Anatomy of Flowering Plants Chapter-Wise Test 10

Correct answer Carries: 4.

Wrong Answer Carries: -1.

Which part of a plant is composed mainly of simple tissues?

Epidermis
Vascular bundles
Ground tissue
Pericycle
3

The ground tissue consists mostly of simple tissues like parenchyma, collenchyma, and sclerenchyma.

Which of the following statements about the cortex in roots is correct?

The cortex is composed of lignified dead cells.
The cortex helps in water and nutrient storage.
The cortex contains vascular bundles.
The cortex is the innermost layer of the root.
2

The cortex consists of parenchymatous cells and stores water, nutrients, and starch in roots.

Which of the following statements about pericycle in roots is correct?

The pericycle is the innermost layer of the cortex.
The pericycle gives rise to lateral roots.
The pericycle is absent in dicot roots.
The pericycle is made up of xylem and phloem tissues.
2

The pericycle is responsible for the initiation of lateral roots in dicot and monocot roots.

Which layer in dicot roots lies between the epidermis and the vascular bundle?

Endodermis
Pericycle
Cortex
Pith
3

The cortex lies between the epidermis and vascular bundle and consists mainly of parenchymatous cells.

Which of the following statements about stomatal apparatus is correct?

Stomatal pores are surrounded by specialized guard cells.
Guard cells do not contain chloroplasts.
Subsidiary cells are always absent in the stomatal complex.
Stomata are present only in stems and absent in leaves.
1

Stomata are surrounded by specialized guard cells, which regulate the opening and closing of the stomatal pore.

Which of the following statements about endodermis in roots is correct?

Endodermis is the outermost layer of the root.
Endodermis cells contain Casparian strips.
Endodermis is made up of dead cells.
Endodermis stores starch in monocot roots.
2

Endodermis cells contain Casparian strips, which help regulate the movement of water and solutes into the vascular bundle.

Which of the following structures is unique to monocot leaves?

Palisade mesophyll
Spongy mesophyll
Bulliform cells
Bundle sheath cells
3

Bulliform cells in monocot leaves help in minimizing water loss by curling the leaves under drought conditions.

Which vascular tissue component provides structural support in plants?

Sieve tubes
Companion cells
Tracheids
Parenchyma
3

Tracheids are elongated, lignified cells in xylem that provide structural support and facilitate water conduction.

What is the main function of phloem in vascular plants?

Transport of water
Transport of organic nutrients
Mechanical support
Prevention of transpiration
2

Phloem transports organic nutrients like sucrose from the leaves to other parts of the plant.

Which layer in the dicot root prevents water loss and has casparian strips?

Cortex
Pericycle
Endodermis
Epidermis
3

The endodermis contains Casparian strips that prevent the passive movement of water, regulating transport into the vascular tissue.
