Some Questions For Thought And Study:
- Compare and contrast autotrophs and heterotrophs.
- Discuss the consequences of being autotrophic. How have plants responded to life as
- Briefly summarize the five major consequences of sedentary, autotrophic life. How have
plants responded to each?
- What is a positioning mechanism? Provide some examples.
- How do plants exploit their environment? Consider dendritic form, asexual reproduction,
indeterminate growth, heterophylly, foraging and architectural design in your response.
- Compare and contrast animals and plants in terms of body design (i.e. architectural vs.
- Discuss some of the mechanisms by which plants sense changes in the environment. Why are
- Identify some of the physical and biological threats to plants. How do plants protect
themselves from these dangers?
- How do plants find a "mate" and disperse offspring?
- Discuss some of the problems unique to the plant way of life. In general how have plants
responded to each of these problems?
- Think about the statement "Plants are smarter than you think!"
- Identify the characteristics of the plant kingdom.
- Autotrophs are typically non-motile and heterotrophs are typically motile. Why did
evolution favor this situation?
- Explain why leaves are broad and flat.
- Compare animals and plants in terms of nutrients (type, concentration, location).
- Explain why plants are not limited by size.
- From a botanical perspective, some corals can be considered heterotrophic plants.
- Explain why coral is only found in relatively shallow, clear water.
- Identify the specialized structures (and their function) that plants use for
- Is a carnivorous plant autotrophic?
- Describe some pollination vectors/mechanisms.
- Describe some fruit dispersal systems.
- Explain why plants are dendritic, but animals are not.
- In what way is a tree like a coral colony?
- In what regard do plants forage for food? Identify some foraging strategies.
