alleryDuring germination seeds respire actively. The dry matter of the seedling at first
ADecreases as stored food is oxidised
BIncreases because of new tissue addition
CStays constant under steady humidity
DDoubles due to water uptake from soil
Answer & Solution
Correct answer: A. Decreases as stored food is oxidised
1. Germinating seeds use their stored food for energy.
2. The food is oxidised to CO2 and water, which escape.
3. Until the seedling can photosynthesise, dry mass falls.
4. So option A is correct.
