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?
In a particular plant species, 2n=12. For this organism, how many chromosomes, and how many DNA molecules will be present per cell for each of the following?
e) root meristem cell in telophase of mitosis (cytokinesis complete)
f) microspore mother cell (in anther) in prophase 1 of meiosis
g) microspore mother cell in metaphase II of meiosis
h) pollen grain ( after meiosis is and cytokinesis complete)

2) Plant B is in the diploid phase. What is another name for this plant?
3) If A is the haploid phase, in which phase would you find sepals? Write just the letter of the individual corresponding to the correct phase
4) If B is the haploid phase, in which phase would you find synergids? Write just the letter of the individual corresponding to the correct phase

Knowing what you do about the molecular mechanisms of floral development, which of the following might explain the development of single-sex flowers? a. Expression of B-type genes in the presumptive carpel whorl will generate staminate flowers. b. Loss of A-type genes in the presumptive petal whorl will allow C-type and B-type genes to produce stamens instead of petals in that whorl. c. Restricting B-type gene expression to the presumptive petal whorl will generate carpelate flowers. d. All of the choices are correct.arrow_forwardYou are studying a plant with tissue comprising both green and white sectors. You wish to decide whether this phenomenon is due (1) to a chloroplast mutation of the type considered in this chapter or (2) to a dominant nuclear mutation that inhibits chlorophyll production and is present only in certain tissue layers of the plant as a mosaic.
