Structure that contains the cell's genetic material in the form of DNA

Unicellular organism that lacks a nucleus

In eukaryotic cells, all cellular contents outside the nucleus; in prokaryotic cells, all of the cell's contents

Specialized structure that performs important cellular functions within a cell

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

Cell organelle that breaks down lipids, carbohydrates, and proteins into small molecules that can be used by the rest of the cell

Network of protein filaments in a eukaryotic cell that gives the cell its shape and internal organization and is involved in movement

Structure in an animal cell that helps to organize cell division

Cell organelle consisting of RNA and protein found throughout the cytoplasm in a cell; the site of protein synthesis

Internal membrane system found in eukaryotic cells; place where lipid components of the cell membrane are assembled

Organelle in cells that modifies, sorts, and packages proteins and other materials from the endoplasmic reticulum for storage in the cell or release outside the cell

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

Cell organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell to use

Strong, supporting layer around the cell membrane in some cells

Flexible double-layered sheet that makes up the cell membrane and forms a barrier between the cell and its surroundings

Property of biological membranes that allows some substances to pass across it while others cannot; also called semipermeable membrane
