specific for ocr gateway additonal science B.

what are the 4 minerals which plants need? -nitrates -phosphates -potassium compounds -magnesium compounds
what are nitrates used for? to make proteins for growth
what are phosphates used for? -in respiration (releasing energy) -growth, especially in roots
what are potassium compounds used for? in respiration and photosynthesis
what are magnesium compounds used for? in photosynthesis
what does mineral deficiency mean? when a plant doesn't have enough of a certain mineral
what are some symptoms of plants when there's no nitrates? -poor growth -yellow leaves
what are some symptoms of plants when there's no phosphates? -poor root growth -discoloured leaves

what are some symptoms of plants when there's no magnesium? yellow leaves
explanation of how nitrates are used nitrogen in nitrates used to make amino acids amino acids join together to make different proteins such as enzymes
explanation of how phosphates are used phosphorus in phosphates used to make cell membranes and DNA DNA carries genetic information
explanation of how potassium is used helps make some enzymes enzymes speed up chemical reactions such as photosynthesis and respiration
explanation of how magnesium is used makes chlorophyll molecules
what is active transport? when special carrier molecules take mineral ions across plant cell membranes
how do we know that energy is needed for active transport? because an increase in the uptake of minerals is matched with an increase in its respiration rate
what are the minerals absorbed against? a concentration gradient
what do plants abosorb in different amounts and types? minerals
