Unit 7 – Diversity Part II– Plant
Diversity: an evolutionary perspective
|
|
Essential
Questions:
- What qualities and
characteristics does an organism have to classify as a plant?
- Where did plants come from?
- What difficulties do plants have
to face in order to live on land?
- What adaptations have plants
evolved to thrive on land?
- What are the major groups of
plants?
- How are the major groups of
plants differentiated from each other?
- How are the major groups of
plants related to one another?
- By what process have plants
differentiated into these different groups?
- What are bryophytes?
- In what ways are bryophytes
limited?
- What is the origin of vascular
tissue in plants?
- How does having vascular tissue
allow plants to thrive and become more advanced?
- What are seedless vascular
plants?
- How did seed plants evolve?
- What is the significance of the
seed and pollen?
- How have these adaptations
allowed seed plants to diversify?
- What are gymnosperms?
- What are angiosperms?
- What is the purpose and function
of cones and flowers?
- What is the significance of
fruit?
- How have man and plants impacted
each other?

Objectives:
- Describe the characteristics that
would qualify an organism as a plant.
- Discuss the origins of plants
from an evolutionary perspective.
- Explore the impediments and
difficulties face by plants as they adapt to life on land.
- Discuss the adaptations plants
have made to life on land.
- Discuss alternation of
generations in plants.
- Construct a phylenogenetic tree
for the plant kingdom through dichotomy.
- Describe the characteristics of
bryophytes, identifying examples, investigating the typical reproductive
cycles (focus on alternation of generation), and the limitations of
bryophytes as terrestrial organisms.
- Define vascular tissue in plants
and discuss its significance.
- Explore the evolution of
vascular tissue in plants.
- Describe other terrestrial
adaptations that evolved along with vascular tissue.
- Identify and describe the major
groups of vascular seedless plants.
- Illustrate the life cycle of
seedless vascular plants using the fern as the example.
- Explore the development of seed
plants from an evolutionary perspective.
- Explain the significance of and
the evolutionary advantage of seeds.
- Explain the significance of
pollen from reproductive standpoint and from evolutionary adaptation
standpoint.
- Describe and identify examples
of the two major groupings of seed plants – Gymnosperms and angiosperms.
- Illustrate the typical
gymnosperm life cycle using the Pine tree as the example.
- Discuss the significance of the
flower.
- Identify the parts of the flower
and describe their role in angiosperm reproduction.
- Illustrate the reproductive cycle
of a generic angiosperm.
- Discuss the co-evolution between
angiosperms and animals.
- Compare and contrast the
different major groups of plants (adaptations to life on land,
reproductive cycles, diversity, etc.)
- Review the relationship in the
classification schemes for the plant kingdom.
- Discuss the role and impact of
plants in the overall environment.
- Discuss the interaction of man
and plants through agriculture.
- Discuss the interaction of man
and plants as a result of deforestation and the resultant impact on
carbon dioxide and oxygen levels, and greenhouse gasses and global
warming.
