• The Nucleus contains the genetic material that controls the activities of the cell and the instructions to make new cells and proteins
• The cytoplasm is a liquid gel/ "jelly-like" substance where most chemical reactions happen
• The cell membrane is a partially permeable barrier that surrounds the cell content, and controls what enters and leaves the cell
• The mitochondria is where aerobic respiration takes place, the reaction that transfers energy for cells to use
• The ribosome is where protein synthesis (using genetic code from DNA) takes place, making all the proteins needed in the cell
• The chloroplast is filled with a green substance chlorophyll, which absorbs light needed for photosynthesis
• The vacuole (permanent) contains a water liquid with sugar and salts called cell sap, which supports the cell from the inside and keeps it rigid
• The cell wall strengthens the cell and provides support for the cell. It is made of cellulose.
• A cell is the very smallest unit of living matter
• The small structures inside the cell are called organelles
• The difference between animal and plant cells is that plants cells have chloroplasts, vacuoles and cell walls whilst animal cells do not
