Question

Explain the movement in pea plant due to growth ????​

Answer 1

Answer:

Some plants like the pea plant climb up other plants or fences by means of tendrils. ... This causes the tendril to circle around the object and thus clinge to it. More commonly plants respond to stimuli slowly by growing in a particular direction. Because this growth is directional it appears as if the plant is moving.

Answer 2

The answer is as follows;

• Plants such as pea climb up other plants, stem or another object by the means of tendrils.
• These are specialised stem, petiole or leaf used for climbing to support and attachment.
• Tendrils respond to external factors by curling, twitching and attaching to appropriate structures.
• In pea plant, these structures contain sensitive cells in the cell wall initiating thigmotropism.
• Thigmotropism is defined as directional growth of twining plants in response to touch stimuli
• This causes rapid production of auxins opposite to the coiled structure stimulating growth of the structure.
• Since, this development is lateral in direction it appears as if the plant is growing.
