The 3 things are: sunlight, water, and oxygen
The three things that plants need for photonynthesis to occur is sunlight,carbon dioxide and water.
the 3 things plants need are not only needed for photosynthesis but for survival. these 3 necessities consist of, WATER, SUNLIGHT.SOIL.
the three essential ingredients that plants need to complete photosynthesis are carbon, nitrogen & sunlight.
THE THREE ESENTIAL THINGS NEEDED BY PLANTS FOR PHOTOSYNTHESIS ARE SUNLIGHT, CHLOROPHYLL AND CARBON DIOXIDE. IF ONE OF THE THREE FACTORS IS ABSENT PHOTOSYNTHESIS CANNOT TAKE PLACE(it is also known as black mans principle).
Well is that plants need to have food to get photosynesis too work.Two they need alot of sunlight.So in order for photosynthesis to work there a couple of things a plant will neeed if there going to stay alive.
they need light oxygen and water to live they make it by having those things
Water, (sun)light and carbon dioxide are three things that plants need to carry out photosynthesis. The water is used to replenish the lost electrons of chlorophyll and provide protons for the chemical gradient. The light is used as the source of energy to initiate photosynthesis. The carbon dioxide is the source of carbon to help make the complex sugar (made in the Calvin cycle).
They need Oxygen, water, and Sunlight.
sunlight, co2 and water, all plants need these things to produce glucose which is the main fuel source for plants ;)
Plants need sunlight to conduct photosynthesis.
The gas that plants need for photosynthesis is carbon dioxcide it is the only gas they take in.
They need light, Co2, water, and nutrients. It is photosynthesis.
