The intracellular membrane system of a eukaryotic cell, comprising the endoplasmic reticulum, the Golgi apparatus, lysosomes and the plasma membrane. These membrane systems are interconnected by a flow of membrane from one to another using small membrane vesicles. ARTIFICIAL NEURAL NETWORK (ANN). An ...
(ii) All bio membranes are either made of a unit membrane or a multiple of unit membrane. The unit membrane of Robertson is also called trailaminar membrane. It has a thickness of about 75 Å with a central lipid layer of 35 A thick and two peripheral protein layers of 20Aeach. Ac...

Plant-specific aspects of membrane biology are reviewed by international experts in the field. The 31 chapters are grouped into 6 main subject areas: membranes and the cell surface (9 chapters discussing the specialized functions of the plant plasma membrane within its cellular context); membrane li...
Cholesterol-Rich Plasma Membrane Domains (Lipid Rafts) in Keratinocytes: Importance in the Baseline and UVA-Induced Generation of Reactive Oxygen Species The biologic effects of ultraviolet radiation such as DNA damage, mutagenesis, cellular aging, and carcinogenesis are in part mediated by reactive oxyg...
The specialized peloton in the intracellular spaces of cortical tissues in the embryo or in developed roots of orchids is surrounded by an extension of the plasma membrane of orchid cell. At the cellular interface between the orchid and fungi, orchids are thought to control hyphal growth by ...
The plant cell deposits its wall as a series of layers. The earliest layers are deposited at cell division, and the cell then lays down further material between the plasma membrane and the earlier layers. Thus the first-formed material is found at the point where the cell wall adjoins the...
Membrane, in biology, the thin layer that forms the outer boundary of a living cell or of an internal cell compartment.
