The Vital Roles that Cell Structures Play
![Page 2: Unit b - section 2.2 vital roles that cell structures play](https://reader036.vdocument.in/reader036/viewer/2022062418/555ebf2ed8b42a74708b4ac8/html5/thumbnails/2.jpg)
Within each cell there are specialized structures called organelles that perform specific functions.
Think of them as living factories; they create everything they need to survive.

Nucleus
![Page 6: Unit b - section 2.2 vital roles that cell structures play](https://reader036.vdocument.in/reader036/viewer/2022062418/555ebf2ed8b42a74708b4ac8/html5/thumbnails/6.jpg)
Nucleus
The brain of the cell, it runs the whole show
Directs all activities within the cell such as growing, moving and reproduction.

Cell Membrane
![Page 8: Unit b - section 2.2 vital roles that cell structures play](https://reader036.vdocument.in/reader036/viewer/2022062418/555ebf2ed8b42a74708b4ac8/html5/thumbnails/8.jpg)
Cell Membrane
A “controlled gateway” that allows materials in and out of the cell
Uses diffusion
Is selectively permiable

Cytoplasm
![Page 10: Unit b - section 2.2 vital roles that cell structures play](https://reader036.vdocument.in/reader036/viewer/2022062418/555ebf2ed8b42a74708b4ac8/html5/thumbnails/10.jpg)
Cytoplasm
Is considered the “kitchen” of the cell
Is the space where all the nutrients are kept that assist the cell in its life processes
Largest part of the cell
![Page 11: Unit b - section 2.2 vital roles that cell structures play](https://reader036.vdocument.in/reader036/viewer/2022062418/555ebf2ed8b42a74708b4ac8/html5/thumbnails/11.jpg)
Mitochondria
![Page 12: Unit b - section 2.2 vital roles that cell structures play](https://reader036.vdocument.in/reader036/viewer/2022062418/555ebf2ed8b42a74708b4ac8/html5/thumbnails/12.jpg)
Mitochondria
In the shape of a peanut
Is called the “powerhouses” of the cell because all the chemical reactions take place
Turns the energy the cell receives into a form it can use
![Page 13: Unit b - section 2.2 vital roles that cell structures play](https://reader036.vdocument.in/reader036/viewer/2022062418/555ebf2ed8b42a74708b4ac8/html5/thumbnails/13.jpg)
Vacuoles
![Page 14: Unit b - section 2.2 vital roles that cell structures play](https://reader036.vdocument.in/reader036/viewer/2022062418/555ebf2ed8b42a74708b4ac8/html5/thumbnails/14.jpg)
Vacuoles
“Storage rooms” within the cell
Nutrients, water, and other substances are stored here
Animal cells commonly have many vacuoles
![Page 15: Unit b - section 2.2 vital roles that cell structures play](https://reader036.vdocument.in/reader036/viewer/2022062418/555ebf2ed8b42a74708b4ac8/html5/thumbnails/15.jpg)
Plant Cell
![Page 16: Unit b - section 2.2 vital roles that cell structures play](https://reader036.vdocument.in/reader036/viewer/2022062418/555ebf2ed8b42a74708b4ac8/html5/thumbnails/16.jpg)
Plant Cells
Have all of the organelles listed in the ANIMAL CELL, but has a few extra ones;› Cell Wall› Chloroplasts› Vacuoles (different)
![Page 17: Unit b - section 2.2 vital roles that cell structures play](https://reader036.vdocument.in/reader036/viewer/2022062418/555ebf2ed8b42a74708b4ac8/html5/thumbnails/17.jpg)
Cell Wall
![Page 18: Unit b - section 2.2 vital roles that cell structures play](https://reader036.vdocument.in/reader036/viewer/2022062418/555ebf2ed8b42a74708b4ac8/html5/thumbnails/18.jpg)
Cell Wall
The “frame” of the plant cell
Only found in plant cells, are a means of structure and support for the cell
Look like a GREEN BRICK WALL
![Page 19: Unit b - section 2.2 vital roles that cell structures play](https://reader036.vdocument.in/reader036/viewer/2022062418/555ebf2ed8b42a74708b4ac8/html5/thumbnails/19.jpg)

![Page 20: Unit b - section 2.2 vital roles that cell structures play](https://reader036.vdocument.in/reader036/viewer/2022062418/555ebf2ed8b42a74708b4ac8/html5/thumbnails/20.jpg)
Chloroplasts
The “solar panels” of the plant cell
Are found in the green parts of the plants
Carry out photosynthesis; convert the suns energy into food for the cell
![Page 21: Unit b - section 2.2 vital roles that cell structures play](https://reader036.vdocument.in/reader036/viewer/2022062418/555ebf2ed8b42a74708b4ac8/html5/thumbnails/21.jpg)
