Plant primitive plants lacking some tissue types. Plants are photosynthetic, which means that they manufacture their own food molecules using energy obtained from light. The primary mechanism plants have for capturing light energy is the pigment chlorophyll. All green plants contain two forms of chlorophyll, chlorophyll "a" and chlorophyll "b". The latter of these pigments is not found in red or brown algae. The simple equation of photosynthesis is as follows:- 6CO + 6HO → (in the presence of light and chlorophyll) CHO + 6O By means of cells that behave like nerves, plants receive and distribute within their systems information
Halobacteriales and assisting in the production of energy from light. The process is unrelated to other forms of photosynthesis involving electron transport; however, and halobacteria are incapable of fixing carbon from carbon dioxide. Halobacteria can exist in salty environments because although they are aerobes they have a separate and different way of creating energy through photosynthesis. Parts of the membranes of halobacteria are purplish in color. These parts conduct photosynthetic reactions with retinal pigment rather than chlorophyll. This allows them to create a proton gradient across the membrane of the cell which can be used to create ATP for their own
