CBSE Class 8 - Biology - Cell Organelles, Location and Functions (#cbsenotes)

Cell Organelles, Location and Functions

Organelles	Present In	Description	Function
Cell Wall	Plants only	Outer most covering, stiff shape, made of cellulose	Protects the cell from temperature variation, inside water pressure and moisture, procvides structural strength
Cell Membrane	Both plants and animals	Plants inside the cell wall. Animal: thin outermost selectively permeable	Allows exchange of selected substance, supports the cell, separates the cell from its environment.
Nucleus	Both plants and animals	Oval shaped body	Control cell activities, transmits genetics characteristics
Cytoplasm	Both plants and animals	Thick jelly like fluid containing other cell organelles	Site of all life (metabolic) processes, protects cell organelles
Mitochondria	Both plants and animals	Rod shaped body	Site of respiration, releases energy form sugar, called power house of the cell
Golgi body	Both plants and animals	Parallel stacked vesicles	packaging and dispatch of proteins and lipids, helps in lysosomes formation
Endoplasmic reticulum	Both plants and animals	Networks of tubes and membrane	Transportation of materials.
Ribosomes	Both plants and animals	Small bodies, sometimes attached to endoplasmic reticulum	protein synthesis
Vacuole	Plant: single and large. Animal: very small or absent	Sac-like structure in cytoplasm	Stores food and water (cell sap)
Plastids	Only Plants	Small colored bodies in cytoplasm	Impart color to leaf, flower and fruit
Lysosomes	Generally animals	Membrane bound sac in cytoplasm filled with digestive enzymes	Eats up(digests) damaged cells and unwanted cell products
