Correct answer Carries: 4.

Wrong Answer Carries: -1.

Which of the following statements about seeds is correct?

The radicle develops into the root
The plumule gives rise to the root
The cotyledons store food in monocots
Monocot seeds have two cotyledons
1

The radicle develops into the root, while the plumule forms the shoot.

Which type of root modification provides mechanical support in maize and sugarcane?

Tuberous roots
Prop roots
Pneumatophores
Stilt roots
4

Stilt roots arise from lower nodes and provide mechanical support in plants like maize and sugarcane.

Which part of the seed is responsible for providing nourishment to the developing embryo in legumes?

Endosperm
Cotyledons
Scutellum
Plumule
2

In legumes (dicots), the cotyledons store and provide food to the developing embryo.

Which of the following statements about leaves is incorrect?

Simple leaves have an undivided lamina
Compound leaves have multiple leaflets
The petiole connects the leaf to the root
Leaf tendrils in pea help in climbing
3

The petiole connects the leaf to the stem, not the root.

Which part of the embryo gives rise to the shoot system?

Plumule
Radicle
Cotyledons
Endosperm
1

The plumule is the part of the embryo that develops into the shoot system.

Which of the following statements about fruit types is incorrect?

Berry fruits develop from a superior ovary
Drupe fruits have a fleshy mesocarp
Aggregate fruits arise from multiple flowers
Legumes split open at maturity
3

Which of the following terms describes flowers in which the ovary occupies the highest position on the thalamus?

Hypogynous
Perigynous
Epigynous
Half-inferior
1

In hypogynous flowers, such as mustard, the ovary is superior and occupies the highest position on the thalamus.

Which of the following statements about flower symmetry is correct?

Zygomorphic flowers can be divided into two equal halves in multiple planes
Actinomorphic flowers have radial symmetry
Pea flowers exhibit actinomorphic symmetry
Sunflower flowers are zygomorphic
2

Actinomorphic flowers have radial symmetry, meaning they can be divided into equal halves in multiple planes.

Which structure protects the root meristem as it grows through the soil?

Root cap
Root hairs
Pericycle
Endodermis
1

The root cap is a thimble-like structure that protects the root tip from mechanical damage as it grows through the soil.

Which part of a leaf contains the vascular tissue for transport?

Lamina
Stipule
Petiole
Veins
4

Veins in a leaf provide mechanical support and act as channels for the transport of water, minerals, and food.
