Animal & Plant Cells (AQA GCSE Combined Science: Trilogy): Revision Note

Animal Cells
Eukaryotic cells have subcellular structures, each carrying out a particular function
Organelles are subcellular ‘compartments’ where specific processes take place within the cell
The main subcellular structures in animal cells are:
The nucleus
Cell membranes
Mitochondria
Ribosomes
Cytoplasm

Some cellular structures can only be seen when viewed with an electron microscope

Plant Cells
In addition to the subcellular parts found in animal cells, plant cells have:
A cell wall made of cellulose (algal cells also have this structural feature)
A permanent vacuole filled with cell sap
Plant cells found in the leaf and stem may also contain chloroplasts

The plant cell shown above contains chloroplasts, so it would be found in the leaves of a plant
