ALL LIVING ORGANISMS ARE MADE UP OF CELLS

•

CELL STRUCTRURE & FUNCTION

•

EUKARYOTESEXAMPLE: 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
