The basic unit of structure and function for all living organisms. Cells have three common components: genetic material, cytoplasm, and a cell membrane. Eukaryotic cells also contain specialized organelles
A subunit within a cell that has a specialized function
A form of life; an animal, plant, fungus, protist or bacterium
An anatomical unit composed of cells organized to perform a similar function
An anatomical system composed of a group of organs that work together to perform a specific function or task
A type of organism composed of one or more cells containing a membrane-bound organelles.
A single-celled organism that lacks a membrane-bound nucleus and specialized organelles
A membrane-bound organelle in eukaryotic cells functioning to maintain the integrity of the genetic material and, through the expression of that material, controlling and regulating cellular activities
endoplasmic reticulum (ER)
An organelle, consisting of folded membranes and sacs, responsible for the production, processing, and transportation of materials for use inside and outside a eukaryotic cell. There are two forms of this organelle: rough ER that has surface ribosomes and participates in the synthesis of proteins mostly destined for export by the cell and smooth ER that has no ribosomes and participates in the synthesis of lipids and steroids as well as the transport of synthesized macromolecules
An organelle found in plant cells and the cells of other eukaryotic photosynthetic organisms where photosynthesis occurs
An organelle found in eukaryotic cells responsible for the final stages of processing proteins for release by the cell
mitochondrion (plural: mitochondria)
A membrane-bound organelle found in most eukaryotic cells; site of cellular respiration, where ATP is made
A cellular structure composed of RNA and proteins that is the site of protein synthesis in eukaryotic and prokaryotic cells
A thin, phospholipid and protein molecule bilayer that encapsulates a cell and controls the movement of materials in and out of the cell through active or passive transport
The scientific study of life
Made up of a single cell
Made up of more than one cell
An anatomical unit composed of tissues serving a common function
A set of interacting or interdependent components, real or abstract, that form an integrated whole. An open system is able to interact with its environment. A closed system is isolated from its environment
Type of reproduction involving two different gametes (i.e., sperm and egg)
Type of reproduction that does not involve gametes; offspring are clones of parents
Cells in an organism can develop in different ways to perform different tasks. Cells in multicellular organisms are specialized to perform particular functions.
found in many organisms including plants, algae, fungi, and many prokaryotes. The cell wall provides support and protection for the cell.
small organelles containing enzymes used in the breakdown of lipids, carbohydrates, and proteins; acts as the "clean up" crew in the cell removing old organelles.
stores materials such as water, salts, proteins, and carbohydrates. In many plant cells, there is a single large vacuole filled with water.
network of protein filaments which help the cell maintain its shape; also involved in movement
material that is inside the cell membrane, but outside of the nucleus
Levels of Biological Organization
organelle --> cell --> tissue --> organ --> organ system --> organism (species)
An evolutionary theory which explains the origin of eukaryotic cells from prokaryotes. It states that several key organelles (ie mitochondria and chloroplasts) of eukaryotes originated as symbioses between separate single-celled organisms.
Process that allows the human body to maintain its core internal temperature. The state of having an even internal temperature is called homeostasis.
