How do you compare the different roles of photosystem 1 and photosystem 2 in photosynthesis?
The structure of photosystem I in a cyanobacterium ("blue-green alga") has been completely worked out. It probably closely resembles that of plants as well. It is a homotrimer with each subunit in the trimer containing: * 12 different protein molecules bound to * 96 molecules of chlorophyll a ** 2 molecules of the reaction center chlorophyll P700 ** 4 accessory molecules closely associated with them ** 90 molecules that serve as antenna pigments * 22 carotenoid molecules * 4 lipid molecules * 3 clusters of Fe4S4 * 2 phylloquinones Photosystem II is also a complex of * > 20 different protein molecules bound to * 50 or more chlorophyll a molecules ** 2 molecules of the reaction center chlorophyll P680 ** 2 accessory molecules close to them ** 2 molecules of pheophytin (chlorophyll without the Mg++) ** the remaining molecules of chlorophyll a serve as antenna pigments. * some half dozen carotenoid molecules. These also serve as antenna pigments. * 2 molecules of plastoquinone

What is water roles in the light reaction of photosynthesis?
Water is essential in the light reaction of photosynthesis as it serves as a source of electrons for photosystem II to replace those lost during electron transport. When water molecules are split in a process known as photolysis, oxygen is released, and electrons are transferred to chlorophyll in the photosystem, which initiates the electron transport chain.
Compare the following palisade and spongy mesophylls how do their structural features help them perform their specific roles in the process of food manufacture?
Palisade mesophyll cells are tightly packed, contain many chloroplasts, and are located near the upper leaf surface to maximize light absorption for photosynthesis. Spongy mesophyll cells have air spaces between them to facilitate gas exchange, allowing for efficient transport of gases needed for photosynthesis. The structural features of both cell types are adapted to their specific roles in photosynthesis - palisade mesophyll for light capture and spongy mesophyll for gas exchange.
What are the roles of chloroplast and chlorophyll in photosynthesis?
The role of chlorophyll in photosynthesis is the absorption of light allowing the plant to obtain energy from the light. Chloroplasts are the organelles in the plant that store the chlorophyll.
The two main roles of protists are?
The two main roles of protists are as primary producers in aquatic ecosystems through photosynthesis, and as decomposers that recycle nutrients in various environments.
Do lysosome specifically work with photosynthesis?
No, lysosomes do not specifically work with photosynthesis. Lysosomes are membrane-bound organelles found in animal cells that contain enzymes for digesting macromolecules and recycling cellular waste. Photosynthesis, on the other hand, occurs in chloroplasts, which are found in plant cells and some algae, where they convert light energy into chemical energy. While both organelles are essential for cellular function, they play distinct roles in different processes.

Are the chlorophyll molecules in PSI and PSII the same?
No, the chlorophyll molecules in Photosystem I (PSI) and Photosystem II (PSII) are not the same. They differ in absorption spectra and redox properties, allowing them to play distinct roles in the light reactions of photosynthesis.

Chlorophyll a and b are found in a specific photosystems which photosystem contains chlorophyll a and which contains chlorophyll b?
I have studied photosyn. and to the best of my knowledge chl. a and b are in both photosystems. The difference between absorption in photosystem II (p680) and I (p700) is caused by the amount of a (best at 450-500nm) or b (best at 470-600nm).Photosyn. I should have more b and photosyn. should have more a.

Who is the best soccer player in wolfsburg?
This question is unanswerable because it depends on many different things. Also, it is impossible to compare a... defender to a striker/forward because of the different roles they play. Players have different strengths and weaknesses sometimes depending on the position they play.
What are the roles of oxygen and carbonn dioxide in cell repiration and photosynthesis?
in photosynthesis carbon dioxide is used with water and light energy from the sun to create glucose (plant food).
