Cell Parts and Functions GHSGT Review Day 7 Cell Parts and Functions

Prokaryotes Types of Cells Eukaryotes

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)

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?

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

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

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

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

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

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

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
