- The drooping, bell-like flower Aquilegia canadensis is adapted for cross-pollination. However, if the plant has not been pollinated previously, self-pollination can occur. However, if cross pollination occurs after self-pollination takes place, the pollen from cross pollination reaches the style before the pollen from self-pollination. Using course concepts and vocabulary 1) Provide a reasoning for this phenomenon. 2) Would this adaptation for reproduction be beneficial for the plant?arrow_forwardWhich of the following is an advantage of asexual reproduction? a. Cuttings taken from an adult plant show increased resistance to diseases. b. Grafted plants can more successfully endure drought. c. When cuttings or buds are taken from an adult plant or plant parts, the resulting plant will grow into an adult faster than a seedling. d. Asexual reproduction takes advantage of a more diverse gene pool.arrow_forwardno need to explain just need to know if its a,b,c or d 1.) The life cycles of some plants contains two alternating generations of adults. The diploid adult is called the sporophyte generation and the haploid adult is the gametophyte generation. The diploid plants of the sporophyte generations produce spores by the process of: a.) amitosis b.) meiosis c.) mitosis d.) binary fission 2.) A scientist was examining a human cell with 22 pairs of autosomes, an X chromosome and a Y chromosome. What conclusions can we drawn about the cell? a.) It is a somatic, diploid and male cell. b.) It is a somatic, diploid and female cell. c.) It is a gametic, haploid and male cell. d.) It is a gametic, diploid and male cell. 3.) What will be the number of chromosomes in Turner’s syndrome and Klinefelter's syndrome of an organism whose haploid number is 20? a.) 39 in Turner’s syndrome and 41 in Klinefelter’s syndrome b.) 41 in Turner’s syndrome and 39 in Klinefelter’s syndrome c.) 19 in Turner’s…arrow_forward

- Under which of the following conditions would pollen from an S2S5 plant successfully pollinate an S1S5 flower? a. Using pollen from a carpelate flower to fertilize a staminate flower would be successful. b. If the plants used gametophytic self-incompatibility, half of the pollen would be successful. c. If the plants used sporophytic self-incompatibility, half of the pollen would be successful. d. Pollen from an S2S5 plant can never pollinate an S1S5 flower.arrow_forwardIn plant life cycles, (a) the first products of meiosis are gametes (b) spores are part of the diploid sporophyte generation (c) the embryo gives rise to a zygote (d) the first stage in the diploid sporophyte generation is the zygote (e) the first stage in the haploid gametophyte generation is the prothallusarrow_forwardWhat is/are the Process/es of Coevolution in insects and plants?
