Term
Eukaryote
Definition
an organism made up of cells that have a nucleus enclosed by a membrane, multiple chromosomes, and a mitotic cycle; eukaryotes include protists, animals, plants, and fungi but not archaea or bacteria
Term
Mitochondrion
Definition
in eukaryotic cells, the cell organelle that is surrounded by two membranes and that is the site of cellular respiration, which produces ATP
Term
DNA
Definition
deoxyribonucleic acid, the material that contains the information that determines inherited characteristics
Term
Cell Membrane
Definition
a phospholipid layer that covers a cell’s surface and acts as a barrier between the inside of a cell and the cell’s environment
Term
Gogli Complex
Definition
a cell organelle that helps make and package materials to be transported out of the cell
Term
Endoplasmic Reticulum
Definition
a system of membranes that is found in a cell's cytoplasm and that assists in the production, processing, and transport of proteins and in the production of lipids
Term
Organelle 
Definition
one of the small bodies that are found in the cytoplasm of a cell and that are specialized to perform a specific function
Term
Cell Wall
Definition
a rigid structure that surrounds the cell membrane and provides support to the cell
Term
Lysosome
Definition
a cell organelle that contains digestive enzymes
Term
Cytoplasm
Definition
the region of the cell within the membrane that includes the fluid, the cytoskeleton, and all of the organelles except the nucleus
Term
Cytoskeleton
Definition
the cytoplasmic network of protein filaments that plays an essential role in cell movement, shape, and division 
Term
Nucleus
Definition
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
Term
Ribosome
Definition

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

Term
Vesicle
Definition
a small cavity or sac that contains materials in a eukaryotic cell; forms when part of the cell membrane surrounds the materials to be taken into the cell or transported within the cell
Term
Vacuole
Definition
a fluid-filled vesicle found in the cytoplasm of plant cells or protozoans
Term
Nucleolus
Definition
the part of the eukaryotic nucleus where ribosomal RNA is synthesized
Term
Chloroplast
Definition
an organelle found in plant and algae cells where photosynthesis occurs
Term
Chorophyll
Definition
a green pigment that is present in most plant cells, that gives plants their characteristic green color, and that reacts with sunlight, carbon dioxide, and water to form carbohydrates
