1. 1. Prokaryotic 2 Types of Cells: Do not have a nucleus.
No membrane covered organelles.
Circular DNA

2. Eukaryotic Cells: Complicated Internal structure Membrane Contain a
covered
organelles
Contain a
nucleus
Linear DNA

3. Organelles – “Little Organs”
Cell structures
that carry out specific jobs
in cells.

4. Parts of a Cell-Organelles
Lysosomes
Golgi Apparatus
Chloroplasts
Chloropyhll
Cell Wall
Cell Membrane
Cytoplasm
Endoplasmic
Reticulum
Ribosomes
Mitochondria
Vacuoles
Cytoskeleton

5. The structure and function of cells
1. Cell wall-
Plants only!
Support and protection,
Strong and stiff.
Made of cellulose.
2.Cell membrane-
Both
Plants—just inside cell wall
Animals—outer covering
of cell
Made of phospholipids
DOOR

6. 4 jobs of the cell membrane:
Support and protection for the cell
Openings called pores in the membrane
Allow waste material to pass out of the cell.
Controls movement of things
in and out of cell
Forms a barrier between the
inside and outside of the cell.

7. 3. Cytoplasm-- CUSHION 4.Cytoskeleton-- SUPPORT
Clear, thick, jellylike substance
b/tween nucleus and cell membrane.
Constantly moves. Organelles float here.
Both
CUSHION
4.Cytoskeleton--
Web of proteins in cytoplasm.
Acts as skeleton. Keeps cell
membrane from collapsing.
Both
SUPPORT

8. Deoxyribonucleic Acid
Control center or
“brain” of the
cell that regulates
or controls all
activities of the cell.
BRAIN
5. Nucleus:
BOTH
Nucleolus—
Makes ribosomes
Chromosomes--
Humans-46
Inside Nuclear Membrane
Genes
DNA
Genetic material
Deoxyribonucleic Acid

9. 6. Endoplasmic Reticulum-
INTERSTATE SYSTEM
BOTH
Smooth ER & Rough ER (ribosomes attached)
Clear, tubular passageways in the cell through which substances are transported. Proteins and fats made here and carried around the cell.

10. 7. Ribosomes- PROTEIN MAKER BOTH Site of protein synthesis
Found through out the cell—also attached to the surface of the endoplasmic reticulum

11. 8.Mitochondria POWERHOUSE BOTH Cell’s energy factory!
Place where sugar is
broken down to release
energy
This process is called
Cellular respiration.
Energy is called—
ATP
(Adenosine Triphosphate)

12. 9. Lysosomes- CLEAN-UP CREW Digestion takes place here!
Mostly animals!
Digestion takes place here!
Contains enzymes that
break down food.
Digested food-sent to
mitochondria to provide energy to the cell.
Also digests old cell parts—
lysosomes “eat” them.
2 examples:
Frog’s tail, our fingers

13. 10. Golgi Apparatus- UPS of cell
BOTH
Packages and transports materials into andout of the cell.
Packing bubble --
Vesicle

14. full of water, they swell
11. Vacuoles-
STORAGE CENTER
BOTH
Food, water, and waste
are stored here
In plants, when the
vacuoles are
full of water, they swell
and make
the plant stand firm.
Gives flowers their colors!

15. 12. Chloroplasts FOOD PRODUCER Plant cells only!!
Photosynthesis takes places here!!
Chlorophyll—captures
sun’s energy converts
it into food for the cell!
Glucose--
simple sugar made
during this process

16. Large vacuole
Cell Wall
Chloroplasts

17. Endoplasmic reticulum
Ribosomes
Nucleus
Mitochondria + + + +

18. Classwork!
Complete a DLCD (Draw, Label , Color, and Define) of an animal and plant cell from pages in your science book.
First draw or sketch out plant and animal cell with pencil first.
Next, label ALL parts of both cells and give a BRIEF description of each on the back, bottom, or sides of your DLC.
Last, please color both cells.
Not homework. Put in folders at end of class.
