...ganelles able to produce oxygen. Plastids, such as chloroplasts found in plants, evolved around 1,500 million years ago. During the following 500 million years, organisms that contained up to 50 different cell types evolved. These more complex organisms included algae, which would have benefited directly from bei...First company founded on UCF biotechnology formed

Plant plastids are the site for many essential biochemical functions,including the synthesis of compounds necessary for life such as certain aminoacids and folate, which animals get from eating plants.
