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

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

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

Nucleus• Function:Control center of cell
Stores hereditary information

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

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

Mitochondria
• Powerhouse of the cell, rod-shaped
• Function: Converts chemical energy for cell metabolism
![Page 10: GHSGT Review Day 7 Cell Parts and Functions. Prokaryotes Eukaryotes.](https://reader037.fdocuments.us/reader037/viewer/2022110400/56649db25503460f94aa1b96/html5/thumbnails/10.jpg)
Plastids (plant cells only)
• Structures that contain chloroplast
• Function: conversion of light energy into chemical energy, store food

Golgi Bodies• Flattened
membrane sacs
• Function: Packaging and distribution of materials in the cell
![Page 12: GHSGT Review Day 7 Cell Parts and Functions. Prokaryotes Eukaryotes.](https://reader037.fdocuments.us/reader037/viewer/2022110400/56649db25503460f94aa1b96/html5/thumbnails/12.jpg)
Lysosomes• Storage vesicle
• Function: Digestion, waste removal

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

Vacuoles• A spherical
vesicle
• Function: Digestion, storage, and elimination
![Page 15: GHSGT Review Day 7 Cell Parts and Functions. Prokaryotes Eukaryotes.](https://reader037.fdocuments.us/reader037/viewer/2022110400/56649db25503460f94aa1b96/html5/thumbnails/15.jpg)
Microfilaments and Microtubules
• Fibers of tubes of protein
• Function: Structure and support as well as movement of internal cell parts
![Page 16: GHSGT Review Day 7 Cell Parts and Functions. Prokaryotes Eukaryotes.](https://reader037.fdocuments.us/reader037/viewer/2022110400/56649db25503460f94aa1b96/html5/thumbnails/16.jpg)
Cilia and Flagella• Short and long
extensions of the surface of the cell containing microtubules
• Locomotion and production of currents that draw in food.

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

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