To review:
The dependency of expected floral colors of the two species of Mimulus on their respective pollinators.
Given:
In the given study, two species of the monkeyflower Mimulus cardinalis and M. lewisii were compared on the basis of their pollinators. Figure 1 given below shows the two species of monkeyflower (Mimulus).
Figure 1: The two species of monkeyflower (Mimulus).
Introduction:
Pollination plays an important role in the life cycle of a plant. It helps in fertilization of the male gametes (pollens) with the female gametes (ovules). Pollination is carried out with the help of different agents like insects, birds, and animals. Every organism visiting flower does not cause pollination.
Explanation of Solution
The two flowers being closely related need not to have same morphology. The morphology of flowers is decided by their genetic trait. Apart from the genes, the type of pollinators leads to the adaptation and
M. cardinalis is pollinated by hummingbirds while M. lewisii pollinated by bees and other insects (as shown in Figure 2 below). They are also isolated from each other through geographical distribution, which has led to the difference in colors of petals.

Hence, the pollinators play an important role in the morphology of flowers, which also lead to the difference in the colors of closely related species.

- Look at the flower, observe color, size of petals and height of stamen and pistil. What type of pollination does it present? - Self pollination - wind cross pollination - bird cross politicizationarrow_forwardWhich statement about wind-pollinated plants is correct? Their stamens and stigmas are inside the flower and, compared to insect-pollinated plants, they have large petals Their stamens and stigmas are outside the flower and, compared to insect-pollinated plants, they have small petals Their stamens and stigmas are outside the flower and, compared to insect-pollinated plants, they have large petalsarrow_forwardIn the experiment conducted to test why individuals in the tree species Fuschsia excorticata retain flowers after they turn red even though the trees pollinate and offer a nectar reward only when flowers are green (Figure attached 10.28 first tested the 'pollinator-attraction' hypothesis that red flowers attract pollinators: once drawn to a tree, pollinators could forage on the green flowers still present, increasing overall pollination efficiency. Please assess the lowercase-Roman-numeral-labelled statements that appear immediately below and click the uppercase-letter-labelled response that appears below and conveys the most accurate information. i. If the pollinator-attraction hypothesis were correct, then green flowers surrounded by red flowers should receive more pollen than should green flowers surrounded by only green flowers. ii. The prediction in statement i could be tested by removing red flowers from some trees, forming one experimental group, and leaving red flowers on…arrow_forward
