The Cell: What are its parts?

1
The CellWhat are its parts?
2
NUCLEUS

• Controls all the chemical reactions that happen
  in the cell.
• Contains the cells DNA.

3
E.R.

• Carries the proteins from the ribosomes.

4
RIBOSOMES

• Where proteins are made.
• Necessary for the DNA to work.
• ALL cells have these.

5
GOLGI

• Packages the proteins.
• Often connected to the E.R.

6
MITOCHONDRIA

• Where sugar is turned into usable energy.

7
LYSOSOMES

• Bags of enzymes.
• Allows the cell to self destruct.

8
VACUOLE

• Holds things for the cell, often WATER.
• Can also hold food.

9
CYTOPLASM

• It is the water inside the cell.

10
CELL MEMBRANE

• Controls what goes in and out of the cell.

11
CELL WALL

• Gives the cell shape and strength.
• Plants have these, animals do not.
• Made of cellulose.

12
CHLOROPLAST

• Where photosynthesis happens.
• Plants have these and animals do not.
• These are green.

13
PART II

• What are the differences between animal cells
  and plant cells?

14
1

• Animal cells are ROUND,
• plant cells are RECTANGULAR.
• ANIMAL PLANT

15
2

• Plant cells have cell walls.
• Animal cells dont have cell walls.
• The cell wall is very obvious around this onion
  cell.

16
3

• Plant cells have CHLOROPLASTS.
• Animal cells dont.
• We cant do photosynthesis because
• we dont have chloroplasts.

17
4

• Plant cells usually have
• a large water vacuole.
• Animal cells dont.
• You can see the water vacuole takes up most of
  the plant cell.

18
Part III

• We know about plant and animal cells.
• What about OTHER kinds of cells?

19
PROTISTS

• A PROTIST is a very small organism.
• Its whole body is just one cell.
• This is an AMOEBA.

20
PROTISTS

• Compare the AMOEBA photograph with the drawing.

21
PROTISTS

• This is a PARAMECIUM.

22
PROTISTS

• This is a EUGLENA.

23
PROTISTS

• We might see some protists when we look at pond
  water under a microscope.
