Biology - Photosynthesis
Euglena: contains chloroplasts
Photosynthesis  takes place in the chloroplasts of photosynthetic
cells and in cyanobacteria (formerly called blue-green algae).
Photosynthesis does occur in animal cells.
Photosynthesis transforms light energy (red and blue wavelengths) into
chemical energy stored in molecules.
Plants have the amazing ability to be able to take in inorganic compounds
through their roots and leaves (water and carbon dioxide) and, through a
series of chemical reactions, convert them into organic compounds such as
Animals can't make their own food. They need to consume other living
things to get the organic compounds they need for energy. So plants are
incredible living things because they are a source of food for the whole
Photosynthesis actually involves over fifty small chemical reactions. It
would be ridiculous for you to learn all of these reactions. The overall
process can be divided into main stages:
* The light phase (photolysis)
* The light-independent phase (also called dark phase/reactions or
