Biology lesson: Plants are made up of water, proteins, fats, DNA, RNA, carbohydrates and chlorophyll.

Plants get hydrogen and oxygen from water in the soil, and carbon and oxygen from carbon dioxide and oxygen in the atmosphere. Water and carbon dioxide are used to synthesise food during photosynthesis. Oxygen is used to release energy from food during respiration. In addition to these three elements, plants need a number of minerals for healthy growth. These are absorbed through the roots as mineral ions dissolved in the soil water. Two important mineral ions needed by plants are: nitrate - for making amino acids, which are needed to make proteins and magnesium - for making chlorophyll
