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.
Proteins and lipids don't have cell membranes but are the molecules that make up the bulk of what a cell membrane is.
Molecular transport refers to the movement of individual molecules across cell membranes, often through processes like diffusion or facilitated diffusion, which occur at a cellular level. In contrast, bulk transport involves the movement of larger quantities of materials, such as groups of molecules or particles, typically through processes like endocytosis and exocytosis. While molecular transport is generally passive and driven by concentration gradients, bulk transport often requires energy input to move substances across membranes.
The bulk of an animal cell is formed by the cytoplasm, which is a jelly-like substance that fills the cell and contains various organelles like the nucleus, mitochondria, endoplasmic reticulum, and Golgi apparatus. The cytoplasm is where many cellular processes take place, such as metabolism, protein synthesis, and transportation of molecules within the cell.
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.
The bulk density of magnetite can be calculated using the formula: Bulk Density = (mass of material) / (volume of material). This formula involves measuring the mass of the magnetite sample and calculating its volume to determine the bulk density.

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).

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.

The material bulk of the nail is primarily composed of a protein called keratin, which is a fibrous structural protein also found in hair and skin. Nails also contain a small amount of water and lipids that help maintain their health and flexibility. Additionally, the nail plate is formed from tightly packed cells that undergo keratinization, contributing to its hardness and durability.
