Super-Dooper Cell
Notes
Parts of a Cell
1.
Cell (Plasma) Membrane--”gatekeeper”
 Encloses the cell (double layer of fat and
proteins)
 ALL cells have one
 Selectively permeable
Cell Membrane
See figure 3.2 page 58

2.
Cytoplasm: “Living stuff”
 Jello-like substance that gives the cell
shape and suspends the organelles (little
organs).
 All the chemical reactions take place here!
It’s a boppin’ busy place!

3.
Nucleus: “Control Center”



Usually near the middle (center) of the cell
surrounded by a nuclear membrane
Contains the genetic information “DNA”
Nucleolus: Place where ribosomes are made.

4.
Ribosomes: “protein factories”


Proteins are made here!!
Think spots or dots!

5.
Endoplasmic Reticulum (ER)-”Canal
System”




Transportation system
Compartmentalizes the cell
Rough ER-has ribosomes
Smooth ER-no ribosomes

6.
Golgi Apparatus
stack of flattened sacs
 Concentrates and Packages cell proteins
for shipping around the cell (like gift
wrapping)

7.
Mitochondria- “Powerhouse”

Respiration center--sugar is burned to
create Energy!

8.
Lysosome - “Garbage disposal, suicide
sac”



Contain digestive enzymes to break up
worn out cell parts and invaders like
bacteria
Sometimes digest really bad stuff and die
so the cell can live.
Look like waffles
Peroxisome


Membrane sacs containing enzymes to
detoxify harmful substances and disarm
free radicals.
Converts free radicals to hydrogen
peroxide then catalase converts that to
H2O and O2.

9.
Cytoskeleton- “Wonder bra”


Gives support and shape
Helps cells to move

10.
Centrioles - “cellular churros”


Helps cells to divide
Lie close to the nucleus

Vacuole- “Water Tower”


Stores water
Look like bubbles
Cell


Basic Unit of structure and function of all
living things
All organelles are inside the cell
