The cell membrane is a lipid bilayer, composed of phopholipids: A glyerol molecule with two fatty-acid groups at one end and a phosphate group at the other.Phospholipids are synthesised in the cytoplasm next to the endoplasmic reticulum. The ER sythesthies the lipids, and contains enzymes that catalyse the production of phopholipids such as Glycerol-3-phosphate acyltransferase.
The phospholipids produced migrate naturally to the internal face of the membrane, and flippase moves them to the outer face.
The Smooth Endoplasmic Reticulum :)
Proteins and lipids don't have cell membranes but are the molecules that make up the bulk of what a cell membrane is.
Cytoplasm... I believe
The bulk of cellular membranes are made of lipids, which keep materials from moving in either direction, while there are proteins stuck in at irregular intervals that selectively allow materials to move in and out.
Bulk phenomenon refers to the phenomenon where whole of the substance or object is involved in the process and is affected in bulk completely. For e.g boiling.
Endocytosis is the bulk transport of materials into a cell, using energy in the form of ATP. It is an active process, and the energy is used to move the membranes around the materials to form the vesicles that are needed, and to move the vesicles into the cell.

diffusion through the membranes bulk flow transport via vesicles or caveolae
Mainly lipids and protein make up the cell wall, Lipids are just a fancy word for fat. Hope this helped. All i care a bouts money, my excuse is that I'm young, and I'm only getting older
Lipids are created in the smooth endoplasmic reticulum of a cell. Many are used in the cell membrane, particularly phospholipids, whose double layer creates the basic structure of the membrane.
I'm actually doing that for my science organelle project. A leucoplast is a colorless organelle found in plant cells usually used to important biosynthetic functions as well as bulk storage. There are 4 different types of leucoplasts: amyloplast, elaioplast, and proteinoplasts. Within amyloplasts, there is a gravity- supplying plastid called a statolith. Next time, go Wiki (Wikipedia).

What is bulk polymerization?

Bulk mailbroadly refers to mail that is mailed and processed in bulk at reduced rates.
Please clarify your question. As in, the bulk of what?
