DMPQ- What are directional and non-directional movements in plants?

by

Directional Movements Directional changes are called tropic movements. Tropic movements are the one which occurs in the direction of the stimulus. Positive phototropism is responding by bending towards the sunlight which can be seen in shoots. Negative geotropism is growing away from the ground which is also shown by shoots. Roots exhibit negative photo tropism … Read more DMPQ- What are directional and non-directional movements in plants?
