Vinay has kept a small herbaceous plant in a test tube containing water. The surface of the water is covered by a layer of oil. After three hours, he observed that the level of water in the test tube has decreased. This is due to:

1. Absorption
2. Transpiration
3. Wilting
4. Both (1) and (2)

Root hairs are the epidermal outgrowths of the outermost layer of roots. They are well-suited for absorption of water from soil due to which of the following features ?

P. Large surface area.
Q. Lower concentration of cell sap.
R. Semi permeable nature of the cell membrane.

1. Only P
2. Only Q
3. Only P and Q
4. Only P and R

Assertion (A): The food prepared by leaves is transported to all parts of the plant.

Reason (R): Roots are the underground parts of the plant which absorb food material from the soil.

1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true but R is not the correct explanation of A.
3. A is true but R is false.
4. A is false but R is true.

Assertion (A): In plants, transportation of water from roots to leaves is carried out by the conducting tissue called phloem.

Reason (R): Roots absorb water and minerals from the soil which are transported to leaves for various metabolic activities like photosynthesis, transpiration, respiration, etc.

1. Both A and R are true and R is the correct explanation of A.
2. Both A and R are true but R is not the correct explanation of A.
3. A is true but R is false.
4. A is false but R is true.
