Once upon a time...you were a tiny little egg cell
That met a handsome little sperm cell. . .
Things went well, and they hit it off!
That’s you!

That’s you!
The sperm cell fertilized the egg cell and formed a
zygote. . .

What had to happen in order to change the four cells you saw on the last slide to the small fetus you viewed on this slide?
![Page 22: Cell Presentation](https://reader034.fdocuments.us/reader034/viewer/2022042815/557d241bd8b42a7a608b46df/html5/thumbnails/22.jpg)
What had to happen in order to change the four cells you saw on the last slide to the small fetus you viewed on this slide?
The cells had to differentiate from stem cells, and they had to divide so the animal could grow

Just like different cells have different functions based on their structure,
different parts of the cell (organelles) have specificfunctions as well

The cytoplasm
*The cytoplasm is the liquid and organelles inside the cell.
*Nutrients are dissolved in it.
*Materials the cells needs are also dissolved in the liquid.

Function: It stores DNA (genetic information) in the form of chromosomes
![Page 44: Cell Presentation](https://reader034.fdocuments.us/reader034/viewer/2022042815/557d241bd8b42a7a608b46df/html5/thumbnails/44.jpg)

![Page 45: Cell Presentation](https://reader034.fdocuments.us/reader034/viewer/2022042815/557d241bd8b42a7a608b46df/html5/thumbnails/45.jpg)
Mitochondria
How does the structure of this organellerelate to its function?
![Page 46: Cell Presentation](https://reader034.fdocuments.us/reader034/viewer/2022042815/557d241bd8b42a7a608b46df/html5/thumbnails/46.jpg)
Mitochondria
How does the structure of this organellerelate to its function?
It converts sugar into ATP through cellular respiration - the folds of the inner membrane increase surface area.

![Page 49: Cell Presentation](https://reader034.fdocuments.us/reader034/viewer/2022042815/557d241bd8b42a7a608b46df/html5/thumbnails/49.jpg)
The ribosome
Function:Along with the nucleus and the
endoplasmic reticulum, the
ribosome helps create new
molecules for the cell
(proteins)
![Page 50: Cell Presentation](https://reader034.fdocuments.us/reader034/viewer/2022042815/557d241bd8b42a7a608b46df/html5/thumbnails/50.jpg)
Lysosomes
Lysosomes are organelles that containenzymes that help the cell break down waste,
food, and dead cell parts
![Page 51: Cell Presentation](https://reader034.fdocuments.us/reader034/viewer/2022042815/557d241bd8b42a7a608b46df/html5/thumbnails/51.jpg)
How is a plant cell different from an animal cell?
![Page 52: Cell Presentation](https://reader034.fdocuments.us/reader034/viewer/2022042815/557d241bd8b42a7a608b46df/html5/thumbnails/52.jpg)
Plant cells contain cell walls for structure
They have a cell wall in addition to a cell membrane. It is much more rigid, and it provides a framework for the
cell.
![Page 53: Cell Presentation](https://reader034.fdocuments.us/reader034/viewer/2022042815/557d241bd8b42a7a608b46df/html5/thumbnails/53.jpg)

Plant cells contain chloroplasts
Chloroplasts add in photosynthesis by absorbing sunlight
![Page 56: Cell Presentation](https://reader034.fdocuments.us/reader034/viewer/2022042815/557d241bd8b42a7a608b46df/html5/thumbnails/56.jpg)

Plant cells contain chloroplasts
Chloroplasts add in photosynthesis by absorbing sunlight
The large central vacuole
has several functions.
It can hold waste, and it helps
maintains a cell’s turgidity.
