Cell Parts and Function Notes
1) Cell Membrane
-Surrounds the cell and controls the movement of materials
into and out of the cell.
-Made up of phospholipid molecules
2) Cytoplasm
-The jelly- like material that fills the space between the cell
membrane and the nucleus. It contains all of the organelles
and many reactions occur here.
3) Nucleus
-“The brain of the cell” or the Control Center of the cell”.
-The largest and most visible organelle
-Contains the DNA (genetic material)
-The nucleus is surrounded by a membrane .
- The dark spot in the center of the nucleus is called the
nucleolus, which stores materials that will be used later to
make ribosomes in the cytoplasm.
4) Mitochondria
-Known as the “Powerhouse of the Cell”
-Bean Shaped organelles which are surrounded by
two membranes (matrix)
- Uses oxygen to make ATP (energy)
