Standard 5-Biodiversity and Change
CLE 3210.5.1 Associate structural, functional, and behavioral adaptations with the ability of organisms
to survive under various environmental conditions.
- SPI 3210.5.1 Compare and contrast the structural, functional, and behavioral adaptations of
animals or plants found in different environments.
1. For each plant adaptation described identify it as a plant from one of the following biomes and
explain why: desert, temperate deciduous forest, taiga (coniferous forest)
a. Spines to discourage animals from eating the plant:_________________________________
b. Most trees drop their leaves in the cold winter:____________________________________
c. Some plants called succulents store water in their stems or
leaves:_______________________________
d. Many trees are evergreens so they can photosynthesize as soon as
possible:________________________________
e. Wildflowers grow on forest floor in early spring before leaves block the
sunlight:________________________________
f. Many trees produce needle-shaped leaves which prevent excessive water loss an shed
snow easier:_________________________________
2. For each animal adaptation described identify it as an adaptation that an animal would have in
one of the following biomes and explain why: desert, temperate deciduous forest, taiga
(coniferous forest)
a. Animals commonly burrow during the day to escape the
heat:_________________________________
b. Some animals migrate to and from to avoid extreme cold during
winter:__________________________________
c. Some animals hibernate to avoid cold temperatures of
winter:__________________________________
d. Long broad ears and short hair to shed heat more
efficiently:________________________________
e. Two distinct mating seasons in the fall and spring depending on the
animal:_________________________________

CLE 3210.5.2 Analyze the relationship between form and function in living things
- SPI 3210.5.2 Recognize the relationship between form and function in living things.
3. Explain how the form (shape/design) of an animal or plant complements its function. Give a
few examples (at least one from plants and one from animals).
4. The following picture is of 4 different finches from the Galapagos Islands. They are an example
of the type of finches that Darwin may have observed. Explain the most obvious difference
between the 4 and describe what environmental change or condition could cause these
differences.

CLE 3210.5.3 Explain how genetic variation in a population and changing environmental conditions
are associated with adaptation and the emergence of new species.
- SPI 3210.5.3 Recognize the relationships among environmental change, genetic variation,
natural selection, and the emergence of a new species.
5. Describe genetic drift (bottleneck effect).
6. Describe gene flow.
7. Describe how mutation and non-random mating contribute to genetic variation in a
population.
8. List and describe the four different types of natural selection that we described in our notes.
9. List the two types of speciation we discussed, describe them, and describe a scenario for each.
(include an explanation of geographic isolation).

10. Differentiate between divergent and convergent evolution.
CLE 3210.5.4 Summarize the supporting evidence for the theory of evolution.
- SPI 3210.5.4 Describe the relationship between the amount of biodiversity and the ability of
a population to adapt to changing environment.
11. How does the fossil record support the theory for evolution?
12. What are homologous structures and how do they provide support for the theory of evolution?
13. What are vestigial structures and how do they provide support for the theory of evolution?
14. What is fitness? Describe the benefit of mimicry to the fitness of an organism?

CLE 3210.5.5 Explain how evolution contributes to the amount of biodiversity.
- SPI 3210.5.5 Apply evidence from the fossil record, comparative anatomy, amino acid
sequences, and DNA structure that support modern classification systems.
CLE 3210.5.6 Explore the evolutionary basis of modern classification systems.
- SPI 3210.5.6 Infer relatedness among different organisms using modern classification
systems.
15. Organize the following organisms according to the questions below and then draw a
cladogram.
ORGANISMS: turtle, frog, ant, human, dog, octopus
- First, separate the organisms into two groups: vertebrates and invertebrates
- Second, take your invertebrates and identify which have an exoskeleton and which do not
- Third, take your vertebrates and separate them based on the presence of an amniotic egg
(include live birth organisms in this group)
- Fourth, take the organisms with amniotic eggs and separate based on presence of hair
- Fifth, take the organisms with hair and separate based on bi-pedal locomotion (walks on two
legs).

17. Identify the 3 domains and 6 kingdoms we discussed in class and identify some important
characteristics of each kingdom.
Checks for Understanding:
5.1- Create a graphic organizers to demonstrate the relationship between form and function in
representative organisms.
5.2- Explain how natural selection operates in the development of a new species.
5.3- Associate fossil data with biological and geological changes in the environment.
5.4- Analyze a variety of models, samples, or diagrams to demonstrate the genetic relatedness of
organisms.
5.5- Use a dichotomous key to identify an unknown organism.
