1. CELL THEORY:
1. All living things are composed of
cells.
2. Cells are the basic units of
structure and function in living
things.
3. All cells are produced from other
cells.
3. What are organelles?
• Tiny structures inside a cell.
• They carry out specific jobs within the cell.
• Kind of like organs for a cell.
4. CELL MEMBRANE
• The cell membrane is the outer doors of
the cell.
FUNCTIONS:
• It lets things in and out of the cell
• It holds everything together.
5. CYTOPLASM
• A jelly-like fluid that contains all of the
organelles of the cell.
FUNCTIONS:
• Holds all the organelles inside of the cell in
a moving fluid.
13. MITOCHONDRIA
• Rod-shaped structures found in the
Cytoplasm.
FUNCTIONS:
• They convert food energy into energy the
other organelles use to do their job.
“POWERHOUSE OF THE CELL”
15. ENDOPLASMIC RETICULUM (ER)
• A maze of passageways in the Cytoplasm.
TWO KINDS OF ER IN ANIMAL CELLS:
1. Rough ER – Have Ribosomes attached
2. Smooth ER – No Ribosomes attached
FUNCTIONS:
• To carry proteins and other materials from one
part of the cell to other parts.
• Many of the cell’s chemical reactions occur
here.
18. LYSOSOMES
• Small round structures found in the
Cytoplasm. They contain digestive
enzymes.
• FUNCTIONS:
• They break down materials with their
digestive enzymes.
20. RIBOSOMES
• Small grain-like bodies found on the
Rough ER and floating around the
Cytoplasm. They are like protein
factories. There are more ribosomes in a
cell that any other organelle.
FUNCTIONS:
• They make Proteins
22. GOLGI COMPLEX
• Flattened sacs and tubes found in the
Cytoplasm.
FUNCTIONS:
• Receives proteins from other Smooth ER.
• Packages the proteins up.
• Sends them to other parts of the cell.
