C) lacks the ability to make flowers. D) forms spores. E) has offspring that live in the same environment as the parents. - correct answerE An oak tree is a A) sporophyte. B) gametophyte. C) gamete. D) spore. E) zygote. - correct answerA 8) The sexual life cycle of plants is described as alternation of generations because it alternates between A) male plants and female plants. B) reproductive plants and vegetative plants. C) eggs and sperm. D) sporophytes and gametophytes. E) flowers and spores. - correct answerD 9) The sporophyte produces A) spores by mitosis. B) spores by meiosis. C) gametes by mitosis. D) gametes by meiosis. E) gametes by mitosis, followed by meiosi - correct answerd 1) Spores and gametes are both haploid reproductive cells. What is the difference between the two? A) Spores germinate and grow into a multicellular haploid gametophyte, and gametes fuse to form a diploid zygote. B) Spores fuse to form a diploid zygote that eventually becomes the sporophyte, gametes. C) Spores are found only in plants that reproduce asexually, and gametes are found only in plants that reproduce sexually. D) Gametes germinate and grow into a multicellular haploid gametophyte, and spores carry out fertilization. - correct answerc 10) In the alternation of generations, what is formed when a spore germinates? A) A plant that produces spores when mature. B) An increased number of spores. C) A plant that meiotically produces sex cells. D) A haploid stage called the gametophyte.
