Cells and cell structure

. All living things are made up of cells.

. The structure of these cells can differ and some cells may be specilised to a pirticullar function.

. To get in or out of these cells, dissolved substances have to cross the cell membrane.

a) Most human and animal cells have a:

. necleus (controls the activities)

. cytoplasm (controlls the chemical reactions, within the cell ONLY)

. cell membrane controls the passage of dissolved substances in or out of the cell.

. mitrochondria (releases energy through respiration)

. ribosomes (where protein synthesis occurs)

b) Plants and agal cells have:

. cell wall (holds the cell together giving the plant its turgid form. ONLY found in plant and agal cells, not HUMAN)

. chloroplast (asorbs light energy and turns into food. ONLY found in plant and agal cells)

c) Bacteria cells have:

. cytoplasm


. Cell wall
