  1. What is a Nucleus and it's function?
    Most cells only have 1 nucleus however in some cases they have many. The blob in the middle is Nucelous and contains RNA. The brains of the cell, nucleus directs cell activities while also containing a genetic material called chromosomes, which are made of DNA. The DNA tells the cell what proteins it needs to produce.
  2. What's an mitochondria and it's function?
    The Mitochondria’s function is to turn the food consumed into energy. Composed of many folded layers of membrane. Site of cellar respiration where the cells have energy (ATP). Not present in prokaryotes. Most abundant with high energy needs e.g muscle cells and cells of the kidney. Can see EM.
  3. What are ribosomes? What are their function?
    Protein builders of the cell. The site of protein synthesis. Proteins are used throughout the body. Different proteins have different functions. Ribosome reads the message from RNA as to which protein to make. Very small organelles, located in the cytosol. Can only be seem with a TEM. Sometimes attache to the endoplasmic Reticulum.
  4. What are lysosomes and their function?
    ysosomes are cellular organelles that contain acid hydrolase enzymes that break down waste materials and cellular debris. They can be described as the stomach of the cell. Lysosomes digest excess or worn-out organelles, food particles, and engulfed viruses or bacteria.
  5. What are vacuoles and their function?
    Vacuoles are storage bubbles found in cells. They are found in both animal and plant cells but are much larger in plant cells. Vacuoles might store food or any variety of nutrients a cell might need to survive. They can even store waste products so the rest of the cell is protected from contamination. Eventually, those waste products would be sent out of the cell.
  6. What are Chloroplasts and their function?
    Chloroplasts are organelles found in plant cells and eukaryotic algae that conduct photosynthesis. Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant.Composed of many layers of folded membrane. Found in L
  7. What's the rough ER?
    Rough ER is found throughout the cell but the density is higher near the nucleus and the Golgi apparatus. Ribosomes on the rough endoplasmic reticulum are called 'membrane bound' and are responsible for the assembly of many proteins. This process is called translation.
  8. What's the smooth ER?
    Smooth ER (SER) acts as a storage organelle. It is important in the creation and storage of lipids and steroids. Steroids are a type of ringed organic molecule used for many purposes in an organism. They are not always about building the muscle mass of a weight lifter. Cells in your body that release oils also have more SER than most cells.
  9. What's the golgi appartus?
    he Golgi apparatus gathers simple molecules and combines them to make molecules that are more complex. It then takes those big molecules, packages them in vesicles, and either stores them for later use or sends them out of the cell. It is also the organelle that builds lysosomes (cell digestion machines). Prepares and packages protein. Linked to the ER. Stacks of membranes in layers.
  10. What's the endoplasmic reticulum?
    Another organelle in the cell is the endoplasmic reticulum (ER). While the function of the nucleus is to act as the cell brain, the ER functions as a manufacturing and packaging system. It works closely with the Golgi apparatus, ribosomes.
