Organelle

A specialized subunit within a cell that has a specific function.

Vacuole

Stores water within a plant cell.

Endoplasmic Reticulum

The site of protein synthesis, transports materials within the cell.

Makes lipids, sometimes stores Ca++

The site of protein synthesis, transports materials within the cell

Cell Membrane

The aqueous region inside the cell (jelly-like).

 Gives the cell structure and holds organelles in place

 Surrounding the cell to regulate exchange of materials with surrounding environment

Nucleus

Organelle that manages all the cell functions in a eukaryotic cell.

Chloroplast

Contains chlorophyll, a green pigment that traps energy from sunlight and gives plants their green color.

Lysosomes

Digests excess or worn-out cell parts, food particles, invading viruses or bacteria.

Ribosome

Create proteins.

Mitochondria

Produces a usable form of energy for the cell.

Golgi Apparatus

Modifies, packages, and distributes proteins.

Cell Wall

Firm, protective structure that gives the cell its shape in plants and bacteria.

Nucleolus

Site where ribosomes are made.

Chromatin

Name for the collection of DNA in the nucleus of eukaryotic cells.

Cytoskeleton

Consists of hollow tubes which provide support for the cell.

Flagellum

Longer whip-like structures used for movement.

Prokaryotic

 lack membrane-bound organelles and a nucleus. They contain ribosomes, a cell wall, a plasma membrane, and cytoplasm

Eukaryotic

membrane-bound organelles, including a nucleus. Major organelles include the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, vacuoles, and chloroplasts (in plant cells)

Mitochondria

Powerhouse of the cell, generates ATP through cellular respiration.

Vacuoles

Store water, nutrients, and waste products
