Minerals for healthy growth Flashcards
Why does active transport happen in root hair cells?
because there is a higher concentration of mineral ions in the root hair cells than there is in the surrounding soil.
Why do plants need mineral ions?
Plants need certain elements in order to make the compounds required for healthy growth, and they get these elements by absorbing mineral ions
What if plant’s don’t get enough mineral ion’s?
plants don’t get enough of a particular element then they may develop a mineral deficiency. This will lead to specific symptoms, depending on which element they are deficient in
Why do plants need magnesium ions?
Magnesium is required to produce chlorophyll
If plants don’t get enough magnesium, they can’t make enough chlorophyll and so their leaves will turn yellow. The growth of the plant may also be stunted as they won’t be able to photosynthesise to produce sugars.
Why do plants need nitrates?
Nitrates contain nitrogen which is required to make amino acids and hence proteins.
Proteins are needed for cell growth, so if a plant doesn’t get enough nitrates it won’t grow properly. This leads to stunted growth and yellow leaves.
