Other plants use this type of reproduction to reproduce through bulbs or tubers, or shoots and suckers that form along lateral roots. See the Plant Biology concepts for additional information. Q: What kind of reproduction is vegetative reproduction? Choices: - sexual - meiosis - mitosis - asexual A:
