✅functions of the followi Question State the major functions of the following: (a) Plasma membrane      (b) Ribosome (c) Lysosome                    (d) Mitochondria (e) Golgi apparatus           (f) Cytoplasm (g) Asters of centrosome   (h) Chromosomes (i) Glycogen granule         (j) Vacuoles Solution Verified by Toppr The functions of the given are : (a) Plasma membrane  It separates the content of the cell from its surroundings. It regulates the entry of certain solids and ions into the cell. It maintains the shape of the cell that is the animal cell. (b) Ribosome Its main function is Protein synthesis. (c) Lysosome      Intracellular digestion and Destroy foreign substances. When a cell is old or injured this rapidly destroy organelles hence called suicide bags. (e) Golgi apparatus Synthesis and secretion of enzymes, hormones and etc. The formation of acrosome of sperm. (d) Mitochondria Release of energy form pyruvic acid produced in the cytoplasm in the form of ATP and helps in the Synthesis of respiratory enzymes. (f) Cytoplasm Different organelle is contained in it perform different functions. All metabolic activities occur in it. Medium of earlier steps of respiration (g) Asters of centrosome Present in an animal cell and helps during the process of mitosis.  (h) Chromosomes Chromosomes carry hereditary information or genes. (i) Glycogen granule Starch glycogen and fat containing granules serve as food for the cell. (j) Vacuoles Storage of water and other substances, food pigments and waste products. Give turgidity to the plant cell by pressing against a cell wall. @tutorial_education

POTENTIAL ENERGY •Potential energy is the energy possessed by a body because of it position or configuration. Potential energy can be •gravitational Potential energy or elastic Potential energy Gravitational Potential energy is given by the equation GPE=mg□h ~ the work done against gravity is equal to the change in gravitational Potential energy W=GpE the work done to move abody UPword is equal to increase in gravitational Potential energy and the work done to move the body word is equal to the decrease in gravitational Potential energy of the body Elastic Potential energy is the energy of the a body due to its configuration The extension (x) of as spring is given by the equation F=KX where (F) is the force and(K) is spring constant The energy stored in spring is given by the equation EpE=½kx² or EpE=½Fx The work done by the elastic force is equal to the change in elastic Potential energy W=◇EpE =½kx² - ½kx² REVIEW QUESTIONS 1. A.Question • solutions Given GpE=mgh GpE=mgh 9.81×150m g=9.81m/s =1471.5m joule h=150m B. Question ~ Given GpE =mgh = m 9.81 × 200 =1,962m joule C. QUESTIONS Given • solution W=□ EpE=½kx² - ½kx² = 1962- 140-mJ @tutorial_education @tutorial_education
