Why do plants need photosynthesis
Extraterrestrial photosynthetic plant-type life may look quite look different in color because they will have evolved their own pigments based on the colors of light reaching their surfaces. of NASA's Goddard Institute for Space Sciences has modelled the light reaching the surfaces of Earth-sized worlds orbiting their host stars at distances hospitable to Earth-type life, where liquid water could exist on a planetary surface, where depending on the star's brightness (and color) and the planet's atmosphere. Kiang found that "plants" on Earth-like planets orbiting stars somewhat brighter and bluer than the Sun might look yellow or orange, and even look bluish by reflecting a dangerous overabundance of more energetic blue light. On the other hand, plants on planets orbiting stars much fainter and redder than the Sun might look black. Hence, astrobiologists seeking signs of life on planets outside the Solar System may want to look for colors reflected by planetary vegetation that is colored differently than the green wavelengths found on Earth (NASA/GSFC ; Spitzer ; ; ;; and ).
Considering that not all light energy is used for photosynthesis we propose an alternative hypothesis. In a previous experiment the pigment xanthophylls absorbed significant amounts of blue light. In new research it is found that this pigment could be an important component in a process called energy dissipation rather than photosynthesis. In order to not overwhelm the plant with photosynthesis and respiration, this photon energy goes to other functions or formations of the plant. Further research on the function of xanthophylls will need to be conducted in order to understand the processes of plant function.

The simulations indicated that habitable planets in multi-star systems could host exotic forms of the more familiar plants found on Earth. As indicated in NASA studies announced in 2007, plants evolved under dim red dwarf suns or in more distance habitable orbits around a brighter star may appear black to Human eyes because they would probably need to absorbing more parts of the visible wavelength range to more effectively exploit as much of the available light as possible. Indeed, some in particularly dim environments may also evolve to use energy from infrared or ultraviolet radiation to power photosynthesis.
Animals that consume plants also make use of this energy, as do those that consume those that consume plants, and so on to the top of the food chain.
As important a job as making all of the world's food is, there's another vital function that photosynthesis performs: It generates the oxygen that oxygen-breathing animals need to survive.
Why Do Plants Need Light? | Ambius
Temperature, carbon dioxide concentration and light intensity are factors that can limit the rate of photosynthesis.Plants also need mineral ions, including nitrate and magnesium, for healthy growth.
Below are things that plants need for photosynthesis:
Carbon dioxide (A colorless, naturally occurring odorless gas found in the air we breathe. It has a scientific symbol CO2. CO2 is produced by burning carbon and organic compounds. It is also produced when plants and animals breathe out during respiration)
Light (Even though both natural and artificial light is OK for plants, natural sunlight is usually great for photosynthesis because they have other natural UV properties that help the plant)
Chlorophyll (This is the green pigment found in the leaves of plants)
Nutrients and minerals (Chemicals and organic compounds which the plant roots absorb from the soil)
