Question

Opening of floral buds into flowers, is a type of?

• A. Autonomic movement of growth
• B. Paratonic movement of growth
• C. Autonomic movement of variation
• D. Autonomic movement of locomotion

Answer 1

The correct option is A

Autonomic movement of growth

The correct option is A:

Explanation for Correct option:

1. An example of an autonomic growth process is the opening of floral buds into blooms.
2. It is an athletic motion.
3. In essence, nastic movement is a non-directional movement that plants exhibit in reaction to environmental factors.
4. The autonomic movements of variation are those that take place in response to external stimuli.

Explanation for Incorrect option:

Option B:

1. When a plant organ is stimulated externally, greater growth occurs on one side and less growth occurs on the opposite side, causing movements of curvature known as tropic and nastic movements.

Option C:

1. Autonomic variation movement: variational movements that take place in the absence of external stimuli.
2. In the Indian Telegraph plant, rhythmic autonomic turgor fluctuations result in the jerky rising and falling of two lateral leaflets.

Option D:

1. The movements of the entire plant or an organ of material within the plant cell that takes place in responses to inherited variables and are free and spontaneous are referred to as autonomic motions of locomotion.
2. For instance, cyclosis, oscillatory movements of oscillators, and zoospore motility

Final answer: The opening of floral buds into flowers is a type of autonomic movement of growth.
