NAME
STRUCTURE
FUNCTION
SKETCH
Cell Membrane
-double layered sheet of lipid molecules
-covers the outside of a cell.
-differentially permeable
- both dimensional liquid
-separates cell from outside environment
-gives bodily protection and allows import + export of chemicals
-maintains cell potential

Nucleus
-kept in focus on of cytoplasm
-contains DNA
-largest cellular organelle in animals
-enable cell to make special(prenominal) proteins
-RNA is produced in the nucleus
-control gene regulation

Cytoplasm
-75% water
-jelly like in texture
-organelles remain suspended
-site of umteen chemical reactions
-contains ribosomes
-cell expansion and growth takes place present.

Mitochondria
-enclosing outer membrane
-semi tranquil matrix
-contains enzymes
-contains proteins
-enable organelle to carry out aerobic reparation
-needed for many nada requiring processes
-produces ATP

Ribosome
-many ribosomes in any one cell
-located along rough endoplasmic reticulum
-composed of two parts large+small subnits
-aid manufacture of proteins
-MMA meets RNA here so amino acids bond
-site of protein synthesis

Endoplasmic reticulum (E.R)
-found as rough/smooth
-has a series of folded internal membranes
-network of tubes/vesicles and sacs
-smooth E.



R aids synthesis
-rough E.R makes protein
-specialized functions

Golgi body
-series of flattened sacs
-separated from cytoplasm by membrane
-contains enzymes which modify cargo proteins
-aids production and secretion of many proteins
-enabling the closing off of chemicals from each other
-synthesize a large number of different macromolecules

Lysomes
-specialised vesicles
-contains hydrolic enzymes
-contains digestive enzymes
Manufactures proteins and lipids
-contains powerful enzymes able to destroy cells if not contained in cytoplasm

Centriols
-two ill-judged cylinders
-contains microtubles
-barrel shaped
-aids cell division
-moves to opposite poles and...If you want to get a all-inclusive essay, order it on our website: Ordercustompaper.com
