Cell Membrane
 Outer Shell of the Cell
 Separates the cell from the external
environment
 Regulates what comes into and out of
the cell
 Security system of the cell
Cytoplasm
 Jelly Like mixture
 Contains molecules and small cell
parts(organelles)
 Contains enzymes to drive chemical
reactions
DNA
 Long molecule containing information
 Controls cells activities
 Mutations can cause irregular cell
division
 Complex instructions
Nucleus
 Controls cells activities
 Stores DNA
 Large, Round/Oval Shape
 Is made up of the following parts:
 Nuclear Membrane
 DNA
 Nucleolus
 In both Plant and Animal Cells
Nuclear Membrane
Surrounds Nucleus
Selectively Permeable
Controls what moves into and out
of the nucleus
Both Plant and Animal Cells
Nucleolus
Found inside the nucleus
Creates Ribosomes
Both Plant and Animal Cells
Mitochondrion (Mitochondria)
Bean shaped with inner
membranes
Breaks down sugar molecules into
energy
Both Plant and Animal Cells
Ribosome
Small bodies that are free within
the cell or attached to E.R.
Produce Proteins
Created by the Nucleolus
Both Plant and Animal Cells
Endoplasmic Reticulum (ER)
Network of tubes or membranes
Carries materials through the cell
Smooth and Rough ER
Rough ER have Ribosome attached
Both plant and animal cells
Vacuole
Fluid-filled sacs
Store food, water, waste
Plants store large amounts of food,
have large vcacuoles
Both Plant and Animal Cells
Golgi Bodies
Packages proteins for transport
Tubes and membranes
Thought of as UPS or Post Office of
the cell
Lysosome
Small, round with a membrane
Breaks down larger food molecules
into smaller pieces
Digests old cell parts
Uncommon in Plants, common in
Animal Cells
Plant Cell Parts
Parts that are common only in
Plant cells include:
 Cell Wall
 Chloroplast
 Chlorophyll
Cell Wall
Outer Layer of Plant Cell
Rigid, strong
Made of cellulose
Provides Support, Protection
Allows H2O, O2, CO2 to pass into
and out of cell
Chloroplast
Green, oval
Uses energy from sun to make food
for the plant
Contain Chlorophyll
Chlorophyll
Very small, round, green
Provide pigment to the plant
Used during photosynthesis
