Wrong Answer Carries: -1.

Which of the following statements about xylem and phloem is correct?

Xylem transports food, while phloem transports water
Both xylem and phloem conduct water
Xylem conducts water, while phloem conducts organic nutrients
Phloem conducts water, while xylem conducts organic nutrients
3

Xylem transports water and minerals, while phloem transports organic nutrients such as sucrose.

Which tissue in the vascular system is responsible for the transport of water and minerals?

Xylem
Phloem
Parenchyma
Collenchyma
1

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

In which type of plants are vascular bundles found scattered throughout the ground tissue?

Dicot stems
Dicot roots
Monocot stems
Monocot roots
3

In monocot stems, vascular bundles are scattered within the ground tissue and lack cambium.

Which of the following statements about medullary rays in dicot stems is incorrect?

They are made of parenchyma.
They are responsible for lateral conduction of nutrients.
They are absent in dicot stems.
They are present between vascular bundles.
3

Medullary rays are present in dicot stems and play a role in lateral conduction of nutrients.

Which of the following statements about pith in monocot roots is correct?

Pith in monocot roots is well-developed.
Pith in monocot roots is absent.
Pith in monocot roots is composed of sclerenchyma.
Pith in monocot roots functions in photosynthesis.
1

Monocot roots have a well-developed pith, whereas in dicot roots, the pith is either small or absent.

Which type of vascular bundle is found in monocot roots?

Radial, polyarch
Conjoint, open
Collateral, closed
Bicollateral
1

Monocot roots have radial, polyarch vascular bundles, meaning they have multiple xylem bundles arranged radially.

Which of the following statements about tracheids is correct?

Tracheids are living cells involved in conduction.
Tracheids have perforation plates for efficient conduction.
Tracheids provide both mechanical support and water conduction.
Tracheids are found only in phloem.
3

Tracheids are dead cells with thick lignified walls that help in both mechanical support and water conduction.

Which part of the dicot leaf contains chloroplasts and is responsible for photosynthesis?

Epidermis
Mesophyll
Bundle sheath cells
Phloem
2

Mesophyll consists of palisade and spongy parenchyma, both of which contain chloroplasts and perform photosynthesis.

Which vascular tissue transports food in plants?

Xylem
Phloem
Parenchyma
Collenchyma
2

Phloem is responsible for the transport of organic nutrients, particularly sucrose, from the leaves to different parts of the plant.

In which type of vascular bundle are xylem and phloem arranged in an alternate manner along different radii?

Radial
Conjoint
Collateral
Bicollateral
1

In radial vascular bundles, xylem and phloem are arranged alternately, as seen in roots.
