  • Select two of the following three pairs and discuss the evolutionary relationships between the two members of each pair you have chosen. In your discussion include 3 structural adaptations and their functional significance.

    • PAIR A: green algae & vascular plants

    • PAIR B: prokaryotes & eukaryotes

    • PAIR C: amphibians & reptiles

Essay Dissection

Select two of the following three pairs and discuss the evolutionary relationships between the two members of each pair you have chosen. In your discussion include 3 structural adaptationsand their functional significance.

PAIR A: green algae & vascular plants

PAIR B: prokaryotes & eukaryotes

PAIR C: amphibians & reptiles


Essay 2 1995 1 l.jpg
Essay 2: 1995#1

  • Angiosperms (flowering plants) and vertebrates obtain nutrients from their environment in different ways.

    • A. Discuss the type of nutrition and the nutritional requirements of angiosperms and vertebrates.

    • B. Describe 2 structural adaptations in angiosperms for obtaining nutrients from the environment. Relate structure to function.

    • C. Interdependence in nature is evident in symbiosis. Explain two symbiotic relationships that aid in nutrient uptake, using examples from angiosperms and/or vertebrates. (Both examples may be angiosperms, both may be vertebrates, or one may be from each group.)


Essay 3 1998 3 l.jpg
Essay 3: 1998#3

  • The evolutionary success of organisms depends on reproduction. Some groups of organisms reproduce asexually, while others reproduce both sexually and asexually.

    • Using THREE different organisms, give an example of one organism that reproduces sexually, one that reproduces asexually, and one that reproduces BOTH sexually and asexually. For each organism given as an example, describe two reproductive adaptations. These adaptations may be behavioral, structural, and/or functional.

    • What environmental conditions would favor sexual reproduction? Explain. What environmental conditions would favor asexual reproduction? Explain.


Essay 4 1996 3 experimental l.jpg
Essay 4: 1996 #3 (Experimental)

  • Numerous environmental variables influence plant growth. Three students each planted a seedling of the same genetic variety in the same type of container with equal amounts of soil from the same source. Their goal was to maximize their seedling’s growth by manipulating environmental conditions. Their data are shown below.

    • Plant seedling mass (grams)

      Day 1 Day 30

      Student A 4 24

      Student B 5 35

      Student C 4 64

  • Identify THREE different environmental variables that could account for differences in the mass of the seedlings at day 30. Then choose ONE of these variables and design an experiment to test the hypothesis that your variable affects growth of these seedlings.

  • Discuss the results you would expect if your hypothesis is correct. Then provide a physiological explanation for the effect of your variable on plant growth.

    Essay 5 2005 3 l.jpg
    Essay 5: 2005#3

    • Angiosperms (flowering plants) have wide distribution in the biosphere and the largest number of species in the plant kingdom.

      • a. Discuss the function of FOUR structures for reproduction found in angiosperms and theadaptive (evolutionary) significance of each.

      • b. Mosses (bryophytes) have not achieved the widespread terrestrial success of angiosperms. Discuss how the anatomy and reproductive strategies of mosses limit their distribution.

      • c. Explain alternation of generations in either angiosperms or mosses.


    Essay 6 2003b 3 l.jpg
    Essay 6: 2003B #3

    Hormones play important roles in regulating the lives of many living organisms.

    a. For TWO of the following physiological responses, explain how hormones cause theresponse in plants.

    •  increase in height

    •  adjustment to change in light

    •  adjustment to lack of water.

      b. For TWO of the following physiological responses, explain how hormones cause the response in animals.

    •  increase in height

    •  adjustment to change in light

    •  adjustment to lack of water

      c. Describe TWO different mechanisms by which hormones cause their effects at the cellular level.


    Essay 7 2003 3 l.jpg
    Essay 7: 2003,#3

    • Regulatory (control) mechanisms in organisms are necessary for survival.

    • Choose THREE of the following examples and explain how each is regulated.

      •  Flowering in plants

      •  Water balance in plants

      •  Water balance in terrestrial vertebrates

      •  Body temperature in terrestrial vertebrates
