What plant pigments are involved in photosynthesis? - 2114467
Chloroplasts are the main cellular structure that is involved in plant photosynthesis
How are plant pigments involved in photosynthesis
Current understanding is that the earliest photosynthetic organisms were aquatic bacteria, some of which are still around today. One of these, halobacterium halobium, grows in extremely salty water. It makes use of the bacteriorhodopsin pigment. The chlorophyll system developed to use the available light, as if it developed in strata below the purple bacteria and had to use what it could get.
But what about the development of land plants? Why did they stay green? The thoughts are that they had plenty of light and were not pressured to develop more efficient light gathering. That is, the light was not the limiting resource in photosynthesis for plants.
The Leaf It's amazing what's inside a leaf
We have explored some of the many ways that sunlight sustains life on Earth, with a special emphasis on photosynthesis (e.g. ; ), and on how the interaction of light with pigment molecules underlies our experience of color (e.g. ; ). In this way, we have inquired beyond the immediate appreciation of the beauty of the plant world that is all around us, and into the processes through which light energy makes most of life on Earth, as well as our own visual experience, possible. We also looked at why the sky looks blue and the sunsets red, even though no pigments are involved except for those in our eyes.
There are many genes involved in the development of a red hosta from locator genes to the ablity to develop anthocyanins, but Bob is confident that some day breeders (if not himself) will develop a red hosta. He has seen a hosta with purple pigment in the leaf blade, not just along the veins. Unfortunately, you will not find this plant on the market, because on the first warm day the leaves curl up and turn brown. Not a great addition to any garden.
sunlight is absorbed by chlorophyll in a leaf B
· All of these various forms of chlorophyll, except chlorophyll a are considered as accessory pigments because they unlike chlorophyll a cannot convert photons of light into energy, they assist chlorophyll a in the energy absorption process and then passed their absorbed energy on to chlorophyll a for energy production. This makes chlorophyll a alpha dog in the process of photosynthesis because without chlorophyll a, plants could not actually across the light energy they absorb.
· In plants, algae and cyanobacteria, pigments are the means by which the energy of sunlight is captured for photosynthesis. However, since each pigments reacts with only a narrow range of the spectrum. There is usually a need to produce several kinds of pigments, each with a different colour to capture more of the sun's energy.
