Basic Cell Parts & Functions

Nota:

• Cells are so small that you need to use a microscope to see  them.   Every human, animal and plant is made up of trillions of cells.

1. The cell has many organelles. Five of these organalles are: Cell Membrane, Nucleus, Vacuole, Mitochondrion and Cytoplasm

   Nota:

   • The cell has many more organelles, all of which are just as important. A few other major organelles are: (1) nucleolus (2) ribosome (3) vesicle (4) rough endoplasmic reticulum (5) Golgi apparatus (6) cytoskeleton (7) smooth endoplasmic reticulum (8) cytosol (9) lysosome (10) centriole. 
   1. Cell Membrane - is a protective barrier for the cell. It  provides structure for the cell and controls what can enter or leave the cell.

      Nota:

      • Cell membrane - You can think of the cell membrane like the "skin" of the cell.
   2. Nucleus - controls the activities of the cell.

      Nota:

      • Nucleus - You can think of the nucleus like the "brain" of the cell. 
   3. Vacuole - holds water and food in the cell. It also holds waste that might hurt the cell.

      Nota:

      • Vacuole - You can think of the vacuole like a "storage compartment" of the cell. 
   4. Cytoplasm - a gel-like (jelly-like) substance that fills the cell and holds all the cell parts in place.

      Nota:

      • Cytoplasm - You can think of the cytoplasm like the "glue" of the cell. 
   5. Mitochondrion - takes in nutrients and turns it into energy   for the cell. It also helps the cell to breathe.

      Nota:

      • Mitochondrion - You can think of the mitochondrion like the "powerhouse" of the cell.
