Organelles Midterm Review

Flashcards of Organelles and Definitions for the biology midterms.

Cell Wall

Made of cellulose or chitin. This tough structure surrounds some type of cells to provide structure and protection.

Chloroplast

Captures solar energy and converts to chemical energy in the form of carbohydrates.

Centriole

Organizes microtubes that serve as the cells skeletal system.

Cell/Plasma Membrane

Controls what enters and exits a cell.

Nucleus

Contains the genetic information for the cell (DNA) and directs the cell’s activities.

Nucleolus

Makes ribosomes inside the nucleus.

Vacuole

The storage organelle

Flagellum

The threadlike structure that provides locomotion to the cell.

Smooth ER

Manufactures lipids/membranes

Rough ER

synthesizes proteins for the cell membrane. Contains ribosomes to help finish the proteins.

Golgi Body/Apparatus

Sorts, modifies, and packages proteins and lipids to be exported from the cell.

Cytoplasm

The aqueous portion of the cell contains water, ions, and organic molecules.

Mitochondria

Produces energy for the cell (In the form of ATP) through cellular respiration.

Ribosomes

The site of protein synthesis, links amino acids together in the order specified by messenger RNA.

Vesicle

Moves things around
