Question

Why are minerals essential in photosynthesis?

Answer 1

Just as people need calcium in their diets for strong teeth and bones, plants need the mineral to build sturdy cell walls and healthy root systems. Calcium also helps transport other nutrients from the roots to the leaves and flowers.

Two important mineral ions needed by plants are nitrate - for making amino acids, which are needed to make proteins. Water and carbon dioxide are used to synthesise food during photosynthesis. ... These are absorbed through the roots as mineral ions dissolved in the soil water.
