Cells

• All living things are made of cells
• Cells are either prokaryotic or eukaryotic. Eukaryotic cells are complex and include all animal and plant cells. Prokaryotic cells are simpler and smaller.
• Eukaryotes are organisms that are made up of eukaryotic cells.
• A prokaryote is a prokaryotic cell.
• The different parts of a cell are called subcellular structure.
• The nucleus contains genetic material that controls the activiites of the cell.
• The cytoplasm is the gel-like substance where most of the chemical reactions happen.
• The cell membrane holds the cells together and controls what goes in and out of the cell.
• The mitochondria is where most of the reactions for aerobic respiration takes place. Respiration transfers energy that the cell needs to work.
• The ribosomes are where the proteins are made in the cell.
• Rigid cell walls are made of cellulose. It supports the plant cell and strengthens it.
• The permanent vacuole contains cell sap, a weak solution of sugar and salts.
• The chloroplasts are where photosynthesis occurs , which makes the food for the plant. They contain a green substance called chlorophyl, which absorbs the light needed for photosynthesis.
• Bacteria are prokaryotes.
• Bacteria have a cytoplasm, cell membrane, cell wall, singular circular strand of DNA, and one or more small circles of DNA called plasmids.
