Control and Coordination
Science Solutions from Chapter -1 - Control and Coordination

Practice Other Topics from Control and Coordination
The nervous system of animals includes the brain and spinal cord. It helps control and coordinate all the body functions. The responses produced by the nervous system can be voluntary or involuntary.
This topic discusses coordination in plants. Plants respond to external stimuli in the form of movement and growth. The coordination between stimulus and a plant cell is achieved with the help of certain chemical messengers called hormones.
This topic states that in animals, various types of glands help secrete the chemical messengers known as hormones. Each hormone has a specific function and location within the body to perform its function. Adrenaline, insulin, testosterone, etc., are animal hormones.
