Transcript Cell Organelles & Specialization

Cell Organelles
Pages 20-21
Organelles
Structures inside of cells that
perform different cell activities!
Also known as “little or tiny”
organs
Nucleus (Nuclei)
Known as the “control center” of the cell
Operates like our brain
Contains DNA instructions (our genetic
information).
Give the instructions for protein synthesis
NUCLEUS
Mitochondria (Mitochondrion)
Known as the “powerhouse” of the cell
This is the place where energy(ATP) is made
Contain folds called cristae
If you increase the surface area (# of folds),
MORE energy is made
Vacuole
Stores waste (mostly water)
Larger in plant cells than animal cells
Plants need to absorb excess water
Larger vacuole = more water
Smaller vacuole = less water
Chloroplast
ONLY Plant Cells have chloroplast
This is the place where photosynthesis takes
place – makes glucose!
Remember  photosynthesis is the reaction
plants use to make their own food
Ribosome
Site of PROTEIN PRODUCTION
RNA travels to ribosomes to make proteins
They look like small dots
Cilia & Flagella
• Help the cell move
• Cilia = short, hair-like structure
• Flagella = long, whip-like structure
Cytoplasm
• Gel-like substance throughout the
cell that holds the organelles in
place
Cell Wall
ONLY Plant Cells have a cell wall
Located on the outside of the plasma
membrane
Provides structure and support
Plasma Membrane
Can be called semi-permeable OR
selective
Allows certain material into
and out of the cell
Known as the “gate-keeper” of the
cell
Responsible for maintaining a
stable, internal environment
(HOMEOSTASIS)
Plasma Membrane
Also known as cell membrane
& phospholipid bilayer
Made of many phospholipids
Heads: Hydrophilic
(water loving)
Tails: Hydrophobic
(water fearing)
Plasma Membrane
• Proteins are found within the plasma membrane
– Channel Proteins  allow materials to pass
through
– Receptor Proteins  allows the cell to
communicate with other cells
Plasma Membrane
Cell-fies

How can I remember it?
Members only can come and go.
I'm a brick wall.
Sail through my plasma.
I'm the control center.
I am a "mighty" power house.
I'll store anything,(Hint: Vacuum Bags)
Make me something sweet to eat
I make “some” nice protein
