Term | Definition |
Cytology | the branch of biology concerned with the structure and function of plant and animal cells. |
Cell | the smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane. Microscopic organisms typically consist of a single cell, which is either eukaryotic or prokaryotic. |
Organelle | any of a number of organized or specialized structures within a living cell. |
Organism | Organism is an individual living thing, such as a plant, animal, bacterium, protest, or fungus. |
Unicellular | consisting of a single cell. |
Multicellular | having or consisting of many cells. |
Prokaryotic | a microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles. |
Prokaryotes | a microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles. Prokaryotes include the bacteria and cyanobacteria. |
Eukaroytic | An organism whose cells contain a nucleus surrounded by a membrane and whose DNA is bound together by proteins (histones) into chromosomes. |
Eukaryotes | an organism consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus. Eukaryotes include all living organisms other than the eubacteria and archaebacteria. |
Cell theory | a basic tenet of modern biology, that cells are the basic units of structure and function in living organisms. |
Virus | A minute organism that consists of a core of nucleic acid surrounded by protein. |
Tissues | any of the distinct types of material of which animals or plants are made, consisting of specialized cells and their products. |
Organs | a part of an organism that is typically self-contained and has a specific vital function, such as the heart or liver in humans. |
Diffusion/Passive transport | is a movement of ions and other atomic or molecular substances across cell membranes without need of energy input. |
Osmosis | a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane. |
Active transport | the movement of ions or molecules across a cell membrane into a region of higher concentration, assisted by enzymes and requiring energy. |
Semi-permeable | A membrane that is selectively permeable, being permeable to only certain molecules and not to all molecules. |
Phagocytosis | the ingestion of bacteria or other material by phagocytes and amoeboid protozoans. |
Pinocytosis | the ingestion of liquid into a cell by the budding of small vesicles from the cell membrane. |
