1. The Parts of the Cell
MS-LS1-2 Develop and use a model to describe the function of a cell as a whole and ways parts of cells contribute to the function. (SEP: 2; DCI: LS1.A; CCC: Structure/Function)

2. Introduction to Cells

3. Cells are the smallest structural and functional unit of an organism

4. Cell wall
The cell wall is the outermost border of the cell. It protects the cell and gives it shape.

5. Cell Membrane Cell Wall
in animals
Cell Membrane
in Plants
Cell Wall

6. Cytoplasm
*the fluid substance inside the cell that fills the space between organelles and allows for transport of substances*

7. Organelles Ribosomes (make Proteins) Golgi Body (Packages Proteins)
Rough Endoplasmic Reticulum (assembles proteins)
Smooth Endoplasmic Reticulum (makes hormones and lipids)
Vacuoles (Store nutrients)
Lysosomes (remove waste)
Mitochondria (powerhouse of the cell)
Centrosome (aides in cell division)
Chloroplast (plants – produces chlorophyll for Photosynthesis)

8. Organelles

9. *surrounds the outer boundaries of the nucleus*
Nuclear Envelope
Nucleolus
Nucleoplasm
*the central, dense middle of the nucleus – contains the genetic material*
*fluid that fills the space between the nuclear envelope and nucleolus*
*surrounds the outer boundaries of the nucleus*

10. Review Cells are smallest structural and functional unit in organisms
Made of cell wall/membrane, cytoplasm, organelles, and a nucleus
Plants have cell walls and chloroplasts, while animal cells have a cell membrane
