Plants Minerals Flashcards
Why do plants need nitrates ?
> A plant uses nitrates to make proteins
> Proteins are needed for cell growth
Why do plants need phosphates ?
> A plant uses phosphates in respiration (releasing energy)
> phosphates are also needed for growth, especially in roots.
Why do plant need
potassium compounds ?
> A plants use these in respiration and in photosynthesis
Why do plants need magnesium compounds ?
> A plant needs these in photosynthesis
What happens to nitrates when being used?
> Nitrogen in the nitrogen in the nitrates is used to make amino acids
> Amino acids are joined together to make different proteins such as enzymes
What happens to phosphates when used?
> Phosphorus in phosphates is used to make cells membranes and DNA
> DNA is carries genetic information
What happens to potassium compounds when used?
> Potassium is used to help make some enzymes. Enzymes speed up chemical reactions.
> Enzymes are needed in photosynthesis and respiration
What happens when magnesium compounds are used?
> magnesium is used to make chlorophyll molecules.
