we will die
and only microbes will survive
no,photosynthesis do not happen in all plants because all plants do not have cholophyll . plants that are green have cholophyll. so
If there were no green plants there would be no nitrogen cycle.If there were no green plants, the nitrogen that most organisms need wouldn't be transferred to all living things. Nitrogen is in green plants first, and then the herbivores, omnivores, and carnivores get it by eating the plants or eating the animals that eat those plants. Without green plants, those animals wouldn't really have anything to get the nitrogen from. Nitrogen is crucial to all plants in making amino acids and proteins which they need to survive, so there would be no life on Earth.
Almost all plants use photosynthesis, even some without chlorophyll. But green plants would not be green if they were not using chlorophyll-based photosynthesis.
there would be no water for the plants
Eventualy they will starve to death as all our energy comes from foods produced by plants.
Although it is a hypothetical situation. If all the green plants will disappear from earth then it will cause a decrease in the concentration of the oxygen to such a low level that it would not be sufficient for all the living organisms for breathing. Thus, it will result in their death.
they would all look the same
No not all plants are green
Green plants are the majority of plants everywhere and the basis of all food pyramids. Not only would all carnivores go extinct but all omnivores and herbivores as well. The atmosphere would become de-oxygenated and brown, gold, and red algae would explode in population. In their ecosystem, green plants require:mates
if the plants could walk they will go to a place where all that they need is there
Plants would grow gracefully and they might takeover the wild.
If plants disappeared from earth, all life on earth depending on photosynthesis would disappear.
