The control and coordination in plants is done by plant hormones (or phytohormones) There are four major types of plant hormones (or phytohormones) which are involved in the control and coordination in plants. However, the plants do not have a nervous system. Many plant hormones are responsible for various kinds of movements in plants. Movement dependent on growth Control and Coordination in Plants Plants also show movement by growth of their various parts. Largest part of the brain is-----. View example Photographism. Facebook. Chemical coordination in plants Growth and development in plants is possible because of plants hormones or phytohormones Auxin, Gibberellin, cytokinin, abscisic acid, and ethylene are examples of phytohormones Chemical coordination in animals Carried out with the help of hormones Solution : Deficiency of iodine causes goitre. Plants use chemical means for control and coordination. (v) Abscissic acid - It is a growth inhibitor that results in dormancy and abscission. Auxin is also involved … Plants use chemical means for control and coordination.  Animals have nervous system and endocrine system for control and coordination. Control and Coordination in Animals and Plants; Control and Coordination in Animals and Plants. The roots of a plant certainly grow towards water no matter what the circumstance . It can be either be positive tropism or negative tropism. Plants respond to light, touch, gravitational force and other stimuli. Elaborate. Many plant hormones are responsible for various kinds of movements in plants. Plant do not have a nervous system. Growth in plants is generally of two types it can either be growth dependent or growth independent. In plants control and coordination is done by chemical . Furthermore, it retards leaf senescence. Question 2: A potted plant kept in a room tends to bend towards the direction of light. There are different types of hormones, which affect the growth of a plant. Overview. Performance & security by Cloudflare, Please complete the security check to access. It is the response of plants to water. However, when the plant moves away from the stimuli, it is termed as negative tropism. The petals of flowers like Moonflower, dandelion, etc open during the day and closes in the evening based on the light intensity. There are five main types of plant hormones. Plant Hormones: Auxins Auxions […] The quick reaction of Mimosa pudica to mechanical stimuli is an example. NCERT Solutions for Class 10 Science Chapter 2 Control And Coordination are provided here with simple step-by-step explanations. These solutions for Control And Coordination are extremely popular among Class 10 students for Science Control And Coordination Solutions come handy for quickly completing your homework and preparing for exams. StumbleUpon. There are five main types of plant hormones. As is seen the figure above, the stem and leaves of a plant will respond to sunlight by moving towards it. In this case, the growth of pollen tube is due to the chemical secretion by stigma. They are: (i) Phototropism – Bending towards light It is the movement of a plant in response to variations in light and temperature. Also read- Plant growth regulators But if plants coordinate too, why are we not … However, they do have comparable systems to bring similar functions. In conclusion, control and coordination in plants is equally important as in case of animals. Plants also respond to stimuli with the help of chemical compounds secreted by the cells. Plants lack nervous system and sense organs as animals have them e.g. Control & Coordination in Plants is the growth and development are in a coordinated manner. 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. Some plants are short, some are tall, some dense and some scanty. Elaborate. CONTROL AND CO-ORDINATION IN PLANTS Sunday, 19 July 2015. Central nervous system consists of -----and-----.
