Q.

Xylem in plants are responsible for transport of:

1. water

2. amino acids

3. food

4. oxygen

Q. What is the role of the xylem tissue? What kind of flow can be observed in xylem?

1. Transporting food from leaves to other parts of a plant;material flow is bidirectional
2. Supplying oxygen to different cells of the human bodymaterial flow is allowed for gases only
3. Supplying both food and water to all parts of the plant;material flow is not allowed in xylem
4. Transporting water from root to other parts of a plant;material flow is unidirectional

Q.

Only a few cells of the plant require food.

1. False

2. True

Q. Identify the spindle-shaped cell from the following.

1. Egg cell
2. Nerve cell
3. Muscle cell

Q.

The type of vascular tissue which transports food synthesized in leaves to other parts of the plant is __.

Q.

What is translocation?

Q. Which of the following organ and function is not correctly matched?

1. Small intestine - Nutrients are absorbed into the blood from here
2. Phloem - Transpiration through this element creates a suction pull
3. Kidneys - Filter urea and other toxic materials from the blood
4. Xylem - Conducts water to all parts of the plant body

Q.

Dodder has …………. roots for absorbing nutrients
from the host plant.

1. Tutorial
2. Haustorial
3. Tap
4. Fibrous
