Correct answer Carries: 4.

Wrong Answer Carries: -1.

Which plant tissue is responsible for the transport of water and minerals?

Xylem
Phloem
Collenchyma
Parenchyma
1

Xylem is responsible for the transport of water and minerals from the roots to other parts of the plant.

Which of the following statements about intercalary meristem is incorrect?

Intercalary meristem is found in grasses and bamboo.
Intercalary meristem helps in elongation of internodes.
Intercalary meristem is located at the tip of the root and shoot.
Intercalary meristem is a type of primary meristem.
3

Intercalary meristem is located at the base of leaves and internodes, not at the tips of roots and shoots.

Which tissue system includes the epidermis, stomata, and trichomes?

Vascular tissue system
Ground tissue system
Epidermal tissue system
Meristematic tissue system
3

The epidermal tissue system consists of the epidermis, stomata, and trichomes, which provide protection and regulate gas exchange.

Which of the following tissues provides mechanical support and flexibility?

Parenchyma
Collenchyma
Sclerenchyma
Phloem
2

Collenchyma provides mechanical support while allowing flexibility in young stems and leaves.

Which type of vascular bundle arrangement is present in roots?

Radial
Conjoint
Bicollateral
Scattered
1

In roots, vascular bundles are radial, where xylem and phloem are arranged on different radii.

Which of the following statements about bundle sheath cells is incorrect?

Bundle sheath cells surround vascular bundles.
Bundle sheath cells regulate the movement of substances into and out of vascular tissues.
Bundle sheath cells are present only in monocots.
Bundle sheath cells provide mechanical support.
3

Bundle sheath cells are present in both monocots and dicots, although they are more specialized in C4 plants.

Which of the following statements about dicot leaves is incorrect?

Dicot leaves have reticulate venation.
Dicot leaves have differentiated palisade and spongy mesophyll.
Dicot leaves lack stomata.
Vascular bundles in dicot leaves are arranged in a branching pattern.
3

Dicot leaves have stomata, primarily on the lower epidermis, for gas exchange and transpiration.

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

The epidermis is usually a single layer of cells.
Epidermal cells contain chloroplasts.
The epidermis helps in reducing water loss.
Trichomes are part of the epidermal tissue system.
2

Epidermal cells generally lack chloroplasts, except for guard cells, which regulate stomatal opening.

Which of the following statements about sclerenchyma is correct?

Sclerenchyma cells are living at maturity
Sclerenchyma provides flexibility to plant organs
Sclerenchyma consists of thick-walled, dead cells
Sclerenchyma is involved in photosynthesis
3

Sclerenchyma cells have thick, lignified walls and are dead at maturity, providing mechanical strength to plants.

Which of the following statements about stomata is correct?

Each stoma is surrounded by guard cells.
Stomata are absent in leaves and present only in stems.
The outer walls of guard cells are thick, and the inner walls are thin.
Guard cells lack chloroplasts.
1

Each stoma is surrounded by two guard cells, which regulate its opening and closing. The outer walls are thin, and the inner walls are thick.
