membranes. Usually they are rod-shaped, however they can be
round. The outer membrane limits the organelle. The inner
membrane is thrown into folds or shelves that project inward.
These are called "cristae mitochondriales".  Chloroplasts are
specialized organelles found in all higher plant cells. These
organelles contain the plant cell's chlorophyll, hence provide
the green color. Chloroplasts capture light energy to conserve
free energy in the form of ATP and reduce NADP to NADPH through
a complex set of processes called photosynthesis.  Ribosomes are
minute particles composed of pr
