Chapter 8, Problem 16TYK
Summary Introduction
To review:
Natural selection will favor C3 (Calvin cycle) plants or C4 plants if global warming raises the temperature. The effect of global warming on the geographical distribution of plants is to be mentioned.
Introduction:
Global warming is the process of heating up of the earth’s crust that causes long-term rise in the average temperature of earth climate. It causes the greenhouse effect where the emission of infrared radiations warms up earth’s atmosphere.

Read the scenario.
A botanist (a biologist who specializes in plant biology) is researching the enormous biodiversity of plants found in the tropical rainforest. As she hikes through the forest, she finds a section of forest that contains several types of flowering plants that are unidentified, meaning they have yet to be named and classified into a scientific group. She observes several different examples of this plant over several acres of forest and notes that the leaves and stems of these plants look very similar. The only part of the plant that varies is the flower. She notes that on the southern side of the forest, the flowers are bright pink and have 18 petals per flower. On the northern side of the forest, the flowers are white and have nine petals per flower.
The botanist wants to determine if the plants she has discovered are of the same species or different species. How would she be able to determine this?
a
If they are two different species, she could grow them…
The evolution of land plants was challanged by both exposure to direct sunlight as well as adjusting to gravity.
true or false?
How may the following trends in plant evolution be adaptive to living on land? (a) dependence on water for fertilization ➝ no need for water as a transport medium (b) homospory ➝ heterospory

Tropical rain forests have a greater diversity of vines than in any other environment on Earth, and most of these vines are woody. Develop a hypothesis to explain why natural selection has favored the evolution of more species of woody vines (as opposed to herbaceous vines) in tropical rain forests.arrow_forwardWhich of the following is not a characteristic of plants?
