2020年10月10日 · I was wondering what alternatives to chlorophyll there were for if the peak stellar output of a star isn’t a green wavelength like on earth. I know that Retinal can be a good choice for purple plants and melanin is great for black plants, but what other options are there?

2023年12月5日 · In this article, we'll talk about four plants that lack chlorophyll. 1. Rafflesia. 2. Dodders. 3. Broomrapes. 4. Monotropes. A rafflesia infests a Tetrastigma. 1. Rafflesia is a genus of parasitic plants belonging to the family Rafflesiaceae. These plants lack any discernible stems, leaves, or roots.

2024年3月22日 · So, would I need an alternative chemical that converts light energy to chemical energy (like what chlorophyll does on earth)? If so, what would be some likely candidates for this purpose? Thanks in advance.

2011年12月31日 · Their chlorophyll-alternative chemical, rhodopsin, gives them (and the areas they inhabit) their pinkish-purple color. Bacterial rhodopsin: evidence for a new type of phototrophy in the sea. By absorbing the sun’s blue and red light, chlorophyll loses electrons, which become mobile forms of chemical energy that power plant growth.

2015年3月6日 · Are there any reasonably plausible alternatives to the process used by our plants on earth (Carbon Dioxide, Chlorophyll, Oxygen) around which an ecosystem could be built in a planet with a completely different atmosphere? Would every planet with life on it need to have a carbon+oxygen based life-cycle or are there any viable alternatives?

2023年6月11日 · What would be a viable chlorophyll like protein be for a cyanobacterium that absorbs infrared light at the 5-20 micron range to produce energy in the form of ATP?

Chlorella and chlorophyll are often confused due to their similar-sounding names and the similar health claims associated with both. Chlorella is a green algae that contains chlorophyll, a compound found in green plants that is crucial to the process of photosynthesis.

2023年6月1日 · Chlorophyll (green), carotenoids (orange, yellow), anthocyanins (red, blue, purple), and flavonoids are among these pigments (red, blue, purple). Natural pigments give animals and insects their hues as well. Carotenoids are found in the feathers, scales, and fur of many birds, fish, and reptiles.

Among the numerous alternatives to synthetic pigments, microorganisms, as one of the rich sources of active substances, are gradually being recognized for their environmentally friendly, low-cost, and high-yield advantages, with demand for their commercial use growing steadily.

2021年8月19日 · Retinal ( C20H28O ) is a good alternative to chlorophyll. There's a fungus called Cryptococcus neoformans which uses Melanin C 18 H 10 N 2 O 4 to feed on ionizing …
