OrganellesOrganelles are cell parts that do specific jobs.
ProkaryotesProkaryotes have no nucleus.What organelles do plant cells have
that animal cells do not?

Cell Types
All cells have a phospholipid
cell membranecell membrane.All cells have DNADNA. Eukaryotic cells
have DNA in a nucleusnucleus.CytoplasmCytoplasm is a jelly like material that
makes up the inside of the cell.
Basic Cell Parts
DNA
Nucleus
Cell Membrane
Cytoplasm
What are cell parts called?There are 3 important cell systems.
Endomembrane SystemCell BoundariesEnergy Production
The Production Factory Cell Skins The Power Factories
Organelles
Organelles
1. 1. Production Factory.What do you think cells produce?
The Production Factory
From DNA to Protein
Nucleus Ribosome ProteinLet’s break it down.
From DNA to Protein
The NucleusNucleus is where the DNA is stored.
Messenger RNAMessenger RNA is made from the DNA.It leaves the nucleus from a porepore.
From DNA to Protein
RibosomesRibosomes make protein from mRNA.
Organelles
2. 2. Power Factories.Why do cells need energy?
Cell Energy Production
Cells Need Energy to do Work.
What kind of energy do cells use?
Hint: Think molecules.
ATP
Cell Energy Production
The mitochondriamitochondria is an organelle that makes ATP from glucose.
Like a
little
battery!

Cell Energy Production
All glucose comes from a process called…All glucose comes from a process called…
photosynthesisphotosynthesis
Cell Energy Production
The chloroplast chloroplast is the organelle that performs photosynthesis to make glucose.
Some glucose
is stored as starch and
some is used
by the
mitochondria to
make ATP.
Material Storage
VacuolesVacuoles are storage organellesPlant cells have a giant central vacuole central vacuole
for storage and cell support.
Organelles
3. 3. Cell Skin.For eating, protection, and support.
Cell Boundaries
The skin of a cell and the sacs that make up organelles are made of which lipid?
PhospholipidsPhospholipids.The Cell MembraneCell Membrane is the outer skin of all
cells.It is a semi - permeable barriersemi - permeable barrier that lets
certain things in and out of the cell.
Cell Boundaries
hydrophilic
hydrophilic
hydrophobic
Cell Membranes are lipid bilayerslipid bilayers.How are phospholipids different than
other lipids?
Cell Boundaries
The cell membrane has many membrane proteinsmembrane proteins stuck in it.Receptors – flags or tagsGates – allow things in or outEnzymes – do reactions
Cell Boundaries
A cell wallcell wall provides support and protection to a cell, it is placed over the cell membrane.Plant Cells
