• B. All kinds of seeds can be dispersed by wind
• C. Seeds dispersed by wind cannot be dispersed by animals
• D. Some seeds are dispersed by water

Answer 1

Answer: (A), (D)

The correct options are
A Some seeds are dispersed by wind
D Some seeds are dispersed by water

• Seed dispersion is the transport of seeds away from the parent plant. Seed dispersal occurs through various means like through wind, water, animals or by pod explosion, depending upon the type of seeds to be dispersed.
• Only the seeds that are dry and light-weight like dandelion, maple, etc., can be dispersed by wind.
• These seeds dispersed by wind have hair-like structures. So they can stick to the animals and get dispersed when the animals move from one place to another.
• Seeds of plants like coconut, lotus, etc., which have fibrous or spongy coating can float on water while the heavy-weighted ones will sink.
