Nutrition in Plants: Photosynthesis, Autotrophic Nutrition, Videos . . . The Process of Photosynthesis in Autotrophs Plants To put it simply, plants require certain raw materials, in order to make their own food These raw materials include carbon dioxide, water, and sunlight Plants get water from the soil that enters through the roots And sunlight is the source of energy But how does carbon dioxide enter the plants?
In a measurement of quantum efficiency of photosynthesis in . . . - Toppr Q 1 In a measurement of quantum efficiency of photosynthesis in green plants, it was found that 10 quanta of red light of wavelength 6850 ˚A were needed to release one molecule of O2 The average energy storage in this process is 112kcal per mol of O2 evolved What is the energy conversion efficiency in this experiment?
Can you explain why twelve molecules of water as substrate are . . . - Toppr 6CO2 +12H 2O Light → C6H 12O6 +6H 2O+6O2 where C6H 12O6 represents glucose The O2 released is from water; this was proved using radio isotope techniques Note that this is not a single reaction but description of a multistep process called photosynthesis Can you explain why twelve molecules of water as substrate are used in the equation given?
Explain the C_ {4} cycle of photosynthesis. - Toppr This pathway mostly takes place in monocot plants and in some dicot plants In this pathway, the first product of CO22fixation is a 4 carbon compound, oxaloacetic acid, hence it is called C44 pathway The anatomy of leaves of C44 plants is different from leaves of C33 plants (Calvin cycle) Palisade cells in the mesophyll tissues are absent There is bundle sheath around the vascular bundles
Rate of photosynthesis is maximum inYellow lightBlue . . . - Toppr So that, the rate of photosynthesis is maximum in red and blue light of the visible spectrum Minimum photosynthesis takes place in the green light Minimum absorption of chlorophyll a occurs in the green region because plants themselves are green due to the pigment Chlorophyll Was this answer helpful?
How many ATP and NADPH + H+ are required the synthesis of 1 . . . - Toppr The correct option is B 18ATP, 12NADPH and 30ATP ,12NADPH In C 3 pathway in Calvin cycle, one CO 2 molecule require 3ATP and 2 NADPH and as the cycle turn to be six times for the formation of one glucose molecule 18 ATP and 12 NADPH are required while in C 4 plant one CO 2 molecule needs 5 ATP molecule as the process occurs in mesophyll cells to bundle sheath cells and came back to mesophyll
Which factor is not limiting in normal conditions for photosynthesis? According to limiting factors of photosynthesis, chlorophyll is not counted in normal conditions It is because chlorophyll is a pigment, which is present in plants and not an external factor It is involved in the trapping of light for the light dependant reaction of photosynthesis Chlorophyll pigments do not determine the rate of photosynthesis
Difference between Endothermic and Exothermic Reactions - Toppr Photosynthesis is a popular example of an endothermic chemical reaction During this process, plants absorb energy from the Sun One popular example of an exothermic reaction is the chemical reaction between sodium and chlorine, which results in common salt i e sodium chloride
