Cell membrane review

All living cells are surrounded by a very thin membrane that is called....

• Cell wall

• Nucleus

• Cell surface membrane

• Endoplasmic Reticulum

Cell membranes are made up of all of the following materials except:

• Lipid

• Carbohydrates

• Protein

• Mineral

The cell membrane is

• single layer

• bilayer

• triple layer

• helix layer

The cell Membranes have several important functions except

• controls the exchange of materials such as nutrients and waste products between the cell and its environment.

• regulation of transport across the membranes of organelles

• enable cells to receive hormone messages and in chloroplasts they contain the light-absorbing pigments needed for photosynthesis.

• fight bacteria and viruses that enter the cell.

Phospholipids help to form the membranes that surround cells and organelles. The head of the phospilipids are ...... and it always face the water

Meanwhile the tails of Phospolipids are

membranes also contain protein. There are two types of protein. what are they?

Proteins are contained of carbohydrates from the group of

• Polysaccharides

• oligosaccharides

• Monosaccharides

• Disaccharides

These are the molecules that contained inside the membrane except

• Phospholipids

• Cholesterol

• Glycolipid & Glycoprotein

• Vitamin

The molecular mechanisms by which cells detect and respond to external stimuli, including communication between cells is called

• Cell signaling

• Cel Diffusion

• Cell Division

• Cell Absorption
