Cell membrane
Protective outer covering of all cells that regulates the interaction between the cell and environment.
Cell
Smallest unit of an organism that can carry on life functions.
Cell theory
States the all organisms are made of one or more cells, the cell is the basic unit of life,and all cells come from other cells.
Cell wall
Rigid structure that encloses, supports, and protects the cells of plants, algae, fungi, and most bacteria.
Chloroplast
Green, chlorophyll-containing, plant-cell organelle that uses light energy to produce sugar from carbon dioxid and water.
Cytoplasm
Constantly moving gel-like mixture inside the cell membrane the constantly heredity material and is the location of most of a cell's life processes.
Endoplasmic reticulum
Cytoplasmic organelle that moves materials around I
in a cell and is made up of a complex series of folded membranes;can be rough (with attached ribosome) or smooth (without attached ribosomes).
Golgi body
Organelles that package cellular materials and transport them within the cell or out of the cell.
Host cell
Living cell in which a virus can actively multiply or in which a virus can hide until activated by environmental stimuli.
Mitochondrion
Cell organelle that breaks down food and releases energy.
Nucleus
Organelles that controls all the activities of a cell and contains hereditary materials made of proteins and DNA.
Organ
Structure, such as the heart, made up of different types of tissues that all work together.
Organelle
Structure in the cytoplasm of a eukaryotic cell that can act as a storage site, process energy, move materials, or manufacture substances.
Ribosome
Small cytoplasmic structure on which cells make their own proteins.
Tissue
A group of similar cells that work together to do one job.
Virus
A stand of hereditary material surrounded by a protein coating.
