2- Science Starter:
Two vocabulary words-
Chromosomes- A self-replicating body present in the
cells of higher plants and animals, especially
observable during mitosis.
Cell Cycle- Starts with the formation, then the growth
and development, and finally death. Each cell has their
own cycle, and it goes at it’s own pace.

Cell Parts & their Function

5. It is the basic unit of living things.
What is a Cell?
A cell is the smallest unit that is capable of performing life functions.
It is the basic unit of living things.

6. Cell Theory All living things are made up of cells.
Cells are the smallest working units of all living things.
All cells come from preexisting cells through cell division.

7. Examples of Cells Amoeba Proteus Plant Stem Bacteria Red Blood Cell
Nerve Cell

8. Cell Organelles
Cell Parts are referred to as organelles.

9. Cell Wall Most commonly found in plant cells & bacteria
Supports & protects cells
Cell Wall

10. Cell Membrane protective layer around all cells
allows food and oxygen into the cell and waste products out of the cell.

11. Cytoplasm Gel-like material Surrounded by cell membrane Cell Wall

12. Nucleus contains instructions for everything cell does; includes DNA

13. Ribosome Each cell contains thousands
Make proteins which repairs cells
(Think of it like a battery plant!)
Found on ER & floating throughout the cell

14. Endoplasmic Reticulum (ER for Short)
Moves materials around in cell
(Like a highway)
Smooth type: lacks ribosomes
Rough type : ribosomes embedded in surface

19. Lysosome
A lysosome is basically a specialized vesicle that holds a variety of enzymes. Used to digest food or break down the cell when it dies.
