Question

Auxin is used by gardeners to prepare weed-free lawns. But no damage is caused to grass as auxin.

Options

• Does not affect mature monocotyledonous plants.

• Can help in cell division in grasses, to produce growth.

• Promotes apical dominance.

• Promotes abscission of mature leaves only.

Answer 1

Does not affect mature monocotyledonous plants.

Explanation:

Mature monocotyledonous plants, such as grasses, are unaffected by auxin. Because of their distinct vascular systems and development patterns, monocots, like grasses, are less susceptible to auxin. Consequently, mature monocot plants like grasses are not much affected by auxin.
