A. CELL THEORY
1) All living things are made
of one or more cells.
2) Cells are the basic
unit of structure and
function in living things.
3) Living cells come
only from other living
cells.
B) ANIMAL VS. PLANT CELLS:
No Cell wall
Small Vacuoles
No Chloroplasts

Large Vacuoles

Chloroplasts
C) SOME CELL TERMS &
STRUCTURES:
1) ORGANELLES:
• tiny organs in the cell.
2) CYTOPLASM:
• fluid filling inside the cell membrane.
• makes up the majority of cell’s mass.
Organelles
Cytoplasm
3) CELL MEMBRANE
• controls movement of materials into and
out of the cell
• holds cell together

membrane
Animal Cell
4) CELL WALL
• found in plant cells not animal cells
• provides strength and support for plant
cells.
• made of cellulose (long chains of sugar
molecules)

D) ORGANELLES OF CELLS:
1) Nucleus:
• the control center of the cell
• stores DNA
(a) nucleolus - dark spot inside the
nucleus, which makes ribosomes.
(b) nuclear membrane - controls
movement of materials in and
out of nucleus.
(c)
DNA - stores information for
making proteins

2) RIBOSOME
• tiny grain like
particles usually
found along the
E.R.
• proteins are

Proteins
Amino acids
3) Endoplasmic Reticulum (ER):
• makes lipids
• the delivery system of the cell for
compounds such as proteins through its
tubular connections.

4) Mitochondria:
• the “Power House” of the cell
• releases energy packets of ATP for use
in the cell.

5) Chloroplast:
• “Solar Panels” for capturing energy
• they use energy from sunlight to make
food in plant cells (i.e. glucose).

6) Vacuole:
Plant Cell
• “Storage Tanks” of the cell
• store water, food and waste.
Golgi complex
Animal Cell
7) Golgi body:
• packages and transports materials out
of the cell.
Vesicle with food
Animal Cell
Lysosome
8) Lysosome:
• “Clean-up and Recycling Crew”
• digest food particles, wastes, cell parts,
and foreign invaders.
