Are organelles (akin to thinking of organs within a body) - membrane-bound
structures found within a cell whose main role is to conduct photosynthesis. In
photosynthesis, the pigment chlorophyll captures energy from sunlight and stores it
in energy storage molecules while freeing oxygen from water. See
Wikipedia
for

Colloids
Are substances in which microscropically dispersed insoluble particles are
suspended throughout another substance. Sub-types include aerosols (smoke), gels
(aerogel), emulsions (mayonannaise) and foams (shaving cream).
