You want beans in a jar to germinate. Which set of conditions must you provide?

1. Water softens the testa and acts as the solvent in which the seed's enzymes work. 2. An optimum temperature is needed because those enzyme reactions are temperature-sensitive. 3. Oxygen is needed for respiration, which supplies energy for cell division and for moving food to the growing regions. 4. Soil is not required at all — a seed germinates perfectly well in a jar of damp cotton wool. 5. Carbon dioxide is produced by that respiration rather than needed for it, and stored food affects viability rather than being an external condition. _Source: NECTA CSEE 2021 Biology 033, Question 1: Multiple Choice, item (vii)_
