Question

with items from this list. each item will be used once. passive diffusion transport permeability head proteins osmosis exocytosis energy the hydrophilic of the phospholipid is attracted to water, while the hydrophobic tail repels it. transport proteins play a crucial role, allowing specific molecules to across the membrane. some molecules like oxygen and carbon dioxide can move through the cell membrane by the process of simple larger molecules like glucose require the assistance of transport to pass through the membrane. is the movement of water molecules across a selectively permeable membrane. molecules moving from an area of high concentration to low concentration without the need for energy is known as transport. active transport requires from the cell and moves substances against their concentration gradient. endocytosis and are processes involving vesicles to transport larger quantities or particles. the selective of the cell membrane ensures that the internal environment of the cell remains stable.

Explanation:

1. Phospholipids have a hydrophilic head and hydrophobic tail. The head is attracted to water.
2. Transport proteins help molecules transport across the membrane.
3. Small molecules like oxygen and carbon - dioxide move by diffusion.
4. Larger molecules like glucose need transport proteins to cross the membrane.
5. Osmosis is the movement of water across a selectively permeable membrane.
6. Passive transport is when molecules move from high to low concentration without energy.
7. Active transport requires energy from the cell.
8. Exocytosis and endocytosis are vesicle - based transport processes.
9. The selective permeability of the cell membrane maintains cell stability.
