Question
Chapter 7.2, Problem 1HYEW
Summary Introduction
To determine:
The color of plants on other planets
Introduction:
Biologist Nancy Kiang developed a hypothesis suggesting the colors of alien plants. The most abundant type of star called M-type star in the galaxy emits redder and dimmer light as compared to the sun. If plants evolve on an alien planet which revolves around M-star, the photosynthetic pigment would absorb all the light of visible spectrum reflecting no light.

Students have asked these similar questions
Consider plants that live in a forest's top, middle, or ground layer, as well as algae that live near the ocean's surface or in deep water. Would you expect the same photosynthetic pigments to be present in these different environments in the same species? Why do you think that is the case? What method would you use to test your hypothesis?
What will likely happen to your plant if it will be placed in a dark area with no light?
A.The plant will not be able to absorb sunlight
B.No chlorophyll will be formed and the leaves will become whitish or pale yellow
C.Plants will evolve to adapt in an environment with no light
D.BothA and B
E. BothA and C
. Plants can harvest the energy from light, but also rely on light as a stimulus to control other processes. Briefly describe one example of how plants use light for something other than photosynthesis, including the processes, structures and/or molecules involved.

- Duckweed is a tiny floating aquatic plant that can reproduce so rapidly that it can completely cover the surface of small fish hatchery ponds. One proposal to limit the growth of this invasive plant is to use colored panels to shield the ponds, inhibit photosynthesis, and kill this pest. What color filters would you order for the panels in this project? What wavelengths of light will be absorbed by these filters? Do you think this proposal will be effective in killing the duckweed?arrow_forwardPlants that grow in the understory of the tropical rainforest under a heavy canopy of tall trees have developed adaptations to the dark, hot, and moist environment. Knowing that darker green leaves are richer in chlorophyll than lighter green leaves, which of the following characteristics would you expect to find in their leaves? A. small dark green leaves with few stomata B. small pale green leaves with few stomata C. large dark green leaves with many stomata D. large pale green leaves with many stomataarrow_forwardAs energy passes from blue-absorbing chlorophylls down to red-absorbing chlorophylls, surprisingly, no energy passes from lower energy-absorbing pigments back to higher ones (in other words, the process is irreversible). Why might that be?arrow_forward

Chlorophyll is the main plant pigment molecule in plants. b. Chlorophyll absorbs light energy from the sun. c. Carotenoids are mainly responsible for the fall color in leaves that we see. d.

- Photosynthesis sustains plant growth, and inputs of sunlight sustain photosynthesis. Why, then, do seedlings that germinate in a fully darkened room grow taller than seedlings of the same species that germinate in full sun?arrow_forwardWhat is the eighth concept used for studying plants? It is difficult to avoid using the phrase “in order to” when referring to plants. Change the following sentences to be more accurate. The first one is done as an example:a. Plants have leaves in order to photosynthesize. “Plants have leaves that photosynthesize,” or “photosynthesis in plants occurs in leaves.”b. Plants have flowers in order to reproduce.c. Plant cells divide in order to make more cells.d. Wind-pollinated plants have their flowers located high above the ground in order to be exposed to stronger wind.e. Some plants have red flowers to attract hummingbirds.f.

- Mention any three adaptations found in plants to favor the process of photosynthesis.arrow_forwardA botanist has been examining three plants, measuring the amount of acid in their cells, and examining sections of their leaves under the microscope. Numbers in the table are in relative units. Part A: Identify the kind of photosynthesis being done by each plant. Explain how enzymes contribute to this data. Part B: Decipher the origin of each plant if one is from the Mojave Desert, one is from a sand dune in Florida, and one is from Minnesota, and explain how you deciphered this.arrow_forwardThree of the same species of plant are each grown under a different colored light for the same amount of time. Plant A is grown under blue light, Plant B is grown under green light, and Plant C is grown under orange light.
