Question

How is geotropism necessary for plant? ​

Answer 1

$\Huge \bf{\red{Answer:-}}$


▶️$\textbf {\underline {GEOTROPISM:-}}$


✅Geotropism is t defines as the upward movement of plants during the growth and downwards by the gravity is known as the Getroprism.


$\textbf {\underline {WHY IT IS NECESSARY FOR PLANT?}}$


✅The geotropism plays the major role in the growth of plants or transferring the energy or other essential things into the all part of plants or its leaves.that's why the Geotropism found in the all plants or trees.

Answer 2

$\huge\bold{Answer}$

$\boxed{\textbf{Geotropism}}$

It is a directional growth movement of curvature in response to force of gravity.

The upward growth of shoots against earth's gravitation represents $\bold{negative\:geotropism}$while the downward growth of roots towards the earth's gravity shows $\bold{positive\:geotropism.}$

●Here, the gravitational force is the stimulus.

●Root cap, nodes, and shoot apex are regions of gravity-perception.

●The zone of elongation in both root and shoot are regions of response.

$\textbf{\underline{Advantages and Necessity}}$

Positive geotropism in roots makes them to grow downwards and penetrate the soil.

This is essential for anchoring plants in the soil and to allow absorption of water and mineral salts from the soil.

Negative geotropism in shoots makes the shoots and their branches to grow vertically upwards.

This raises the leaves and flowers above the ground level.

Because of geotropism:-

● leaves are able to obtain sufficient sunlight and carbon dioxide for photosynthesis.

● flowers are able to attract pollinating agents i.e., insects.

● seeds are easily dispersed by air or by aninlas to far off places.
