Cell Parts and Functions

2. Prokaryotes
Types of Cells
Eukaryotes

3. Prokaryotic Cell – has no organized membrane between DNA and cytoplasm and not true organelles bound by a membrane. Ex. - bacteria

4. Eukaryotic Cell – have a true nucleus with a nuclear membrane and organelles. (most cells of plants and animals)

5. An organelle is to a cell as a _______ is to a body?
Organelles of the Cell
An organelle is to a cell as a _______ is to a body?

6. Nucleus
Function:
Control center of cell
Stores hereditary information

7. Endoplasmic Reticulum
Folded membrane in the cytoplasm
Function: protein synthesis, distributes materials thru the cell, Smooth ER also helps remove toxins

8. Ribosomes Round-shaped structures in the cytoplasm
Function: Site of protein synthesis

9. Powerhouse of the cell, rod-shaped
Mitochondria
Powerhouse of the cell, rod-shaped
Function: Converts chemical energy for cell metabolism

10. Plastids (plant cells only)
Structures that contain chloroplast
Function: conversion of light energy into chemical energy, store food

11. Golgi Bodies Flattened membrane sacs
Function: Packaging and distribution of materials in the cell

12. Click here to see an interactive lysosome
Lysosomes
Storage vesicle
Function: Digestion, waste removal

13. Microbodies Membranes containing enzymes
Function: Conversion of fats to carbohydrates, discharge of waste

14. Vacuoles A spherical vesicle
Function: Digestion, storage, and elimination

15. Microfilaments and Microtubules
Fibers of tubes of protein
Function: Structure and support as well as movement of internal cell parts

16. Cilia and Flagella
Short and long extensions of the surface of the cell containing microtubules
Locomotion and production of currents that draw in food.

17. Centrioles Short packs of tubes near the Golgi bodies
Necessary for cell reproduction within some cells

18. Cell Wall Rigid membrane surrounding the contents of a plant cell
Supports and gives shape to plants
