Original Khojo Papers practice question — not from a past board paper.
Answer
Photoperiodism is the response of a plant to the relative lengths of day and night, which determines when many plants flower. Vernalisation is the promotion of flowering by a period of low temperature, which some plants require before they will flower.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
