Relationships      
Parents BodyPart 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 CellInternalMembraneGroupThe class of groups of internal cell membranes contained within each cell.
 CellMembraneThe class of cell membranes, internal and external.
 CellNucleusThe part of the Cell that contains DNA and RNA.
 CellWallA 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]
 ChromotinThe class of chromotin found in cell nucleuses.
 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.
 HydrophilicSideThe class of hydrophilic sides of lipid bilayers.
 HydrophobicSideThe class of hydrophobic sides of lipid bilayers.
 LipidBilayerThis is the class of lipid bilayers that surround cells and make up a substantial portion of a cell membrane.
 ProteinSynthesisToolThe class of parts in a cell that are used in the translation and transcription of the cell's genetic information.
