孤雌生殖:有的植物,卵细胞不经过受精就能发育形成胚,从而形成有胚的种子。parthenogenesis: A type of asexual reproduction in which a female gamete(配子) or egg cell develops into an individual without fertilization, especially as a normal process in some invertebrates(无脊椎动物) and lower plants. The term comes from the Greek words parthenos (meaning virgin) and genesis (meaning creation.)
