Two plants A and B are supplied with CO2 with H2O18 and CO218 with H2O respectively. Which following plant releases O18 type oxygen in photosynthesis?
During photosynthesis O2 evolved by the hydrolysis of water. If H2 O18 is used in 'A' plant then it become true that O18 type oxygen evolved from 'A' plant during photosynthesis.
If you consider the combined processes of photosynthesis and cellular respiration, the electrons found in H2 O at the beginning of the light reactions end up attaching to _______ during respiration.
The correct sequence of cell organelles during photorespiration is :
A process that makes important difference between C3 and C4 plants is :
Photorespiration is absent is C4 plants. Photorespiration does not produce energy or reducing power. Rather, it consumes energy. There is 25% loss of fixed CO2.Therefore, photorespiration is a highly wasteful process.This happens only in case of C3 plants.
CAM helps the plants in :
CAM plants are most common in arid environments.Being able to keep stomata closed during the hottest and driest part of the day reduces the loss of water through evapotranspiration
Of the total incident solar radiation the proportion of PAR is:
Out of total incident solar radiation, about 50% of it forms Photosynthetically Active Radiation(PAR).
Photosynthesis is
PGA as the first CO2 fixation product was discovered in photosynthesis of :
Phosphoglyceric and (PGA) is the first stable product of photosynthesis. It was first discovered by Calvin, Benson and their colleagues in Chlorella, algae.
Cyclic photophosphorylation results in the formation of
Cyclic photophosphorylation results in the formation of ATP.This process is called photophosphorylation, which occurs in two different ways. Adenosine triphosphate(ATP) is considered by biologists to be the energy currency of life. It is the high-energy molecule that stores the energy we need to do just about everything we do. It is present in the cytoplasm and nucleoplasm of every cell, and essentially all the physiological mechanisms that require energy for operation obtain it directly from the stored ATP.
Oxygenic photosynthesis occurs in:
Oxygenic photosynthesis occurs in Oscillatoria.Oscillatoria is a genus of filamentous cyanobacteria which is named for the oscillation in its movement.
