How would the process of photosynthesis be affected if a plant did not have chlorophyll?

Answer 1

less glucose would be available for energy production.

Answer 2

Chloroplasts are highly specialized plastid organelles that house the photosynthetic pigment reactions in plants. These functions are found in less specialized plastids of algae. Further back in complexity we find the basal pigment absorbing light reactions in bacteria are able proceed without internal organelles so plants would still be like cyanobacteria or other autotrophic bacteria types that lack organelles. There would be photoautotroph plants like purple sulfur Halobacteria, and the cyanobacteria but without organelles housing the chlorophyll or other pigment based light reactions. It is likely the terrestrial plants could exist with another method of isolating the light reactions. Plants as terrestrial photoautorophs could have come up from a lineage of photosynthetic bacteria with mitochondria to make them eukaryotic but not chloroplasts.
The plants would possibly retain the photosynthetic reactions as a part of the cellular membrane in a highly folded structure but one made solely from the parental lipid membrane like bacteria do it. The membrane would not be double. The plants would carry all the genetic information for the entire photosynthetic process in the nucleus. There would be an elaborate genetic regulatory sequence of proteins so the cells could adjust the level of photosynthesis since they could not just have more chloroplast organelles per cell. Instead they would have greater folding and regionalization of very specialized cells for photosynthesis.
It happened that a cell population acquired the entire photoautotrophic endosymbiont so could out compete any lineage evolving the regulatory elaborations to isolate the light chemistry so this is the plastid pathway that survived to become the terrestrial plants but it is not the only pathway that could function.

Answer 3

If the chloroplast did not absorb water[H2O], the plant will not create ATP and carrier molecule with hydrogen. If ATP did not exist, we will not have oxygen[O2 ]. All mammals will die.

Answer 4

photosynthisis would no longer be possible because chlorophyll is the the green color produced through photosynthisis

Answer 5

The chlorophyll molecules would have fewer electorns to replace the ones lost.
