What is the function of the endoplasmic reticulum in a cell?

• Storage of genetic material

• Protein and lipid synthesis, and transportation of molecules within the cell

• Energy production through photosynthesis

• Regulation of cell division

Describe the structure of the cell membrane and its function.

• The cell membrane is a single layer of protein and its function is to produce hormones

• The cell membrane is composed of DNA and its function is to provide color to the cell

• The cell membrane is made of carbohydrates and its function is to store energy

• The cell membrane is composed of a phospholipid bilayer with embedded proteins. Its function is to regulate the movement of substances in and out of the cell, and to provide structural support.

Explain the role of phospholipids in the cell membrane.

• Phospholipids help form the structure of the cell membrane and regulate the movement of molecules in and out of the cell.

• Phospholipids are only found in the nucleus of the cell

• Phospholipids have no role in the cell membrane

• Phospholipids are responsible for energy production in the cell membrane

Explain the process of osmosis and its significance in cellular function.

• Osmosis is the movement of water molecules from an area of higher solute concentration to an area of lower solute concentration

• Osmosis is the movement of water molecules across a semi-permeable membrane from an area of lower solute concentration to an area of higher solute concentration. It is significant in cellular function as it helps in maintaining the balance of water and solutes inside the cell, allowing for proper cell function and maintaining cell shape.

• Osmosis has no significance in cellular function

• Osmosis is the movement of air molecules across a semi-permeable membrane
