CELLS
- Animal cells
- Nucleus - contains genetic
material that controls the
activities of the cell
- Cytoplasm - gel-like
substance where most of
the chemical reactions
happen. It contains
enzymes that control
these chemical reactions.
- Cell membrane - holds the
cell together and controls
what goes in and out of the
cell
- Mitochondria - these are
where most of the reactions
for respiration take place.
Respiration releases energy
that the cells need to work.
- Ribosomes - these are
where proteins are made
in the cell.
- Nucleus - contains genetic
material that controls the
activities of the cell
- Plant cells
- Plant cells normally contain
all the bits Animal cells do
plus a few extra.
- Cell wall - made of cellulose. It
supports the cell and strengthens it.
- Permanent vacuole - contains cells
sap, a week solution of sugar and salts.
- Chloroplast - these are where
photosynthesis occurs, which makes
food for the plant. They contain s
green substance called chlorophyll.
- Plant cells normally contain
all the bits Animal cells do
plus a few extra.
- Yeast cell
- Yeast is a microorganism.
- A yeast cell has a nucleus, cytoplasm and a
cell membrane surrounded by a cell wall.
- Yeast is a microorganism.
- Bacterial cells
- Bacteria are single-celled microorganisms
- A bacterial cell has a cytoplasm
and a cell membrane surrounded by
a cell wall.
- The genetic material floats in the
cytoplasm because bacterial cells
dont have a nucleus.
- Bacteria are single-celled microorganisms
