Chlorophyll definition a level biology
WebChlorophyll A and B. For a majority of organisms capable of photosynthesis (plants, cyanobacteria, algae) chlorophyll a is the primary pigment of photosynthesis. It's responsible for absorbing light in the orange to red and violet to blue spectrum that provides the energy required for subsequent photosynthetic reactions. WebChloroplasts are the organelles in plant cells where photosynthesis occurs Each chloroplast is surrounded by a double-membrane envelope Each of the envelope membranes is a phospholipid bilayer Chloroplasts are filled with a fluid known as the stroma The stroma is the site of the light-independent stage of photosynthesis

WebReactions. Light-dependent reactions are the energy conservation phase of photosynthesis. The ultimate aim of these reactions is to convert light energy from the sun into chemical energy that can be utilized to make glucose during dark reactions. The chemical energy is obtained in the form of two high energy metabolites; ATP and NADPH.
