- Animal and Plant Cells
- Cell Structure
- NUCLEUS - controls all activities of the cell
- Contains chromosomes which carry genes that carry instructions for making new cells and organisms.
- CYTOPLASM - Chemical reactions take place here.
- a liquid gel in which the organelles are suspended
- CELL MEMBRANE - controls passage of substances in and out of cell
- MITOCHONDRIA - where aerobic respiration occurs
- Releases energy for the cell
- RIBOSOMES - where protein synthesis takes place.
- NUCLEUS - controls all activities of the cell
- Plant Cells only
- CHLOROPLASTS - Absorbs light so plant can make food by photosynthesis.
- contain green substance chlorophyll.

- NUCLEUS - controls all activities of the cell
- VACUOLE - keeps cells rigid for plant support
- filled with cell sap
- CELL WALL - made of cellulose that strengthens and supports plant.
- CHLOROPLASTS - Absorbs light so plant can make food by photosynthesis.
- Eukaryotic Cells
- Complex and include animal and plant cells
- Organisms made up of Eukaryotic cells
- They have 1.Cell membrane 2.Cytoplasm 3.Genetic information enclosed in a nucleus.
- Prokaryotic Cells
- Smaller and simpler eg bacteria. Single-celled organisms.
- Cytoplasm and cell membrane surrounded by cell wall (not made of cellulose)
- Genetic material found in single DNA loop
- May contain small rings of DNA called plasmids code for antibiotic resistance
- They have no nucleus, they have a single strand of DNA in the cytoplasm
