Answers
Answer:
Chlorophyll a is a specific form of chlorophyll used in oxygenic photosynthesis. It absorbs most energy from wavelengths of violet-blue and orange-red light, and it is a poor absorber of green and near-green portions of the spectrum.[3] Chlorophyll does not reflect light but chlorophyll-containing tissues appear green because green light, diffusively reflected by structures like cell walls, becomes enriched in the reflected light.[4] This photosynthetic pigment is essential for photosynthesis in eukaryotes, cyanobacteria and prochlorophytes because of its role as primary electron donor in the electron transport chain.[5] Chlorophyll a also transfers resonance energy in the antenna complex, ending in the reaction center where specific chlorophylls P680 and P700 are located.[6]
It is a part of the ring structure of chlorophyll. A non-ionic magnesium is held in the centre of porphyrin head by nitrogen atoms of pyrrole rings. Mg is also responsible for the maintenance of ribosome structure. Ribosome has two subunits.
Answer:
The screw gauge is an instrument used for measuring exactly the diameter of a thin wire or the width of a sheet of metal.Having a U shaped metallic mount, a screw gauge measures even the tiniest length with exact accuracy.
