1. What is the Plasma Membrane?
    Each living cell is a small compartment with an outer boundary. Controls what goes into and out of the cell.
  2. What is the Cytosol?
    A fluid inside each cell. Consist of mainly water but can contain some substances like sugar and salt.
  3. What is the Cell Wall?
    A rigid layer of polysaccharides lying outside the plasma membrane of the cells of plants, fungi, and bacteria. In the algae and higher plants it consists mainly of cellulose.
  4. What is the Nucleus?
    The central and most important part of an object, movement, or group, forming the basis for its activity and growth
  5. What is the Ribosome?
    A minute particle consisting of RNA and associated proteins found in large numbers in the cytoplasm of living cells. They bind messenger RNA and transfer RNA to synthesize polypeptides and proteins.
  6. What is the Mitochondria?
    An organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner part being folded inwards to form layers (cristae).
  7. What is the Lysosome?
    An organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in a membrane.
  8. What is the Cytoskeleton?
    a microscopic network of protein filaments and tubules in the cytoplasm of many living cells, giving them shape and coherence.
  9. What is the Peroxisomes?
    a small organelle present in the cytoplasm of many cells, which contains the reducing enzyme catalase and usually some oxidases.
  10. What is the Golgi Complex?
    The Golgi complex, also known as the Golgi apparatus or simply the Golgi, is a cytoplasmic organelle. It is found in eukaryote cells, as in animals, plants, and fungi. The complex was discovered by Camillo Golgi in 1898.
