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.

Assertion (A): The movement of molecules from their lower concentration to a higher concentration requires energy in the form of ATP.

Reason (R): Active transport is the process during which root hairs of a plant absorb minerals from the soil.

1. Both A and R are true.
2. Both A and R are false.
3. A is true and R is false.
4. A is false and R is true.

Assertion (A): Plants absorb water from the soil through a semi permeable membrane. The process is termed as osmosis.

Reason (R): The outermost layer of root hair cell is the cell wall which is semi permeable in nature, so it helps in the process of osmosis.

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.
