Investigating the effect of nitrate on cress plants Aim In this investigation the effect of nitrate concentration on the growth of plants will be investigated. This will include the finding of the minimum concentration to have a positive effect on the growth. The plants that I am going to study are cress and the nitrate that I will be using will using will be sodium nitrate. Background information. Plants have five requirements for living: - Carbon dioxide, this is needed for photosynthesis. Oxygen, this is needed for respiration. Organic nutrients, a few plant cells make their own nutrients, such as glucose by photosynthesis. Inorganic ions and water, all plants need these to grow and they are taken up by the roots and up the stem and soluble from soil water.
