Private Lives of Plants #2: Putting Down Roots
- The seeds of tropical vines like Monstera
germinate on the forest floor but need to find a support to grow into the
canopy to gather light. How do the seedlings locate a support? Why is this
plant �behavior� unusual?
- The shape of the leaves of some vines changes as the
plant creeps up a support. Describe the changes that occur and why.
- How is the red underside of the leaves of begonia and
other species advantageous to its survival?
- What are root hairs and what is their function?
- Tall trees, such as 300 foot redwoods, must move water a
long distance. Briefly describe how they accomplish this feat.
- Identify at least three evolutionary adaptations
possessed by leaves of plants in the rainforest to insure that they don�t
become damaged by heavy rain.
- Identify three examples of mechanisms by which plants
- Describe at least two carnivorous plants. Do they use a
passive (pitfall, flypaper) or active (snap) type of trap. Why did the
carnivorous habit evolve?
- What causes the formation/appearance of an annual ring?
- Complete the following table for each of the four major
requirements of photosynthesis.
||Where Obtained? (soil, air)
||Plant organ used to obtain the nutrient from the environment
(root, stem, leaf)
Challenge Questions: (bonus)
- Do all plants rely on photosynthesis for survival? If
not, can you name an exception?
- Design an experiment to demonstrate that minerals are
required for plant growth
