Question

Why do flowering plants need substances such as water, mineral nutrients, organic nutrients and hormones? Do non flowering plants need the same substances?

Answer 1

Water,minerals nutrients, organic nutrients all do the same work which they do in our body.that is mainly growth.water also used in photosynthesis or like processes.
These are essential substances for a plant.in the absent of these the plant will not grow/survive.
Hormones help in controlling various process like growth,flowering,fruit ripening,..etc.
In the absence of hormones the various process related to plant will not work well.
The plant cannot survive in the absence of these things.which are vital(most important) substances for a plant.
