Question

In higher plants, which structure serve as means to tide over a period of stress and also helping in dispersal

• A. Seed
• B. Both A and B
• C. Spores
• D. Vegetative reproductive structures/ propagules

Answer 1

The correct option is B Both A and B

Seeds

• Seed contains the future plant which upon germination gives rise to a new plant. In higher plants, seeds enter into a state of dormancy during stressful conditions.
• During this phase, they undergo a reduction in metabolic activities and are unable to germinate.
• They resume germination on the onset of favourable growth conditions.

Vegetative structures

• Vegetative structures are vegetative plant parts like the stem, roots, leaves which are used in plant propagation.
• These vegetative propagules help in tiding over stressful conditions and help in perenation.

Final answer:
(c) Both A and B
