1. Cells Parts and Functions
Ag. Biology
Ms. Weigel

2. Two types of cells
Prokaryotic
Eukaryotic

3. Prokaryotic cells

4. Prokaryotic Cells Single Celled Lacks a nucleus
Smallest and most simplest cells
Ex: Bacteria

5. Parts
Cell Wall: Outer surrounding of the cell- protects from environment
Cell Membrane- double- layer of phosoplipids & proteins - essentially the “bag” that holds it together

6. Ribosome: where proteins are made
Flagellum- used for locomotion

7. Pili- hairlike appendage found on the surface of many bacteria.
Cytoplasm- Gel-like fluid

8. Eukaryotic Cells
Two Types
Animal Cells
Plant Cells

10. Cell Parts and Functions
Cell Membrane Protects the cell Lets things in and out of the cell Location: around the cell Nucleus Control center Location: inside the cell, near the center

11. Cell Parts and Functions
Nucleolus (Nucleoli) Makes ribosomes Location: inside the nucleus (dark spot) Nuclear Membrane Protects nucleus Lets things in/out of nucleus (pores) Location: around nucleus
cell

13. Cell Parts and Functions
Mitochondria Makes energy/powerhouse Location: in cytoplasm Golgi Bodies/Apparatus Packages and secretes (gets rid of) waste

14. Mitochondria

15. GOLGI APPARATUS

16. Cell Parts and Functions
Endoplasmic Reticulum (E.R.)
Transports materials and sends messages to all parts of the cell
Two types: smooth and rough (has ribosomes)
Location: attaches from cell membrane to nuclear membrane
Rough E.R.

19. Cell Parts and Functions
Ribosome Makes proteins Location: in cytoplasm or Attached to E.R. Vacuole Stores food and water Location: in cytoplasm

20. Vacuole

21. Cell Parts and Functions
Lysosome Contains digestive enzymes Destroys bacteria, old cell parts… Location: in cytoplasm Centrioles Helps the cell to divide

23. Cell Parts and Functions
Cytoplasm Gel-like substances, holds all Organelles in cell Location: in cell Chromatin/Chromosomes Contains genetic information/traits Location: in nucleus

24. Cell Parts and Functions
Cilia Short hair-like projections Used for movement Location: outside of cell Flagella Long whip-like tail

26. FLAGELLA

27. Cell Structures and Functions
Chloroplast
Traps suns energy and
Makes food
Location: in plant cells

28. Cell Wall Cell Wall Protects and supports plant Cells
Prevents water loss
Cellulose
Location: outer layer of plant cells

29. CYTOSKELETON
Function: Support structure of cell and transport materials/organelles throughout the cell.
The highway of the cell.
Made of Microtubules (thin hollow cylinders) and Microfilaments (thin solid cylinders)
Location: Inside the cell

30. CYTOSKELETON

31. Cell Structures and Functions
Plastids Stores extra food in Plant cells Location: in plant cell
