Photosynthesis begins when a plant's chlorophyll in the chloroplasts capture energy from the sun. Water is taken up from the soil, and carbon dioxide enters the leaves through the stomates. The light energy is used to convert water and carbon dioxide into glucose, and oxygen is given off.Know More
The first part of photosynthesis is called the light dependent reaction. During this phase, light energy is captured and stored in a chemical called adenosine triphosphate, or ATP. The second phase, the light independent reaction, involves using the ATP to make glucose during the Calvin Cycle. When light gets to a plant, it does not use all of it. The plant absorbs mostly red and blue wavelengths. Although some of the glucose is used for respiration and some of it is converted into starch for storage, the stored starch can be used later for respiration and to make glucose.
Photosynthesis is a type of autotropic nutrition, meaning that the organism can make nutrients that it needs for energy and growth using materials from its environment. Photosynthesis allows certain organisms to make the energy from sunlight usable, because living things can eat glucose but not sunlight. Temperature, carbon dioxide levels and light intensity are factors that affect the rate of photosynthesis.Learn more in Molecular Biology & DNA
Gel electrophoresis is a process of separating bio molecules of different sizes by running them through a sievelike matrix using electricity. The larger molecules move more slowly, while smaller molecules slip through the matrix and move faster and farther, thus separating the different fragments based on size.Full Answer >
The "steps" or "rungs" of a DNA molecule are made up of four nucleobases, including adenine (A), cytosine (C), guanine (G) and thymine (T). These bases are arranged in particular pairs. A only bonds with T and vice versa, while C only pairs with G and vice versa.Full Answer >
The red and violet-blue light emitted from the sun are absorbed by the chlorophyll and used to drive most of photosynthesis. The green light is not absorbed and then reflected back which gives the leaves of plants their green color, according to the Central Michigan University.Full Answer >
The steps, or rungs, of the DNA ladder are made up of two bases joined together with either two or three weak hydrogen bonds. The rails of the ladder are made up of alternating sugar and phosphate molecules. The rungs are comprised of two bases between sugar molecules.Full Answer >
