Question

Which of the following is not a part of the rapid movement?

• A. Sudden propulsion of spores
• B. Creep
• C. Explosive spore dispersal
• D. None of the above

Answer 1

The correct option is B

Creep

The correct option is B.

Explanation of correct option:

1. The movement, which takes place over a very short period, that is, generally under one second is known as the rapid movement.
2. Creep is not an illustration of rapid movement.
3. In geographical terms, creep refers to a slow downward movement of the particles, which takes place on every slope covered with a weathered and loose substance.
4. It is the slow and usually the unnoticeable downslope movement of slope or other debris.

Explanation of incorrect options:

Option A:

1. The movement in plant structures, which takes place over a very short time duration is known as rapid plant movement.
2. The sudden propulsion of spores via the rapid opening of the flower instigated by insect pollination is an illustration of rapid plant movements.

Option C:

1. Explosive dispersal of spores by fungus-like Pilobolus is an example of rapid movement.

Final answer: Creep is not a part of rapid movement.
