Question

1. blocks ot ers. what two things make up a phospholipid? ____ ____
2. draw a picture of the phospholipid bilayer sheet below and label the head & tails

Explanation:

A phospholipid is composed of two main parts: a hydrophilic (water - attracting) phosphate - containing "head" group and two hydrophobic (water - repelling) fatty acid "tails". The head region is polar and the tails are non - polar. This structure is crucial for the formation of cell membranes as the heads face the aqueous environments (inside and outside the cell) and the tails face each other, forming a bilayer.

Answer:

A phospholipid is made up of a hydrophilic phosphate - containing head group and two hydrophobic fatty acid tails.
