- Cell Organelles
- Nucleus
- Only in eukaryotic cells and can be seen under a light microscope.
- Rough and Smooth Endoplasmic Reticulum
- They are flattened membrane sacs called cisternae. The smooth doesn't have ribosomes and they are one continuous memrane.
- Smooth ER creates the lipids that the cell needs.
- Rough ER transports proteins made on the ribosomes.
- Lysosomes
- Spherical sacs surrounded by a single membrane.
- Contains enzymes which break down materials eg white blood cells break down invading microorganisms
- Found only in animal cells but not red blood cells.
- Mitochondria
- Double membrane, the inner has folds called cristae. The central part of the mitochondrian is called the matrix.
- Produce ATP (energy) during respiration. The activities in the cell are powered by the ATP.
- Golgi apparatus
- Receives and modifies the proteins then packages them in vesicles so they can be transported.
- Eukaryotic cells only
- Chloroplasts
- Two membranes filled with fluid, inner membrane has thylakoids (a stack is a granum)
- The site of photosynthesis, carbohydrate molecules are made from CO2 and water.
- Only found in plant cells.
- Nucleus
- There are nuclear pores on the nuclear envelope and a dense spherical structure called the nucleoulus
- Nucleus
- Only in eukaryotic cells and can be seen under a light microscope.
- Nucleus
- It houses the cell's genetic materials, the chromatin has DNA and proteins.
- Cytoskeleton and centricles

- Rough and Smooth Endoplasmic Reticulum
- Cytoskeleton is a web of fibres inside the cytoplasm. There are three types of fibres.
- Cell Organelles
- The cytoskeleton supports the cell and the centrioles help in the completion of cytokinesis. In animal cells they help with cell division.
- Cytoskeleton and centricles
- Cytoskeleton is a web of fibres inside the cytoplasm. There are three types of fibres.
- Cytoskeleton and centricles
- Found only in eukaryotic cells and can't be seen under microscopes.
- Ribosomes
- They are very small and some are alone, others are bound to the ER. They have no membranes.
- The site of protein synthesis in the cell. mRNA is used here to assemble proteins from amino acids.
- In prokaryotic cells they are much smaller but found in all three types of cell.
- Found in eukaryotic cells only.
- Large stack of folded membranes. Contains vesicles and has cisternae.
