Coordination is the ability to use different parts of the plant together, smoothly and efficiently. Growth in plants is generally of two types it can either be growth dependent or growth independent. It is the movement of a plant in response to a stimulus. Answer: Coordination in human beings is carried out both by the nervous as well as the hormonal system. To begin with, control is the ability to start, slow down or stop anything whereas coordination is simply the working together of various parts/organs in an organism. There are 2 modes of control & coordination, chemical & nervous. Plants respond to these environment stimuli by coordinating their hormones which acts as chemical messengers. Control and Coordination in Plants Assignment Help. Phototropism. light, water, gravity Their responses are usually much slower than animals; They respond to stimuli by producing a growth hormone called auxin which controls the direction of growth of roots or stems; They grow either towards a stimulus (known as a positive response) or away from a stimulus (known as a negative response) Co-ordination: Working together of various organs of an organism in a systematic manner to produce a proper response.
