The primary structural component of a cell membrane is?
phospholipids. They form a lipid bilayer that surrounds the cell, providing a barrier that controls what enters and exits the cell. Additionally, proteins embedded in the phospholipid bilayer play a crucial role in facilitating various cellular processes.
How do water molecules and small ions enter a cell?
Some water molecules and small ions ( depending on charge, other ions need passive or active transport ) can diffuse across the cell's membrane and there are channels called porins that facilitate water molecule passage into the cell.
Compare and contrast the cell wall and cell membrane?
A cell membrane or plasma membrane is present in a plant cell and an animal cell. The Cell wall is a layer much thicker than the cell membrane present in plant cells only and the cell wall gives the plant cell it shape unlike in a animal cell,animal cells are irregularly shaped.
Why is it necessary to have a cell membrane on a plant cell?
The cell surface membrane is partially permeable membrance that is made up of double phospholid layers comprising of 1. lipids 2. fats 3. proteins 4. phosphate groups. This is therefore needed for the control of substances in and out of the cells (: margaret
What is the meaning of the word phospholid?
It seems like there may be a typo in your question. The correct term is phospholipid, which is a type of lipid molecule that is a major component of cell membranes. They have a hydrophilic (water-attracting) head and hydrophobic (water-repelling) tails, allowing them to form a lipid bilayer that surrounds cells.
What bond occurs in a phospholid?
Phospholipids are amphipathic molecules with two hydrophobic fatty acids and a hydrophilic phosphate-containing group linked to glycerol. When placed in an aqueous solution, water forms a shell around the hydrophobic lipid, a situation that not only prevents water from making hydrogen bonds with other water molecules, but also reduces freedom of movement, making the water molecules more ordered.

What is the key structural element of a cell membrane?
The primary structural component of a cell membrane is the phospholid layers. This is mainly made of proteins which facilitate various cell activities.
