Cells
- All cells contain:
- DNA
- In a double helix shape
- Contain the genetic code
- Organelles
- Helps the cell perform
a specific function
- Animal cells
- cytoplasm
- Where chemical
reactions take place
- Anaerobic respiration
- production of
enzymes an proteins
- Mitochondria
- Where aerobic respiration
takes place
- nucleus
- Where the DNA and code for making
enzymes and proteins within the cell
are held
- cell membrane
- Allows water and certain gassesin and
out but keeps other chemicals from
passing through
- Plant cells
- Cell wall
- strengthens cell
- Permanent vacuole
- Helps support the cell
- chloroplasts
- Contains the green pigment chlorophyll
which helps absorb light energy
- Contains some enzymes needed for
photosynthesis
- Microbial cells
- Bacteria cells
- Cytoplasm
- contains enzymes for both
aerobic and anaerobic respiration
- Cell wall
- Supports cell: unlike plants cells it
is not made of cellulose but
instead of proteins
- Cell membrane
- Allows certain gasses and
chemicals to enter and leave the
cell freely and acts as a barrier to
other chemicals and gasses
- DNA
- circular in shape and floats
freely in the cytoplasm
