Organelles of the Cell

Ribosomes

Cellular instructions made of protein and rRNA that build proteins (nonmembranous).

Mitochondria

Convert the stored chemical energy in food molecules to stored chemical energy in molecules of adenosine triphosphate (ATP).

Rough Endoplasmic Reticulum

Has ribosomes attached to its surface and is associated with the nucleus and produces proteins for transport and use out of the cell.

Smooth Endoplasmic Reticulum

Provides lipid compounds and detoxifies material.

Golgi Complex

Recieves material from the ER and assembles/packages proteins and lipids for transport to different parts of the cell or for export outside of it.

Nucleus

Houses genetic information of the cell, directs cellular functions, makes rRNA.

Vesicles

Digest subcellular material, transport material out of the cell, enzymatic activities.

Lysosomes

Vesicles filled with digestive enzymes that engulf foreign particles and release digestive enzymes that hydrolyze the foreign particles.

Peroxisomes

Coverts hydrogen peroxide to water and oxygen.

Microvilli

Small extensions of the plasma membrane of some cells that increase the surface area of the cell.

Cillia

Sweeps materials across the surface area of the cell in one direction. Found in respiratory track, uterine tubes, ventricles of the brain, and ducts of the testes.

Flagella

A long, whip-like appendage that protrudes from a cell and acts primarily as an organelle of locomotion.

Pseudopods

Locomotion, capturing foreign particles.
