What is Photosynthesis? Photosynthesis definition:Photosynthesisis a physio-chemical process carried out byphoto-auto-lithotrophs. In simpler language, photosynthesis is the process by which green plants convert
What is the result of meiosis 1 (including cytokinesis 1)? What is the result of meiosis 2? What is respiration? Does catabolism include cellular respiration in its definition? Explain how nutrients are converted into energy. Explain how Pyruvate oxidation and the citric acid cycle ...
The photochemical step of photosynthesis consists of what are called light-dependent reactions that occur within the chloroplasts. During this step, light energy is absorbed by pigments within the chloroplast and used to produce a high-energy compound (adenosine triphosphate, ATP) and a strong reducin...
Here, six molecules of carbon dioxide (CO2) combine with 12 molecules of water (H2O) using light energy. The end result is the formation of a single carbohydrate molecule (C6H12O6, or glucose) along with six molecules each of oxygen and water. Similarly, the various anoxygenic photosynthesis r...
Many of these carbohydrates are produced by photosynthesis, the biochemical process by which phototrophic organisms convert solar energy (sunlight) into chemical energy. Although photosynthesis is most commonly associated with plants, microbial photosynthesis is also a significant supplier of chemical energy,...
The veins in a plant that pull water from the soil are called xylem. Chlorophyll is the green pigment in a plant's leaves. Chlorophyll is what traps the sun's energy. Carbon dioxide passes into the plant's leaves through small pores called stomata. The energy absorbed by the chlorophy...
C4 Plants C4 plants have 2 enzymes (PEP carboxylase & rubisco) for CO2 fixation in 2 different parts of the leaf. PEP carboxylase does not have an affinity for O2 and fixes CO2 even at very low CO2 levels. What is the significance of this fact? C4 plants include sugarcane, corn and ot...
Plants, algae and cyanobacteria use a chemical reaction known as photosynthesis to create the materials they need from what’s around them. Plucking carbon dioxide from the air, water from the ground and light from the sun, land plants make sugar and kic
Synthetic photosynthesis will convert CO 2 and water into energy rich carbon compounds and oxygen, mimicking what happens in Nature, without repeating the natural process that occurs in leafs. The man-made device that will support such C-cycling is constituted of several parts such as: antennae ...
On Earth, solar radiation can transmit down to multiple metres within ice, depending on its optical properties. Organisms within ice can harness energy from photosynthetically active radiation while being protected from damaging ultraviolet radiation. On
