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.

C) ANIMAL VS. PLANT CELLS:

Large

No Cell wallSmall VacuolesNo Chloroplasts

1) ORGANELLES:• tiny organs in the cell.

2) CYTOPLASM:• fluid filling inside the cell membrane.• makes up the majority of cell’s mass.

D) SOME CELL TERMS & STRUCTURES:

Organelles

Cytoplasm

3) CELL MEMBRANE

• controls movement of materials into and out of the cell

• holds cell together

Cell membrane

Animal Cell

• found in plant cells not animal cells• provides strength and support for plant

cells.• made of cellulose (long chains of sugar

molecules)

4) CELL WALL

Cell wall

Cell membrane

Plant Cell

1) Nucleus:

• the control center of the cell

• stores DNA

(a) nucleolus - dark spot inside the nucleus, which makes ribosomes.

E) ORGANELLES OF CELLS:

(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 made here Ribosome 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:

• “Storage Tanks” of the cell

• store water, food and waste.

7) Golgi body:

• packages and transports materials out of the cell.

Golgi complex

8) Lysosome:

• “Clean-up and Recycling Crew”

• digest food particles, wastes, cell parts, and foreign invaders.
