When food supply is poor, the rate of growth is
1 fast
2 slow
3 intermediate
4 nil
Explanation:
B When food supply is poor, the rate of growth is slow. Lag phase is a process that explain the event of growth rate. Lag phase is the slower phase where cell division is slow. It is also called as period of initial adjustment.

The response of plants to light was first of all discovered by:
1 Lamarck
2 Darwin
3 Thimann
4 Went
Explanation:
B The response of plants to light was first of all discovered by 'Darwin'. The response of plants to light is caused due to a chemical process that is called auxin. Auxin was first discovered for its ability to promote growth in plants. This theory was published in 1880 , in a book 'The Power of Plant Movement'.

Klinostat is employed in the study of
1 osmosis
2 growth movements
3 photosynthesis
4 respiration
Explanation:
B Klinostat is employed in the study of growth movements. A Klinostat is a device which uses rotation to negate the effect of gravitational pull on plant growth and development.

Gibberellic acid induces flowering
1 in short day plants under long day conditions
2 in day-neutral plants under dark conditions
3 in some gymnospermic plants only
4 in long day plants under short day conditions
Explanation:
D Gibberellic acid induces flowering in long day plants under short day conditions.Gibberellic acid, a plant hormone stimulating plant growth and development, is a tetracyclic diterpenoid compound.

The movement of auxin is largely
1 centripetal
2 basipetal
3 acropetal
4 both (a) and (c)
Explanation:
B Auxin is a growth promoting phytohormone. It moves mainly from the apical to the basal end (basipetally). This type of unidirectional transport is termed polar transport. Auxin is the only plant growth hormone known to be transported polarly.
