ALL LIVING ORGANISMS ARE MADE UP OF CELLS
CELL STRUCTRURE & FUNCTION
EUKARYOTES EXAMPLE: Plant Cell & Animal Cell
BASIC CELL TYPES 1. PROKARYOTES: Example Bacteria .
EUKARYOTIC CELL 1. CELL MEMBRANE 2. NUCLEUS 3. ORGANELLES
CELL MEMBRANE 1. Selectively permeable 2. Phospholipids 3. Proteins >> Integral >> Peripheral
CYTOPLASM 1. LIES BETWEEN THE CELL MEMBRANE AND NUCLEUS.
MITICHONDRION 1. TRANSFERS ENERGY FROM ORGANIC COMPOUNDS TO ATP 2. STRUCTURE:- Double layered Membrane Crystal Matrix
ENDOPLASMIC RETICULUM 1. Prepares proteins for export , Synthesizes steroids, Regulates Calcium levels , Breaks down toxic substances
GOLGI APPARATUS 1. Processes and Packages substances produced by the cell.
LYSOSOME Digests Molecules ,Old Organelles and foreign substances. Micro Filaments and Micro tubules contribute to the support movement and division of cells. Cilia and Flagella Propel cells through the environment, move materials over the cell surface tubules
NUCLEUS Stores Hereditary information in DNA, Synthesizes RNA and Ribosome
CELL WALL 1. Supports and protects the cell.
VACUOLE Stores enzymes and waste products.
PLASTID Stores food or pigments. One type (Chloroplast) transfers energy from light to organic compounds.
DIFFERENCES BETWEEN PLANT &ANIMAL CELLS No Cell wall No Chloroplast No Vacuole Cellulose Cell wall is present. Chloroplast Large Vacuole
