Parts of a Cell Seen with an Electron Microscope 1.6 – pg. 26-27
NAME:
1. What are organelles?
Organelles are specialized structures found in the cytoplasm of a cell.
2. Complete the table below.
Cell Structure Name
Mitochondrion
Ribosomes
Endoplasmic
Reticulum
Golgi Apparatus
Lysosomes
Nucleus
Cell Membrane
Cell Structure Function
Provides the cells with energy. Energy
generation is achieved through a process
called respiration that involves combining
sugar molecules with oxygen which produces
carbon dioxide and water. Powers every other
function of the cell.
Assembles proteins which are large molecules
needed for cell growth, repair and
reproduction.
A series of folded membranes responsible for
carrying materials through the cytoplasm.
Stores proteins. Different proteins, depending
on their functions, are placed into packages
called vesicles. Vesicles are carried to
perimeter of cell where they are released
outside the cell.
Garbage men of the cell. Use special proteins
to break down larger molecules into smaller
molecules. Smaller molecules are reused as
building blocks for larger molecules.
Lysosomes responsible for killing and
digesting invading organisms.
The control centre of the cell. It directs all cell
activities.
Controls movement of materials into and out
of the cell.

3. Predict what would happen to a cell if its mitochondria (plural of mitochondrion) stopped
working.
If a cell’s mitochondria stopped working, the cell would be unable to produce energy. All other
functions of the cell that require energy to take place would cease to occur and ultimately the cell
would die.
4. Cells lining the stomach release enzymes that aid digestion. Digestive enzymes are protein
molecules. Explain why many Golgi apparatuses are found in stomach cells.
Since I am told that digestive enzymes are proteins, and since I know that digestive proteins are
stored in Golgi apparati, therefore it would be logical to expect that a large number of Golgi apparati
would be found in the cells in the stomach.
