Explain why phospholipids spontaneously form a bilayer when mixed with water?

Phospholipids form a bilayer when mixed with water, since the hydrophilic head is attracted to water, while the hydrophobic tails reject water and tend to aggregate with other hydrophobic molecules, this conflict is resolved with the formation of a lipid bilayer , which satisfies both parties.

They are those that have phosphoric acid in their composition, they are usually amphipathic: their molecules have a part that is soluble in water (that is, hydrophilic) and another that is not (hydrophobic).

Therefore, we can conclude that phospholipids are found in the active membranes of cells whose distinctive feature is they are usually amphipathic.

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
