Q. How is the movement of leaves of the sensitive plant different from the movement of a shoot towards light?

Sol. Both movements are different. The movement of leaves of the sensitive plant for example-Mimosa pudica (touch me not) occurs in response to touch. This movement is independent of growth.

On the other hand, the movement of shoot towards light is directional and growth is dependent. This type of movement is known as phototropism.

Q. How do we detect the smell of an agarbatti (incense stick)? 

Sol. The forebrain is responsible for thinking. It has separate areas that are responsible for our hearing, smelling, sight, etc. The forebrain has regions that collect impulses from the various receptors. When the smell of an incense stick reaches us, our forebrain detects it. Then, the forebrain interprets it & we can detect smell of agarbatti.

Q. How does chemical coordination occur in plants?

Sol. In animals, control and coordination happens with the help of nervous system. Plants do not have a nervous system.

Plants respond to stimuli by showing movements. Various activities like growth, development, and responses to the environment in plants are controlled and coordinated by the hormones. These hormones are produced in one part of the plant body and are translocated to other needy parts. For example, a hormone produced in roots is translocated to other parts when required. The five major types of phytohormones are auxins, gibberellins, cytokinins, abscisic acid, and ethylene.
