Prokaryotes

A single-celled organism that has no nucleus and has no membrane-bound organelles

Organelles

One of the small bodies that are found in the cytoplasm of a cell and that are specialized to perform a specific function

Nucleus

In a eukaryotic cell, a membrane-bound organelle that contains the cell’s DNA and that has a role in processes such as growth, metabolism, and reproduction

Eukaryotes

An organism made up of cells that have a nucleus enclosed by a membrane, multiple chromosomes, and a mitotic cycle

Cytoplasm

The region of the cell within the membrane that includes the fluid, the cytoskeleton, and all of the organelles except the nucleus

Chloroplast

Organelle found in plant and algae cells where photosynthesis occurs

Golgi Apparatus

A cell organelle that helps make and package materials to be transported out of the cell

Chromosome

In a Eukaryotic cell, one of the structures in the nucleus that are made up of DNA and protein; in a Prokaryotic cell, the main ring of DNA

Ribosome

A cell organelle composed of RNA and protein; the site of protein synthesis

Mitochondrion

In Eukaryotic cells, the organelle that is surrounded by two membranes and that is the site of cellular respiration, which produces ATP

Bacteria

Domain made up of prokaryotes that usually have a cell wall that usually reproduce by cell division

DNA

Material that contains information that determines inherited characteristics

Protein

Organic compounds that is made up of one or more chains of amino acids and that is a principal component of all cells

Photosynthesis

Process by which plants, algae, and some bacteria use sunlight, carbon dioxide, and water to produce carbohydrates and oxygen

Virus

Nonliving, infectious particle composed of a nucleic acid and a protein coat

Cell Wall

A rigid structure that surrounds the cell membrane and provides support to the cell
