Correct answer Carries: 4.

Wrong Answer Carries: -1.

Which type of root system is commonly found in monocot plants?

Tap root system
Fibrous root system
Adventitious root system
Both B and C
4

Monocots typically have a fibrous root system, but some may develop adventitious roots.

Which part of the root helps in the absorption of water and minerals?

Root cap
Region of elongation
Root hairs
Pericycle
3

Root hairs are delicate, thread-like structures that absorb water and minerals from the soil.

Which part of a plant is responsible for the conduction of water and minerals?

Phloem
Xylem
Cortex
Epidermis
2

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

Which of the following statements about root modification is correct?

Pneumatophores are found in desert plants
Prop roots provide support in maize
Taproots are present in monocot plants
Fibrous roots arise from the radicle
2

Prop roots arise from the branches and provide additional support, as seen in maize and banyan trees.

Which of the following statements about the stem is incorrect?

The stem bears leaves, flowers, and fruits
Stems cannot perform photosynthesis
Underground stems of ginger store food
Stem tendrils help plants climb
2

Some stems, such as in Opuntia, are modified for photosynthesis, making the statement incorrect.

Which of the following statements about leaf modifications is correct?

Leaf spines reduce transpiration in desert plants
Tendrils in pea plants are modified stems
Bulbils in onion are modified leaves
Leaves do not store food
1

In desert plants, leaves are modified into spines to minimize transpiration and conserve water.

Which of the following is an incorrect statement about venation?

Parallel venation is found in monocots
Reticulate venation is found in dicots
Mango leaves show parallel venation
Grass leaves have parallel venation
3

Mango leaves exhibit reticulate venation, which is typical of dicot plants, making this statement incorrect.

Which of the following is NOT a function of the stem?

Support
Photosynthesis
Anchorage
Transport
3

Anchorage is a function of the root, while the stem provides support, transport, and sometimes photosynthesis.

Which type of leaf venation is commonly found in dicot plants?

Parallel venation
Reticulate venation
Both A and B
None of the above
2

Dicot plants typically have reticulate venation, where veins form a network.

What is the primary function of the leaf?

Absorption
Photosynthesis
Transport
Anchorage
2

The primary function of a leaf is photosynthesis, which helps in the synthesis of food.
