The jellylike material that makes up much of a cell inside the cell membrane, and, in eukaryotic cells, surrounds the nucleus. The organelles of eukaryotic cells, such as mitochondria, the endoplasmic reticulum, and (in green plants) chloroplasts, are contained in the cytoplasm. The cytoplasm and the nucleus make up the cell's protoplasm .
A cavity within the cytoplasm of a cell, surrounded by a single membrane and containing fluid, food, or metabolic waste. Vacuoles are found in the cells of plants, protists, and some primitive animals. In mature plant cells, there is usually one large vacuole which occupies a large part of the cell's volume and is filled with a liquid called cell sap. The cell sap stores food reserves, pigments, defensive toxins, and waste products to be expelled or broken down. In the cells of protists, however, there may be many small specialized vacuoles, such as digestive vacuoles for the absorption of captured food and contractile vacuoles for the expulsion of excess water or wastes.
An animal in the earliest stages of its development in the uterus or the egg, specif., in humans, from conception to about the eighth week
Any microscopic organism, esp. one of the bacteria, that can cause disease
Any of the oval or disc-shaped cells that circulate in the blood of vertebrate animals, contain hemoglobin, and give blood its red color. The hemoglobin in red blood cells binds to oxygen for transport and delivery to body tissues, and it transports carbon dioxide, excreted as a metabolic waste product, out of the tissues. The red blood cells of mammals have no nucleus, while those of other vertebrates do contain nuclei. Red blood cells are formed in the bone marrow.
A mature, red-colored blood cell containing hemoglobin and normally lacking a nucleus; red blood cell: it is a very small, circular disk with both faces concave
Any of various cells that in adult mammals are produced in bone marrow, have a nucleus but no hemoglobin, and function in the immune system by protecting against pathogens and aiding in tissue repair. White blood cells include neutrophils, eosinophils, basophils, lymphocytes, and monocytes, and they are found in blood, lymph, and certain tissues.
(Hematology, cytology, immunology) A white blood cell.

A cramped or uncomfortably confined space.
A room in a house, especially a bedroom.
A secluded room for study or relaxation.
The act or process of moving back or away, especially from something hazardous, formidable, or unpleasant:
A recess or partly enclosed extension connected to or forming part of a room.
Any small, specialized business market
(Anat.) Any of various recesses, glandular cavities, or follicles in the body
A small room or covered structure, especially one of rough construction, used for storage or penning animals.
The definition of a nook is a part of a room which is separate from the rest of the room, or a secluded spot.
Any similar passage or hole for shelter, refuge, etc.
A small, partially enclosed compartment with a table and seats, as in some restaurants
A being locked up, as in jail
(Chemistry) A functional entity consisting of certain atoms whose presence provides a certain property to a molecule, such as the methyl group.
(Now Brit.) A large building with many units in it, or a group of buildings regarded as a unit
A tightly knit group of zealots who are active in advancing the interests of a revolutionary party.
A receptacle, such as a carton, can, or jar, in which material is held or carried.
A group of people inside a political party, club, government, etc. working in a common cause against other such groups or against the main body
The definition of organization refers to the act of putting things into a logical order or the act of taking an efficient and orderly approach to tasks, or a group of people who have formally come together.
Any of the prokaryotic organisms, such as an archaeon. Not in scientific use.
A very small cell
(Biology) The series of mitotic cell divisions by which a single fertilized egg cell becomes a many-celled blastula. Each division produces cells half the size of the parent cell.
The scientific study of the formation, structure, and function of cells.
(Anatomy) A membranous tissue composed of one or more layers of cells which forms the covering of most internal and external surfaces of the body and its organs: internally including the lining of vessels and other small cavities, and externally being the skin.
A process of asexual reproduction in which a single cell splits to form two identical, independent cells. In fission, the chromosomal DNA replicates before the cell divides. Most bacteria and other prokaryotes reproduce by means of fission.
A confinement facility whose inmates are individuals awaiting trial or convicted of lesser offenses.
That within which, or within and from which, something originates, takes form, or develops
The process in cell division in sexually reproducing organisms that reduces the number of chromosomes from diploid to haploid (half the original number). Meiosis involves two consecutive divisions of the nucleus and leads to the production of reproductive cells (gametes) in animals and to the formation of spores in plants, fungi, and most algae (the haploid spores grow into organisms that produce gametes by mitosis). Meiosis begins when the chromosomes, which have already duplicated, condense along the center of the nucleus, and pairs of homologous chromosomes undergo crossing over , whereby some of their genetic material is exchanged. The pairs of chromosomes then separate and move to opposite ends of the cell, and the cell itself divides into two cells. In the second stage, each of these two cells also divides into two cells. Meiosis thus produces four cells, each of which contain half the number of chromosomes as the original cell. Some or all of the four cells may become functional gametes or spores.
Mitosis is the process of dividing a cell and its nucleus into two cells which each have their own nucleus.
A concealed dungeon having a trap door in the ceiling as its only opening
The mature female gamete of an animal; an egg.
The definition of a prison is a building comprised of different cells or locked rooms designed to house prisoners who are sentenced to a correctional institution for breaking laws.
A semifluid, viscous, translucent colloid, the essential living matter of all animal and plant cells: it consists largely of water, proteins, lipids, carbohydrates, and inorganic salts and is differentiated into nucleoplasm and cytoplasm
A dividing or being divided into segments
The mature male gamete of an animal, usually consisting of a nucleate head, a short neck, and a thin motile tail.
A single person, group, or thing, esp. as distinguished from others or as part of a whole
Anything like a web, as in intricacy of pattern or interconnection of elements; network
The basic unit of living matter in all organisms, consisting of protoplasm enclosed within a cell membrane. All cells except bacterial cells have a distinct nucleus that contains the cell's DNA as well as other structures (called organelles) that include mitochondria, the endoplasmic reticulum, and vacuoles. The main source of energy for all of a cell's biological processes is ATP.
Any of various devices, or units within such devices, that are capable of converting some form of energy into electricity. Cells contain two electrodes and an electrolyte.
A device, such as a battery, that is capable of changing some form of energy, such as chemical energy or radiant energy, into electricity. &diamf3; An electric cell that converts light energy into electrical energy using the photoelectric effect is called a photoelectric or photovoltaic cell ; such cells are used in the generation of solar power and are called solar cells .
