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
