Biology - Cells and Microscopy

• Name the parts of an animal cell:

  Mitochondria, cytoplasm, nucleus, cell membrane.
• Name the parts of a plant cell:

  Mitochondria, cell wall, cytoplasm, vacuole, nucleus, cell membrane, chloroplasts.
• What does the nucleus do?

  Controls the functions and activities of a cell. Contains the instructions of making new cells or organisms.
• What is the function of a cytoplasm?

  Where most of the cell's reactions take place.
• Mitochondria


  Respiration occurs here - oxygen + sugar reacts to release energy the cells need.
• What is the function of ribosomes?


  The area where protein synthesis takes place. All proteins needed in cells are made here.
• What is the function of a chloroplast?


  Found in the green area of plants and help plants to undergo photosynthesis.
• What is the function of a vacuole?


  A space in the cytoplasm filled with sap which is important for keeping cells rigid to support the plant.
• What is the function of the cell membrane?

  Controls passage of substances in and out of the cell.
• What is the function of the cell wall?

  Protects the cell. Strengthens the cell wall and the structure of the cell.
• What is microscopy?

  Microscopy is the use of microscopes to visualize cells and their structures. There are 2 main microscopes, a light microscope and an electron microscope.
• A light microscope involves using rays of light to zoom in on the view of an image. A microscope uses lenses to focus on image. The disadvantages of light microscopes are low magnification and resolution, in comparison to an electron microscope.
• What is resolution?

  The ability to tell 2 or more objects apart.
• What is magnification?

  Magnification is how much the lenses can zoom into an image.
