First of all, chlorophyll is NOT an enzyme. Enzymes are proteins. Chlorophyll is not a protein nor is it constructed of amino acids. It is a pigment and has a pretty simple structure compared to proteins. It's fairly easy to find it's structure in college textbooks or on the internet.
Functionally, some people think it is like an enzyme because they think it is a catalyst. Working in concert with other substances including true enzymes and other proteins, the combination could be considered a catalyst for a specific step in photosynthesis. Chlorophyll is able to absorb photons of light energy and pass that energy along in the form of a high energy electron. In the process, it also works with other substances in the chloroplast (specifically in the thylakoid membrane) to break water apart to make O2 (oxygen gas) and H+ ions. This is the only step in the longer process of photosynthesis that involves chlorophyll.
To say chlorophyll alone is a catalyst is wrong. To say it catalyzes photosynthesis is a gross oversimplification of a complex process whose details are well known.
yes,and the chlorophyll is just one of the conmponents that act to obtain energy. Dark phase of photosynthesis does not need chlorophyll but it does need the chlroplast for several enzymes to assimilate carbondioxide.
Enzymes are catalysts because they supply energy. However, there can be other forms of catalysts. During photosynthesis, oxygen is the catalyst for the reaction.
Magnesium is needed by plants to make the green pigment chlorophyll and to activate some enzymes. Although there may appear to be a lot of chlorophyll in plants, each chlorophyll molecule only contains one magnesium atom. The molecular weight of chlorophyll (in fact, chlorophyll a) is 893.5. The atomic weight of magnesium is 24.3. So magnesium only makes up about 2.7% of the weight of the chlorophyll. Enzymes are catalysts and are only needed in small amounts to catalyse reactions, as they are used over and over again, so only small amounts of magnesium are needed. http://www.efma.org/introduction/section01.asp
water, carbon dioxide, chlorophyll and enzymes
Most Autotrophs possess chlorophyll to capture light and prepare food . Some autotrophs are chemosynthetic which possess enzymes for redox reaction and get energy from chemicals .

Chlorophyll pigments are needed with enzymes. Water and CO2 needed as raw materials.
Enzymes,ribosomes,some organic materials,thylakoid membranes.Most importantly,chlorophyll.
