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?
Explain when in nature seedlings are exposed to dark vs. light environments and connect this to an adaptive evolutionary explanation for why seedlings respond in different ways to dark vs. light environments in regards to pigmentation. (3 pts)
