Cell Organelles
Prokaryotic Cells



A prokaryotic cell
lacks a nucleus and
membrane-bound
organelles.
Contains single
strand DNA in a ring.
Contains ribosomes.
Eukaryotic Cells

Eukaryotic cells are found in all
organisms except in the
Kingdoms Eubacteria and
Archaebacteria.

They contain a “true
nucleus” and
membrane bound
organelles.

An organelle is a tiny organ
found in cells.

Plasma (cell) membrane
Cell Wall
Cytoplasm
Nucleus
Nucleolus
Nuclear membrane
Ribosomes
Endoplasmic Reticulum
Golgi Apparatus
Centriole
Mitochondria
Lysosome
Vacuole
Chloroplasts
The Plasma Membrane is like the SKIN
of the cell.
•The Cell Membrane controls what
enters and leaves the cell.

The Nucleus is like the BRAIN of the cell.
• The nucleus is the control center
of the cell.
• It contains the genetic information
for the cell in the form of DNA
called chromatin.
• It is a membrane bound structure
usually found in the middle of the cell.
Nucleolus
• Inside Nucleus
• Produce ribosomes
The Mighty
The “Mighty” Mitochondria is the
POWERHOUSE of the cell.
•Mitochondria - Makes energy
in the form of ATP
• ATP are produced to “power”
the cell.
•The mitochondria are thought
to have once been a bacteria
that was taken into animal cells
and eventually became part of
the cell.
Vacuoles are the STORAGE
SPACES for cells.
• These are
membranous sacs
that can store food,
enzymes, wastes,
and other materials
needed by the cell.
• Plant cells have
large vacuoles for
water storage.

Cytoplasm
• Jello-like substance
where organelles are
embedded.
The Cell Wall is like a suit of ARMOR
around the cell.
•Cell Wall - Supports the cell.
•It is found in plant cells
NOT animal cells.
Chloroplasts are where PHOTOSYNTHES
occurs.
• Contain chlorophyll, a green pigment
that traps the energy from light.
• Found in plant cells and some protists,
NOT found in animal cells.
The Golgi Apparatus is the PACKAGING
CENTER of the cell.
• Golgi Apparatus - Packages and modifies proteins.
The Endoplasmic Reticulum is the cells
DELIVERY SYSTEM.
•Endoplasmic Reticulum (ER) Delivers proteins.
•A membranous tubular system
throughout the cell connecting
the nuclear membrane to the
cell membrane.
Lysosomes
• Specialized vacuole
that contains digestive
enzymes.
Ribosomes
• Protein synthesis
(makes proteins)
Centrioles
• Centrioles help in cell
division.
• They are found only in
animal cells.
Differences in Plant Cells &
Animal Cells
Plant Cells
• have a cell wall
• large vacuoles
for water
storage
• chloroplasts for
photosynthesis
Animal Cells
• Vacuoles
are smaller
• Centrioles
for cell
division
