Cells

• A cell is the smallest unit of life that can live on its own, they make up all living organisms and their tissues.
• Eukaryotic cells are much larger than prokaryotic cells
• Eukaryotic cells contain membrane-bound organelles, while prokaryotic cells do not.
• eukaryotic cells keep their DNA in the form of chromosomes within a nucleus, whilst prokaryotic calls have their DNA loose in the cell.
• Animal and plant cells are eukaryotic cells.
• Bacterial cells are prokaryotic cells.
• Cell membrane, ribosomes, nucleus, mitochondria and cytoplasm are all found in plant and animal cells.
• cell membrane is a protective barrier on the outside of the cell and controls what goes in and out.
• the cytoplasm is the jelly-like liquid in the cell where most chemical reactions take place.
• Nucleus contains DNA
• Mitochondria carry out respiration so provide energy for the cell.
• ribosomes is where protein synthesis takes place.
• cell wall, vacuole and chloroplasts are only found in plant cells.
• cell wall is made of cellulose.
• Cell wall provides the cell with strength and structure.
• Vacuole contains cell sap
• Vacuole supports the cell.
• Chloroplasts are the site of photosynthesis
• Chlorophyll is green pigment that absorbs sunlight .
• Plasmids are small rings of DNA that are separate to the main DNA.
