Relationships      
Parents body part A collection of Cells and Tissues which are localized to a specific area of an Organism and which are not pathological. The instances of this Class range from gross structures to small components of complex Organs.
Children cell internal membrane groupThe class of groups of internal cell membranes contained within each cell.
 cell membraneThe class of cell membranes, internal and external.
 cell nucleusThe part of the Cell that contains DNA and RNA.
 cell wallA cell wall is a structural layer surrounding some types of Cells, just outside the CellMembrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism. Cell walls are present in most prokaryotes (ProkaryoticCell) (except a mollicute Bacterium), in algae (Alga), fungi (Fungus) and (EukaryoticCell) including Plants but are absent in Animals. A major function is to act as pressure vessels, preventing over-expansion of the cell when Water enters. The composition of cell walls varies between species and may depend on cell type and developmental stage. The primary cell wall of land plants is composed of the polysaccharides cellulose, hemicelluloses and pectin. Often, other polymers such as lignin, suberin or cutin are anchored to or embedded in plant cell walls. Algae possess cell walls made of glycoproteins and polysaccharides such as carrageenan and agar that are absent from land plants. In bacteria, the cell wall is composed of peptidoglycan. The cell walls of (ArchaealCell) have various compositions, and may be formed of glycoprotein S-layers, pseudopeptidoglycan, or polysaccharides. Fungi possess cell walls made of the N-acetylglucosamine polymer chitin. Unusually, diatoms have a cell wall composed of biogenic silica. [from Wikipedia]
 ChromosomeA Chromosome is the structure of a cell's genetic material in the form of multiple linear DNA molecules, called Chromotin, forming the majority of the cell nucleus. [Wikipedia]
 chromotinThe class of chromotin found in cell nucleuses of eukaryota.
 cytoplasmThe material in a cell that is outside of the nucleus and inside the cell's outer membrane.
 cytoskeletonThe class of cytoskeletons found in cells.
 endomembraneThe class of cellular endomembranes.
 hydrophilic sideThe class of hydrophilic sides of lipid bilayers.
 hydrophobic sideThe class of hydrophobic sides of lipid bilayers.
 lipid bilayerThis is the class of lipid bilayers that surround cells and make up a substantial portion of a cell membrane.
 NucleosomeA Nnucleosome is the fundamental subunit of Chromatin. It is the basic structural unit of DNA packaging in eukaryotes. The structure of a nucleosome consists of a segment of DNA wound around eight Histone proteins and resembles thread wrapped around a spool. [Wikipedia]
 protein synthesis toolThe class of parts in a cell that are used in the translation and transcription of the cell's genetic information.
