BIOLOGY PRACTICE TEST 2023 -
2024 WITH CLARIFIED QUESTIONS AND WELL ELABORATED ANSWERS ALREADY GRADED A +. 1.A plant, such as an iris, that reproduces asexually E most of the time probably is found in a changing environment. produces offspring that move into new environ - ments. lacks the ability to make flowers. forms spores. has offspring that live in the same environment as the parents. 2.An oak tree is a A sporophyte. gametophyte. gamete. spore. zygote. 3.The sexual life cycle of plants is described as alter- D nation of generations because it alternates between male plants and female plants. reproduct ive plants and vegetative plants. eggs and sperm. sporophytes and gametophytes. flowers and spores. 4. The sporophyte produces d spores by mitosis. spores by meiosis. gametes by mitosis. gametes by meiosis. gametes by mitosis, followed by meiosi 5. Spor es and gametes are both haploid reproductive c cells. What is the difference between the two? Spores germinate and grow into a multicellular hap- loid gametophyte, and gametes fuse to form a diploid zygote. Spores fuse to form a diploid zygote that eventua lly becomes the sporophyte, gametes. Spores are found only in plants that reproduce asexually, and gametes are found only in plants that reproduce sexually. Gametes germinate and grow into a multicellular haploid gametophyte, and spores carry out fertiliza- tion. 6. In the alternation of generations, what is formed C when a spore germinates? A plant that produces spores when mature. An increased number of spores. A plant that meiotically produces sex cells. A haploid stage called the gametophyte. A haploid stage called the sporophyte. 7.results in the production of spores in B flowering plants. Fertilization Germination Meiosis Spermatogenesis Mitosis 8. In flowering plants, the sperm does not have to B swim to the egg. The sperm reaches the eggs by wind pollination. a pollen tube. burrowing through the embryo sac wall. cell division within the spore case. digestion of the seed coat. 9.A pollen grain is actually the A male gametophyte. female gametophyte. 10.Conifers do not have flowers to attract pollinators. A Instead, fertilization occurs via wind pollination.
