1.How does chemical coordination occur in plant? 2.what is the difference between the manner in which movement takes place in a sensitive plant and movement in our legs? |
| Answer» CHEMICAL coordination occurs in plants with the HELP of fluids secreted in plants known as phytohormones or plant hormones. ... For example auxin is responsible for the growth of the plants and cytokinin helps in cell division in the fast growing part of the plant such as plant hormones.MOVEMENT in sensitive plants Movement in our LEGS 1. The movement that takes place in a sensitive plant such as Mimosa pudica occurs in response to touch (stimulus). 1. Movement in our legs is an example of voluntary actions. 2. For this movement, the information is transmitted from cell to cell by electrochemical signals as plants do not have any specialised tissue for conduction of impulses. 2. The SIGNAL or messages for these actions are passed to the brain and hence are consciously controlled. | |
