CELLS


The smallest organized form of living protoplasm
 Protoplasm: Living matter within a cell
Can be one simple organism
Amoeba


Millions of cells can make up an organ and have a specific
job. This would create a complex organism

2 Main Types of
CELLS

Eukaryotic: Cells with a NUCLEUS
 Plant, Animal, Fungi, & Most Protists

Prokaryotic: Cells WITHOUT a Nucleus
 Bacteria & Archaea
CELL MEMBRANE
FOUND IN:
Plant Cells
Animal Cells
Separates
cell from its environment
Controls substances passing in and out
of cell (analogy: like a window screen)
FOUND IN:
Plant Cells
Animal Cells
NUCLEUS
“Command Central” of the cell
 Contains chromosomes (analogy:
like a brain)

CHROMOSOMES
FOUND IN:
Plant Cells
Animal Cells
Structures that contain DNA
 DNA is instructions for the cell’s
activities (analogy: like a recipe)

NUCLEAR ENVELOPE
FOUND IN:
Plant Cells
Animal Cells
Membrane that surrounds the nucleus
 Lets materials in and out (analogy:
like a skull)


CYTOPLASM
FOUND IN:
Plant Cells
Animal Cells

Jelly-like substance that fills the cell
(analogy: like “packing peanuts”)
MITOCHONDRIA
FOUND IN:
Plant Cells
Animal Cells

Breaks down food into energy to be
used by the cell
(analogy: powerhouse of the cell)

RIBOSOMES
FOUND IN:
Plant Cells
Animal Cells
Small structures that make proteins
that the cell needs
 Ribosomes use the info from DNA to
make the proteins (analogy: factory
workers)


ENDOPLASMIC RETICULUM
FOUND IN:  Tube-like structure that contains
ribosomes
Plant Cells
Animal Cells  ER transports proteins throughout the
cell (analogy: roadways or tunnels)
GOLGI BODIES
FOUND IN:
Plant Cells
Animal Cells
Packages proteins made by the
ribosomes to be sent out of the cell
(analogy: the mailroom workers in a
factory)

FOUND IN:
Plant Cells
Animal Cells
LYSOSOMES

Helps cell digest proteins and old cell
parts - they basically clean up the cell
(analogy: custodians)
VACUOLES
FOUND IN:
Plant Cells (ONE BIG VACUOLE)
Animal Cells (MANY SMALL ONES)

Storage areas in cell for water, food and
waste (analogy: water tank or refrigerator)
CELL WALL
FOUND IN:
Plant Cells
Rigid outer layer made of cellulose
 Supports and protects plant cells
(analogy: wall surrounding a castle)

PLASTIDS
FOUND IN:  Contain pigments that give plants their
Plant Cells
color (analogy: human skin tones)
CHLOROPLASTS
FOUND IN:  Plant cell structures that contain the
Plant Cells
pigment CHLOROPHYLL (green
pigment)
 Chlorophyll traps energy from the sun
for photosynthesis (analogy: solar panels
