What are three functions needed for a plant to survive

Water, Sun/Heat, and Carbon Dioxicide/Air

Sorry About Spelling!

Well one is to water it in order to keep the nutrients heathy in the roots two is to move it in sun, half sun, or no sun (depending on the plant) it requires sun for food but the no suns make their own and three make sure it has rich soil its best to have rich soil in order for the roots to move more in the dirt
