Cells
Animal cells -Eukaryotic cells
Nucleus- controls activity of the cell
Mitochondria- Aerobic respirations occur
Cell membrane- Controls what goes in and out of cells, barrier between cell and
environment
Ribosomes- where proteins are made
Cytoplasm- where most chemical reactions occur
Plant cells- Eukaryotic cells

Nucleus- controls activity of the cell
Mitochondria- Aerobic respirations occur
Cell membrane- Controls what goes in and out of cells, barrier between cell and
environment
Cell wall- supports cell
Ribosomes- where proteins are made
Cytoplasm- where most chemical reactions occur
Chloroplast- Photosynthesis occurs
Vacuole- Contains cell sap which is a weak solution of sugar and salt
Bacteria cell- Prokaryotic cell

Plasmids- Rings of DNA
They have NO nucleus but instead a single strand of DNA (nucleoid)
