Question

give the scientific term of the following :
a) growing of roots towards the gravity .
b) growth independent movement in plants
(I need clear answer then I will mark u as brainalist)​

Answer 1

Answer:

a) Plants respond directly to Earth’s gravitational attraction, and also to light. Stems grow upward, or away from the center of Earth, and towards light. Roots grow downward, or towards the center of Earth, and away from light. These responses to external stimuli are called tropisms. Plants’ growth response to gravity is known as gravitropism; the growth response to light is phototropism. Both tropisms are controlled by plant growth hormones.

b) Growth dependent movements are in response to light, water, chemical stimuli, gravity, etc. ... Growth independent movements are also called nastic movements. iii. Growth independent movements are in response to touch or for capturing prey or liberating the seeds.

hope this will help you :)
