Reproduction — IGCSE Biology (0970) questions by topic
Reproduction questions test structural and terminological precision: naming the reproductive organ responsible for releasing eggs, recognising the correct term for unspecialised cells, distinguishing asexual from sexual offspring outcomes, and matching processes such as menstruation and ovulation to their correct descriptions.
Choose, identify, state, describe and complete carry 1 to 17 marks across 53 real questions from 2023 to 2025 papers. Because menstruation and ovulation are so easily swapped in a rushed answer, working through each question and checking the instantly marked result catches that specific confusion before it affects a whole set of related terms.
