Respiration is described as a universal process.
State what is meant by 'universal' in this description.
A student says:
'Plants photosynthesise during the day, so they only respire at night.'
Explain why the student is wrong.
Root hair cells take in mineral ions from the soil by active transport. Active transport uses energy from ATP.
A scientist adds a chemical to the soil that stops respiration in root cells.
Predict and explain the effect on the uptake of mineral ions by the root hair cells.
