      I don’t actually know exactly what is in plant foods, but it will be there to provide all the nutrients that a plant needs to live. Plants need to take in nutrients like sugars and proteins just the same as we and other animals need to do. These nutrients are taken in to the plant through roots (or just into the stalk with flowers in a vase) and then the nutrients can pass up through the tubes that are in the middle of the stalk. The nutrients can then be used for production of energy or for production of DNA or proteins, so that the cells of the plant can do all of the things to keep them alive.

      I hope this answers your question!

      Hi allama

      I had to Google this but apparently it contains organic matter, so things like carbon and oxygen, and 3 main minerals; nitrogen, phosphorus and potassium,with a little sulphur added. All these things are needed for the plant grow, and as Dave says they are taken up by the roots. Nitrogen will make the plant grow faster and produce more leaves, phosphorus makes the roots work better and potassium will give bigger flowers and prevent infection.

      I hope that answers your question!
