Cell Membrane
Controls the movement of substances through the cell
Cytoplasm
Where chemical reactions take place in the cell
Nucleus
Contains dan and controls the activities of the cell
Mitrochondria
Aerobic respiration
Ribosomes
For protein synthesis
Cell wall
Supports the cell and is made up of cellulose
Vacuole
keeps the cell turgid and is filled with cell sap
Chloroplasts
contains chlorophyll which absorbs sunlight for photosynthesis
Eukaryotic cells
large,DNA is enclosed and has sub cellular organelles {plant and animals}
Prokaryotic cells
small, DNA is loose and has rings of plasmid dna
magnification Equations
Actual size=image/magnification
Stem cells
Unspecialised cells that can differentiate into into may types of cells
Mitosis
- DNA replication
2.Nuclear membrane forms around each set of chromosomes
3.Parent cells divide into two daughter cels
