Surrounds the cell
Gel-like material moves organelles around the cell
Nucleus

Stores DNA



Contains nucleolus
Ribosomes


Controls organism’s characteristics
Protein maker
Mitochondria

Uses O2 to break down food to release energy
Plant & Animal cell similarities
(con’t)

Vacuoles


Endoplasmic reticulum


Storage area for food, wastes, & water
System of foods to transport proteins
Golgi Bodies

Package and distribute proteins outside the cell
Plant & Animal cell differences

Plants cells have

Cell walls


Protects and gives plants struture
Chloroplasts

Used for photosynthesis
 Food making/energy
Only 1 nucleus
 Only one vacuole

Plant & Animal cell differences



Used for energy production
Many vacuoles
 Centrioles

Cells store & use energy

Plants get energy from sun


Use chloroplasts to trap sunlight and change
it into chemical energy
Energy store in chemical bonds btwn atoms
of H, C, O2 & form molecules



Atoms – smallest unit of matter
Matter – anything that takes up space
Molecule – smallest particle of a substance

2 atoms forms a molecule
• When chemical bonds are broken, energy is
released
•Cells can use the energy or store it
• Stored in ATP molecules
• When energy is needed, these molecules are
broken down to release it
•Mitochondria
• uses O2 to release the energy in the bonds
Cells that get their energy from
the sun are

Cells store & use information

Nucleus

Control center of a cell

Contains DNA



Storage of characteristic info
Stores info for cell’s activities
Activities

Protein maker



Cell need proteins to function
DNA & RNA work together to make protein
Reproduction


DNA determines the cell’s type
When needed, the cell divides & becomes 2 new cells – DNA
also divides so each new cell has DNA so they know what they
need to do
True/false: The nucleus controls
what eye color you have.
