Question

The upward and downward movement of root and shoot influenced by gravity is called?

Answer 1

Answer:

Tropisms and Nastic Movements

Explanation:

Tropisms are growth responses of plants that result in curvatures of plant organs toward or away from certain stimuli. ... In most plants, roots grow downward with gravity while shoots grow upward against gravity.

Answer 2

The upward and downward movement of root and shoot influenced by gravity is called Geotropism.

About Geotropism:

• A plant's coordinated process of unequal growth in response to gravity tugging on it is known as gravitropism.
• Fungi also experience it.
• Natural gravity or "manufactured gravity" are both forms of gravity.
• It is a characteristic shared by all higher and many lesser plants, in addition to other living things.
• Geotropism is the term for the movement of plant components in response to the direction of gravity.
• As they expand in the direction of gravity, plant roots are an example of geotropism.
• Geotropism is the growth of plant parts in response to gravity, whereas phototropism is the orientation of a plant or other creature in response to light.

• Positive geotropism describes the downward growth of roots while negative geotropism describes the upward growth of plant shoots.

What exactly is sensory in plants?

• Light, gravity, temperature, and physical touch are all detected and responded to by sophisticated systems in plants.
• Receptors detect environmental cues and relay the information to effector systems, which often use intermediate chemical messengers to trigger plant responses.
