Question

the cell membrane is made of phospholipids. take a look at the structure of a phospholipid.
what does the term hydrophilic mean?
what does the term hydrophobic mean?
these phospholipids form whats referred to as a phospholipid bilayer, where the hydrophilic heads face the water that surrounds the cell and the hydrophobic tails are away from water that surrounds the cell. the phospholipid bilayer of the cell membrane is described as a fluid mosaic model because of the way that it is shaped.
take a look at the phospholipid bilayer in the image to the left. then, turn the page to dig deeper into the molecules that can be found within the cells membrane.

Explanation:

Hydrophilic means having an affinity for water (water - loving). Hydrophobic means having a lack of affinity for water (water - hating).

Answer:

Hydrophilic: Having an affinity for water (water - loving). Hydrophobic: Having a lack of affinity for water (water - hating).
