Chlorophyll A green pigment located in membranes within the chloroplasts of plants and algae and in the membranes of certain prokaryotes. Chloroplast is an organelle found in the leaves of green plants. Plants that receive less sunlight have more chlorophyll B in their chloroplasts. The high energy electron enters an electron transport chain. C. The level of the liquid in the volumeter would remain constant since gas is neither being produced nor being used. For a majority of organisms capable of photosynthesis (plants, cyanobacteria, algae) chlorophyll a is the primary pigment of photosynthesis. The electron used in this process continues along the ETC to eventually aid in the production of NADPH. When you reach out to him or her, you will need the page title, URL, and the date you accessed the resource. Tube C The molecular formula of chlorophyll is C55H72MgN4O5.

A student set up an experiment where pieces of Elodea plant were placed in different test tubes and sodium bicarbonate solution was added. NADPH is an electron carrier that accepts a pair of high-energy electrons and transfers them, along with most of their energy, to another molecule. Function of Chloroplasts They are responsible to carry out photosynthesis, the process of conversion of light energy into sugar and other organic molecules that are used by plants or algae as food. Animals that eat plants or other animals are called heterotrophs. The chloroplast is a plant cell organelle that participates in photosynthesis.
