ORGANELLES

By: Paul Mendoza

Cell Membrane

Allows small molecules to pass freely

Keeps some things from entering the cell as well as leaving the cell

Cell Wall

Helps plants keep shape

Made of cellulose

Cytoplasm

Fluid that fells cell

Nucleus & Nucleolus

Nucleus: Brain of the cell; Controls the reproduction of a cell

Nucleolus: Produces ribosomes



Big image

Nuclear Membrane

Perforated by thousands of nuclear pore complexes that control the passage of molecules in and out of the nucleus

Centrioles

Helps cells divide (Mitosis and Meiosis)

Chromatin

The DNA of the nucleus with associated proteins

Ribosomes

Protein builder

Golgi Apparatus

Simple molecules combined to create complex ones

Absorbs proteins created in the rough ER, does it work on the protein, and it creates a secretory vesicle to release the protein into the cytoplasm

Endoplasmic Reticulum

Ribosomes carrying RNA from the nucleus attach to the rough ER, turn into fresh proteins, and go to the golgi

Mitochondria

Takes nutrients, breaks it down, creates energy rich molecules
Big image

Chloroplast

Use energy from sun to convert carbon dioxide and water into sugar
Big image

Lysosomes

Digest things such as food

Helps breaks down cells when they die

Peroxisomes

Absorbs nutrients that the cells need

Known for digesting fatty acids

Gets rid of toxins in the cell

Big image

Vacuole

Storing nutrients, breaking down waste, and helping the cell grow is the Vacuoles job
Big image

Cytoskeleton

A series of intercellular proteins that help a cell with its shape, support, and movement
