Cell Organelles

Ribosomes

small round structures that make proteins

Cell Membrane

a thin layer around the cytoplasm of a cell

Mitochondria

Powerhouse of the cell, organelle that is the site of ATP (energy) production

Rough Endoplasmic Reticulum

System of internal membranes within the cytoplasm. Membranes are rough due to the presence of ribosomes. functions in transport of substances such as proteins within the cytoplasm

Golgi Complex

stack of membranes in the cell that modifies, sorts, and packages proteins from the endoplasmic reticulum

Endoplasmic Reticulum

contains collection of enzymes that perform special tasks that include the synthesis of membrane lipids and detoxification; the liver contains a lot

Nucleus

a part of the cell containing DNA and RNA and responsible for growth and reproduction

Centriole

structure in an animal cell that helps to organize cell division

Lysosome

cell organelle filled with enzymes needed to break down certain materials in the cell

Flagellum

a lash-like appendage used for locomotion (e.g., in sperm cells and some bacteria and protozoa)

Vacuole

cell organelle that stores materials such as water, salts, proteins, and carbohydrates

Cell Wall

A rigid layer of nonliving material that surrounds the cells of plants and some other organisms

Chloroplast

organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy

Nucleolus

The organelle where ribosomes are made, synthesized and partially assembled, located in the nucleus

Microtubules

fiber making up the cytoskeleton of a eukaryotic cell; forms the basis of structure and movement of cilia and flagella

Capsule

a sticky, gelatinous substance around the cell wall; allows cells to stick together or to the host cell

Cytoplasm

a jellylike fluid inside the cell in which the organelles are suspended

Eukaryote

A cell that contains a nucleus and membrane bound organelles

Nucleoid

An irregularly shaped section of a prokaryote that contains most (if not all) the genetic material

Prokaryote

A unicellular organism that lacks a nucleus and membrane bound organelles
