Correct answer Carries: 4.

Wrong Answer Carries: -1.

In monocot stems, the vascular bundles are surrounded by which type of supportive tissue?

Parenchyma
Collenchyma
Sclerenchyma
Xylem
3

In monocot stems, each vascular bundle is surrounded by a sheath of sclerenchyma, which provides mechanical support.

Which of the following statements about bulliform cells in monocot leaves is correct?

They are absent in monocot leaves.
They help in leaf rolling under drought conditions.
They are involved in mechanical support.
They regulate photosynthesis.
2

Bulliform cells help in leaf rolling during water stress, reducing water loss in monocot leaves.

Which part of the root stores starch and other nutrients?

Epidermis
Cortex
Pericycle
Endodermis
2

The cortex of roots is responsible for storing starch and other nutrients.

Which cells are responsible for giving strength to vascular bundles in monocot stems?

Xylem parenchyma
Sclerenchymatous bundle sheath
Phloem fibers
Collenchyma cells
2

In monocot stems, each vascular bundle is surrounded by a sclerenchymatous bundle sheath, which provides strength and support.

Which type of ground tissue is responsible for providing mechanical support in young stems?

Parenchyma
Collenchyma
Sclerenchyma
Xylem
2

Collenchyma provides mechanical support to young growing stems and petioles.

Which of the following statements about monocot leaves is incorrect?

Monocot leaves have parallel venation.
Bulliform cells help in leaf rolling during water stress.
Mesophyll in monocot leaves is differentiated into palisade and spongy layers.
Monocot leaves have stomata on both surfaces.
3

In monocot leaves, mesophyll is not differentiated into palisade and spongy parenchyma, unlike dicot leaves.

Which of the following statements about mesophyll in leaves is correct?

Mesophyll is made up of xylem and phloem tissues.
Mesophyll is involved in photosynthesis.
Mesophyll is composed of sclerenchyma.
Mesophyll is absent in leaves.
2

Mesophyll contains chloroplasts and is responsible for photosynthesis in leaves.

Which plant tissue is responsible for the transport of organic nutrients?

Xylem
Phloem
Parenchyma
Collenchyma
2

Phloem is responsible for the transport of organic nutrients, mainly sucrose, from source to sink in plants.

Which of the following statements about dicot and monocot leaves is correct?

Dicot leaves have parallel venation
Monocot leaves have reticulate venation
Dicot leaves have palisade and spongy mesophyll
Monocot leaves have a ring of vascular bundles
3

Dicot leaves have distinct palisade and spongy mesophyll layers, while monocot leaves do not show this differentiation.

Which of the following statements about the ground tissue system is incorrect?

It includes all tissues except epidermis and vascular tissues.
It is mainly composed of parenchyma, collenchyma, and sclerenchyma.
It plays no role in photosynthesis.
Mesophyll in leaves is a part of the ground tissue system.
3

The ground tissue system includes mesophyll, which contains chloroplasts and plays an essential role in photosynthesis.
