plants need minerals Flashcards
what do plants need nitrates for?
to make proteins needed for cell growth
what do plants need phosphates for?
involved in respiration and growth
what do plants need potassium compounds for?
involved in respiration and photosynthesis
what do plants need magnesium compounds for?
involved in photosynthesis
what is nitrogen used to produce?
amino acids to help enzyme action in photosynthesis and membranes
what is potassium used to help?
enzyme action in photosynthesis and respiration
what is magnesium used to make?
chlorophyll which is essential for photosynthesis
what does a lack of nitrate cause?
poor growth and yellow leaves
what does a lack of phosphate cause?
poor root growth and discoloured leaves
what does a lack of potassium cause?
poor flower and root growth and discoloured leaves
what does a lack of magnesium cause?
yellow leaves
where are minerals usually present?
in soil in low concentration
how are minerals take up by a plant?
by root hair cells by active transport, rather than by diffusion or osmosis. A system of carries transport selected minerals across the cell membrance
what does active transport allow?
minerals to enter root hairs already containing higher amounts of minerals
what does the uptake of minerals against a concentration gradient require?
energy from respiration
