complexes. Chlorophyll molecules use their energy to strip water molecules‚ and biological molecules then adding hydrogen to them. In prokaryotes instead of chloroplast they use their own cell membranes to do the job. Wavelength also has a role in photosynthesis because they have just the right amount of energy to excite chlorophyll electrons boosting them to a higher energy level. When summing everything up the reactants are carbon dioxide‚ water‚ and the suns energy and the process is light dependent

Photosynthesis The leaves are the part of a plant where most photosynthesis takes place. If you cut a leaf in half and look at the cut end‚ it would look like this: Key: 1. Waxy cuticle: this gives the leaf a waterproof layer‚ which lets in light. 2. Upper epidermis: provides an upper surface. 3. Palisade cells: contain chloroplasts. 4. Spongy mesophyll: collection of damp‚ loosely packed cells. 5. Lower epidermis: layer of cells on the lower surface. 6. Air

Separation of leaves pigment. Introduction The photosynthetic pigment is used to absorb light during the process of photosynthesis. There are five pigments usually found in spinach leaves: Carotene (yellow)‚ Phaeophytin (yellow-grey)‚ Xanthophyll (yellow-brown)‚ Chlorophyll a (blue-green)‚ Chlorophyll b(green). Photosynthetic pigment is located in the chloroplast of the leaf. The function of chlorophyll a and chlorophyll b is to trap red and blue violet light when they carry out photosynthesis‚ chlorophyll

Cellular Respiration and Photosynthesis Photosynthesis is the process by which plants‚ some bacteria‚ and some protistans use the energy from sunlight to produce sugar‚ which cellular respiration converts into ATP‚ the "fuel" used by all living things. The conversion of unusable sunlight energy into usable chemical energy‚ is associated with the actions of the green pigment chlorophyll. Most of the time‚ the photosynthetic process uses water and releases the oxygen. Cellular respiration

of ATP. Although both processes are found in double membraned organelles‚ photosynthesis occurs in chloroplasts in plant cells and cellular respiration occurs in the mitochondria of animal cells. Photosynthesis uses water and carbon dioxide as reactants to produce glucose and oxygen where as cellular respiration uses glucose and molecular oxygen as reactants to produce water‚ carbon dioxide‚ and energy (ATP). Photosynthesis is a two part process which includes photophosphorylation (light reactions)

The light reactions of photosynthesis contain two photosystems‚ two electron transport chains‚ and ATP synthase. These parts are embedded in the thylakoid membranes of a chloroplast. The photosystems contain a collection of chlorophyll molecules. Chlorophyll‚ which is the green pigment of leaves‚ absorbs light energy that excites electrons to a higher energy level. Energized electrons from photosystem I are passed down an electron transport chain and added to NADP+ to form NADPH. Electrons from photosystem

American chemist Dr. Daniel Nocera has devoted his career to finding this alternative energy source using photosynthesis as his inspiration. Photosynthesis‚ the conversion of solar energy into chemical energy stored in the bonds of glucose‚ is arguably one of the most important chemical reactions on earth. The maintenance of life on earth‚ our food‚ oxygen‚ and fossil fuels depend upon photosynthesis. In this process water and carbon dioxide are converted to oxygen and glucose using energy from the sun

How does photosynthesis impact the flow of energy and the cycling of nutrients‚ you ask? Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis provides the base for the one way flow of energy through the biosphere. Plants convert energy from the sun into sugars‚ which provide fuel for themselves and for other organisms. Photosynthesis also cycles carbon and oxygen nutrients through the
