Parts of a cell

Nucleus

Nucleus

Control center of the cell

Nucleolus

Makes ribosomes

Nuclear pores

holes in the nuclear envelope that allow materials to pass in and out of the nucleus

DNA

A complex molecule containing the genetic information that makes up the chromosomes.

Nuclear membrane

controls what goes in and out of the nucleus

Ribosomes

Makes proteins

Golgi apparatus

A system of membranes that modifies and packages proteins for export by the cell

Mitochondria

Powerhouse of the cell

Smooth ER

Makes lipids

Rough ER

That portion of the endoplasmic reticulum studded with ribosomes.

Microtubules

Spiral strands of protein molecules that form a tubelike structure

Cytoplasm

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

Vacuoles

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

Chromosomes

threadlike structures made of DNA molecules that contain the genes

Cell membrane

A cell structure that controls which substances can enter or leave the cell.

Centrioles

Cell organelle that aids in cell division in animal cells only

Chromatin

Clusters of DNA and proteins in the nucleus of a cell

Lysosomes

Uses chemicals to break down food and worn out cell parts

Chlorophyll

A green pigment found in the chloroplasts of plants, algae, and some bacteria

Vesicle

A membrane bound sac that contains materials involved in transport of the cell.

Cell wall

A rigid layer of nonliving material that surrounds the cells of plant

Central vacuole

A large vacuole that rests at the center of most plant cells and is filled with a solution that contains a high concentration of solutes.
