Which of the following statements about trichomes is correct?

Trichomes are found on roots and help in absorption.
Trichomes help in reducing water loss from aerial parts.
Trichomes are present in xylem and help in conduction.
Trichomes are involved in transport of organic nutrients.
2

Trichomes are epidermal outgrowths that help in reducing transpiration and protecting the plant from herbivores.

Which of the following is the main function of the epidermis in plants?

Conduction of food
Mechanical support
Protection and water conservation
Photosynthesis
3

The epidermis forms the outermost protective layer of the plant body and prevents excessive water loss.

What is the main function of trichomes in the shoot system?

Water absorption
Reduction of water loss
Nutrient storage
Gas exchange
2

Trichomes reduce water loss by minimizing transpiration and can also provide protection.

Which of the following statements about sclerenchyma is correct?

Sclerenchyma cells have thick lignified walls and provide mechanical support.
Sclerenchyma cells remain alive at maturity.
Sclerenchyma is mainly responsible for photosynthesis.
Sclerenchyma has thin primary walls with intercellular spaces.
1

Sclerenchyma consists of dead cells with thick lignified walls, providing mechanical support to the plant.

What is the function of bundle sheath cells in vascular bundles?

Water absorption
Mechanical support
Regulation of water loss
Storage of starch
2

Bundle sheath cells in vascular bundles provide mechanical support to vascular tissues.

Which of the following statements about the epidermis in plants is correct?

The epidermis is a single layer of cells that provides protection.
The epidermis consists of loosely packed cells with large intercellular spaces.
The epidermis is mainly responsible for transport of water and nutrients.
The epidermis in leaves lacks stomata.
1

The epidermis is a protective layer made of closely packed cells, which reduces water loss and protects internal tissues.

Which of the following statements about xylem is incorrect?

Xylem transports water and minerals from roots to shoots.
Tracheids and vessels are the conducting elements of xylem.
Xylem fibers are responsible for conduction.
Xylem is a complex tissue composed of different cell types.
3

Xylem fibers provide mechanical support, while conduction of water is performed by tracheids and vessels.

Which of the following statements about the hypodermis in monocot stems is incorrect?

It consists of collenchymatous cells.
It provides mechanical strength.
It is present just below the epidermis.
It consists of sclerenchymatous cells.
1

The hypodermis in monocot stems is made of sclerenchyma, whereas in dicot stems, it is made of collenchyma.

What is the primary function of the endodermis in roots?

Storage of food
Prevention of passive water flow
Photosynthesis
Formation of secondary tissues
2

The endodermis has Casparian strips, which regulate the movement of water and minerals into the vascular tissue.

Which of the following plant tissues is responsible for the transport of food?

Xylem
Phloem
Sclerenchyma
Collenchyma
2

Phloem is responsible for transporting organic nutrients, primarily sucrose, from source to sink in plants.
