How is the process of carbon fixation in CAM plants different from the process in C3 and C4 plants? a. CAM plants require a larg
Leya [2.2K]

Answer:

The correct answer would be option C.

Plants evolved different methods to prevent or reduce the effects of photorespiration.

The C3 plants are the most common plants which do not have any special methods or physiology to prevent photorespiration.

The C4 are the plants in which carbon fixation and the Calvin cycle takes place in different cells. Carbon is fixed in the mesophyll cells with the help of PEP carboxylase enzyme. It fixes carbon and converts PEP into oxaloacetate. The Calvin cycle takes place in the bundle-sheath cells.

In contrast, CAM (Crassulacean acid metabolism) plants are those in which carbon fixation and Calvin cycle are separated into time. The carbon is fixed during the night as it helps in reducing the loss of water through transpiration.

The Calvin cycle takes place during the day time in the same cell, that is, mesophyll cell.

If you were making a product of artificial "Grow-Lites" for plants, what color light should
UNO [17]

Answer:

<u>-blue and red light</u>

Explanation:

Plants produce sugars or carbohydrates during the process of photosynthesis. They absorb light energy from the electromagnetic spectrum with pigments within the thylakoid membrane, like chlorophyll a, chlorophyll b.

Chlorophylls are made of ringed molecules chlorine, a hydrogenated form of porphyrin with a magnesium ion bonded to four atoms of nitrogen. Chlorophyll a shows the most absorption of red light  (642 nm) and blue light (372 nm); while chlorophyll b shows the most absorption at 626 nm and 392 nm.  

Different types of chlorophyll sidechains change the molecules' absorption ranges; A's methyl group is bound at carbon 7,  B's aldehyde (CHO) ring is bound at carbon 7.  Both absorb light from orange-red and violet-blue wavelengths. As such, the best light wavelengths for photosynthesis are within the blue and red wavelengths (425–450 nm) and (600–700 nm).
