Which of the following absorbs minerals form the soil?

  1. Xylem

  2. Phloem

  3. Root hair

  4. Cambium

Show answer
Correct Option: C
Explanation:

Minerals are absorbed form soil with the help of root hair.

Which of the following structures constitute the vacsular system of plants? (i) Xylem (ii) Stomata (iii) Root hair (iv) Phloem

  1. (i) and (ii)

  2. (ii) and (iii)

  3. (i) and (iv)

  4. (ii) and (iv)

Show answer
Correct Option: C
Explanation:

Xylem and phloem constitute the vascular system of plants.

Which of the following allows uptake of water by root hair through osmosis?

  1. Higher concentration of water molecules in root cells.

  2. Increased surface area of roots by root hairs

  3. Low concentration of water molecules in soil.

  4. Semi permeability of plasma membrane of root hair cells.

Show answer
Correct Option: D
Explanation:

Osmosis occurs across semi permeable membrane. It allows movements of water from soil (high concentration of water) to the root hair (low concentration of water)

Which of the following is TRUE for epiblema?

  1. It is the skin of root which outgrows to form root hair.

  2. It consists of specialized cells that provide flexibility to the stem.

  3. It helps in transportation of minerals and water to leaves.

  4. It is responsible for the process of transpiration.

Show answer
Correct Option: A
Explanation:

Epiblema is the skin of root which outgrows to form root hair.

In which form food is transported in plants?

  1. Glucose

  2. Starch

  3. Cellulose

  4. Glycogen

Show answer
Correct Option: A
Explanation:

Food is transported to different parts of plant in the form of glucose.

Which of the following is true for ascent of sap? (i) Movement of water (ii) Movement of minerals (iii) Absorption of minerals (iv) Absorption of water

  1. (i) and (iv)

  2. (ii) and (iii)

  3. (i) and (ii)

  4. (iii) and (iv)

Show answer
Correct Option: C
Explanation:

Ascent of sap is upward movement of water and minerals. It is not related to absorption of water and minerals.

Which of the following process requires energy for transportation?

  1. Osmosis

  2. Diffusion

  3. Transpiration

  4. Active transport

Show answer
Correct Option: D
Explanation:

Active transport requires plant to expend energy.

Which of the following function is carried out by sieve tubes?

  1. Absorption of food

  2. Absorption of minerals

  3. Transportation of water and minerals

  4. Transportation of food

Show answer
Correct Option: D
Explanation:

Sieve tubes are part of phloem. They transport food from leaves to other parts of the body.

Which process governs uptake of water by root hair?

  1. Active transport

  2. Osmosis

  3. Imbibition

  4. Absorption

Show answer
Correct Option: B
Explanation:

The process of osmosis governs the uptake of water through root hair.

Which of the following processes is responsible for creating a pull that helps in upward movement of water in xylem vessels?

  1. Transpiration

  2. Respiration

  3. Photosynthesis

  4. Osmosis

Show answer
Correct Option: A
Explanation:

Transpiration (loss of water) through stomata creates a pull for upward movement of water in xylem vessels.
