Sexual Reproduction POLLINATION / FERTILIZATION – Requires two parent plants (ex. Flowering plants that make seeds). Asexual Reproduction Involving only one parent plant – PRODUCES OFFSPRING IDENTICAL TO THE PARENT ! If a plant is cut or damaged, it can sprout new growth from the stems, roots, or leaves (NOT SEEDS). What is sexual reproduction in plants? What is asexual reproduction in plants?
