Flashcards in B4f- Plants need minerals Deck (12)
What minerals do fertilisers contain?
Why do plants need nitrates?
to make amino acids for proteins which are needed for cell growth
Why do plants need phosphates?
to make DNA and cell membranes for respiration and growth
Why do plants need potassium?
to help enzymes in photosynthesis and respiration
Why do plants need magnesium?
to make chlorophyll for photosynthesis
What do plants lacking in nitrates look like?
What do plants lacking in phosphates look like?
poor root growth
What do plants lacking in potassium look like?
poor flower and fruit growth
What do plants lacking in magnesium look like?
How do root hairs take in minerals using active transport?
Active transport uses energy from respiration to help the plant pull minerals into the root hair using the concentration gradient
What is the concentration gradient?
a low concentration to a high concentration (eg minerals in the soil to the minerals in the root hair cell)
