organelle;
CHLOROPLASTS
contains inner stacks of
membrane and chlorophyll.
FUNCTION
OTHER
Converts solar energy Found in plants
and
some
bacteria
from the Sun into
chemical energy
analogous to
(glucose)
solar panels
MAKING LIPIDS
CELL PART
STRUCTURE
SMOOTH
ENDOPLASMIC
RETICULUM
Same as RER but lacks
ribosomes;
FUNCTION
OTHER
Manufactures lipids
Smooth = no ribosomes
analogous to churning
butter
STRUCTURE AND
SUPPORT
CELL PART
STRUCTURE
CELL WALL
Rigid outer boundary
surrounding cell
membrane.
FUNCTION
Protection; provides
shape and support
OTHER
Found in
plants and
bacteria!
analogous to
