Plant transport

Traps in Plant transport

• Mixes up a pair of similar technical terms
  Make a two-column table for each confusable pair with one defining feature each, and a memory hook (aTLas holds the 'world' (skull) and nods; aXis lets you shake 'no'). Underline the defining feature the stem gives before you look at the options.
• Plant transport misconceptions
  Xylem: water and mineral salts upwards (dead, lignified vessels). Phloem: manufactured food (sucrose) both ways (translocation). Transpiration rises with heat, wind, low humidity and light; falls in humid, still air.
• Takes one contributing factor as the whole answer
  Watch for 'only', 'just', 'mainly'. Ask: is this the MAIN reason, or one contributor? If it would need other things to work (plasma proteins need platelets), it is incomplete.
• Respiration misconceptions
  Respiration is a chemical process in cells releasing energy from food. Aerobic: glucose + O₂ → CO₂ + H₂O (+ much ATP). Anaerobic in muscle: lactic acid; in yeast: ethanol + CO₂ (little ATP). Breathing is the mechanical ventilation.
• Gives the job of a neighbouring structure or stage
  Learn structures as pairs of 'name → one job' and contrast neighbours: ribosome makes protein, mitochondrion releases energy; cochlea hears, semicircular canals balance. When two options sit in the same organ or process, ask which one does exactly the job in the stem.
