Control and Coordination Class 10 all Definition
All our Dear CBSE Champs, Here we Net Ex. have included Control and Coordination Class 10 all Definition. All the given definition are important for this year board exam.
- Plant hormones: It can be also called as phyto hormones as phyto itself means plant. They are responsible for growth and development of plants. There are various types of hormones such as auxin, gibberellin, cytokinin, ethylene and abscisic acid. Every hormone plays a very important role in normal growth, development and health of plants, they also responsible for prevention of diseases.
- Tropic movement:The movement of plants when they receive any stimuli such as light, gravity, touch, chemicals or water. Tropic response can be positive or negative on the basis of direction of stimuli. Therefore there are 5 types of tropic movement such as phototropism, hydrotropism, gravitropism, thigmotropism and chemotropism. The examples of every tropic movement we can see practically in plants.
- Phototropism: When plants moves in response to stimuli that is light then it is termed as phototropism, plant make a movement in response to sunlight and bend towards the direction of light are called as phototropism.
- Hydrotropism: It can be defined as the movement of plant or bending of the plant towards the direction of water is called as hydrotropism. Hydro means water and tropism means bending towards the stimulus.
- Gravitropism: Gravitropism can be termed as movement of plant towards the stimulus in this case stimulus is gravity therefore it is called as gravitropism. Gravi means gravity.
- Thigmotropism: Thigmotropism can be defined as when any plant moves in response to a touch or bend towards the touch are called as thigmotropism.
- Chemotropism:Bending towards the chemicals care called as chemotropism. When any plant bend towards the stimulus of any chemical are called as chemotropism.
- Nastic movement:The nastic word itself suggest that movement will be non- directional. It also requires external stimuli such as light and temperature. This movement can be epinasty or can be hyponasty. So depending on the type of stimuli there are again 5 types of responses such as photonasty, nyctinasty, thigmonasty, thermonasty and seismonasty.
- Nervous system :Nervous system is specifically functions in the body for control and coordination, to regulate all the body movements and all senses. The structural and functional unit of nervous system is considered as neurons. The nervous system usually consist of two parts such as central nervous system and peripheral nervous system.
- Peripheral Nervous System :It usually support the functioning of central nervous system, and help in control and coordination of the body. It is made up of autonomic nervous system and somatic nervous system. The autonomic nervous system has two parts such as sympathetic nervous system and parasympathetic nervous system. They play important role in sensation to stimuli.
- Central Nervous System:CNS is the major and vital system present in the body. It consist of brain and spinal cord. The brain is enclosed by two cerebral hemisphere. Brain made up of three parts such as forebrain, midbrain and hindbrain. The forebrain contains frontal lobe, parietal lobe, occipital lobe and temporal lobe.
- Endocrine System:Endocrine system is the complex network of glands such as duct less gland, which helpful in growth, development, reproduction and daily activities. The master gland present in endocrine system is pituitary gland and though this gland various hormones release such as estrogen, progesterone, testeron, LH, TSH, GH, prolacin, oxytocin, ADH etc. All the hormones presence is required to live a healthy life.
