (thread like structure) found inside the nucleus. It plays an important role.
These carry genes and help in inheritance or transfer of characters from the parents to the offspring
Q8. ‘Cells are the basic structural units of living organisms’. Explain.
The cell is the smallest unit of living organisms and is capable of all life functions. These are the building blocks of life. that's why cells are referred to as the 'basic structure and functional unit of life'.
Q9. Explain why chloroplasts are found only in plant cells?
In a plant cell, green coloured plastids are called chloroplasts.
They provide green colour to the leaves.chlorophyll in the chloroplasts of leaves, is essential for photosynthesis. Since photosynthesis can perform by only plants so chloroplast is present in plants.
Q10. Complete the crossword with the help of clues given below.
