Important Questions of NCERT Class 11 Biology Chapter 6 Anatomy of Flowering Plants

Given below is a question from this chapter, along with the solution. Doing regular practice with these questions will help in gaining clarity. Students can refer to the NCERT Solutions for Class 11 Biology Chapter 6 Anatomy of Flowering Plants for more such questions.

Question 1: Passage cells are thin-walled cells found in

Options

1- Endodermis of roots facilitates the rapid transport of water from the cortex to the pericycle

2- Phloem elements that serve as entry points for substances for transport to other plant parts

3- Testa of seeds to enable the emergence of the growing embryonic axis during seed germination

4- Central region of the style through which the pollen tube grows towards the ovary

Answer:

In roots, the innermost layer of the cortex is known as the endodermis, which is an important regulating layer in the movement of water and nutrients. Some endodermal cells, opposite the xylem patches, are thin-walled and are termed passage cells or transfusion cells. These passage cells can perform direct transfers of water and dissolved salts from the cortex to the xylem, thus allowing direct transport to the vascular system and thence to the pericycle, which then allows for distribution throughout the plant.

Hence, the correct answer is option (1), the endodermis of roots facilitates the rapid transport of water from the cortex to the pericycle.

Question 2: What is the fate of primary xylem in a dicot root showing extensive secondary growth?

Options

1- It is retained in the center of the axis

2- It gets crushed

3- May or may not get crushed

4- It gets surrounded by primary phloem

Answer:

The primary xylem is retained in the center of the axis, while the primary phloem is crushed. In many plants, this arrangement allows the xylem to continue functioning in water and nutrient transport, even as the plant grows. The crushing of the primary phloem enables the plant to develop a secondary phloem, which takes over the function of food transport.

Hence, the correct answer is option (1). It is retained in the center of the axis

Question 3: A plant tissue, when stained, showed the presence of hemicellulose and pectin in the cell wall of its cells. The tissue represents

Options

1- Collenchyma

2- Sclerenchyma

3- Xylem

4- Meristem

Answer:

Collenchyma cells are characterized by the deposition of cellulose, pectin, and hemicellulose in their cell walls, which provides them with flexibility and mechanical support. These cells help in strengthening the growing plant.

Hence, the correct answer is option (1). Collenchyma

Question 4: Which one of the following cell types always divides by anticlinal cell division?

Options

1- fusiform initial cells

2- root cap

3- protoderm

4- phellogen

Answer:

Anticlinal cell division, a type of cell division in which the cells divide perpendicular to the surface, is how protoderm cells proliferate, increasing the plant's surface area. This kind of cell division is different from others, such as periclinal division, which thickens the tissue by dividing cells parallel to the surface.

Hence, the correct answer is option (3). Protoderm

Question 5: In conifers, fibers are likely to be absent in

Options

1- Secondary phloem

2- Secondary Xylem

3- Primary phloem

4- Leaves

Answer:

Elongated cells that are present in sclerenchyma are called fibers. Sclerenchyma is absent in the secondary xylem; hence, there is an absence of fibers as well.

Hence, the correct answer is option (2). Secondary Xylem

Question 6: Which of the following tissues is responsible for the formation of annual rings in woody dicot stems?

Options

1– Vascular cambium

2– Cork cambium

3– Intercalary meristem

4– Apical meristem

Answer:

Annual rings in woody dicot stems are formed due to the activity of the vascular cambium, which produces secondary xylem and secondary phloem. The difference in the growth rate during spring (spring wood) and autumn (autumn wood) creates distinct rings, known as annual rings.

Hence, the correct answer is option (1). Vascular cambium

Question 7: Which component of xylem is mainly involved in the conduction of water in gymnosperms?

Options

1– Vessels

2– Tracheids

3– Xylem fibres

4– Xylem parenchyma

Answer:

Gymnosperms typically lack vessels (except a few like Gnetum). Therefore, the main water-conducting elements in gymnosperms are tracheids.
They are elongated cells with tapering ends and bordered pits, facilitating efficient water conduction.

Hence, the correct answer is option (2). Tracheids

Question 8: Casparian strips are found in which part of the plant?

Options

1– Epidermis of the root

2– Endodermis of the root

3– Cortex of the stem

4– Pericycle of the root

Answer:

Casparian strips are band-like thickening of suberin present in the radial and transverse walls of endodermal cells of roots. They regulate the movement of water and minerals into the vascular tissues by blocking the apoplastic pathway.

Hence, the correct answer is option (2) Endodermis of the root.

Question 9: Which of the following tissues provides mechanical strength to mature plant parts?

Options

1– Parenchyma

2– Collenchyma

3– Sclerenchyma

4– Meristem

Answer:

Sclerenchyma consists of dead cells with thick, lignified cell walls. It provides mechanical support and strength to mature parts of the plant, such as stems, roots, and vascular bundles.

Hence, the correct answer is option (3) Sclerenchyma.
