Cell Theory
1.
All living things are
made up of one or
more cells.
2.
New cells are created
from pre-existing
cells.
3.
Cells are the basic
unit of life.
Plasma Membrane



Also Called: Cell Membrane, Phospholipid Bilayer, Semipermeable Membrane
Surrounds the cell and controls what enters and leaves
the cell (it is selectively permeable or semi-permeable).
Maintains homeostasis (equilibrium)
All Cells
Cytoplasm
 Jelly-like
material inside the cell.
 Holds organelles in “place”
 Made
mainly of water.
All Cells
Nucleus



Membrane bound organelle (Nuclear Membrane)
Controls cell activities
Contains the DNA (genome)
Eukaryotes
Mitochondria




Membrane Bound Organelle (Surrounded by
two membranes).
Provides cells with ENERGY
Converts Glucose into ATP (Energy)
POWERHOUSE of the cell
Eukaryotes
Ribosome
 Makes
Proteins.
 Found floating freely in the cells
cytoplasm and on the Rough ER.
All Cells
Rough Endoplasmic Reticulum/
Rough ER

Transports and Synthesizes (makes)
Proteins.
 Covered with RIBOSOMES.
Eukaryotes
Golgi Apparatus/ Golgi Bodies


Sac-like organelle that looks like a stack of
pancakes.
Modifies & ships proteins for their final
destination.
Eukaryotes
Smooth Endoplasmic Reticulum/
Smooth ER

Transports and Synthesizes (makes)
Lipids
Eukaryotes
Chloroplast

Membrane bound organelle
 Transforms solar energy into chemical
energy : PHOTOSYNTHESIS
 Contains chlorophyll, makes the cell green
Eukaryotes
Vacuole

Stores materials like water, food,
enzymes & waste
 BIGGER IN PLANTS – Central Vacuole
stores excess water
Eukaryotes
Lysosome
Contain digestive enzymes.
 Break down lipids, proteins, and
carbohydrates
 Cell’s
“Garbage Disposal”
Animal Cells
Cell Wall


Strong, rigid layer surrounding, outside the cell
membrane.
Provide support and protection to the plant.
Some Eukaryotes/ All Prokaryotes
Cilia/Pilus

Allows prokaryotes/eukaryotes to attach
to surfaces and to each other
 Allows them to transfer DNA (sexual
reproduction).
Prokaryotes
Flagella

Whip-like tails found in one-celled
organisms to aid in movement
