Biology Chapter 5, Lesson 1 Notes
... Phospholipids are lipid molecules that have a head and a tail. The tail or fatty acid end of a phospholipid molecule is hydrophobic (water hating) and carries a neutral charge and is nonpolar. The tails keep water from rushing into the cell, that could cause the cell to burst. The head of a ph ...

Thylakoid
A thylakoid is a membrane-bound compartment inside chloroplasts and cyanobacteria. They are the site of the light-dependent reactions of photosynthesis. Thylakoids consist of a thylakoid membrane surrounding a thylakoid lumen. Chloroplast thylakoids frequently form stacks of disks referred to as grana (singular: granum). Grana are connected by intergranal or stroma thylakoids, which join granum stacks together as a single functional compartment.
