What advantages does skunk cabbage derive from this adaptation? How may this impact other species? Would you classify this plant and EXOthermal and explain your answer.
Lignin and vascular tissue first evolved in relatives of club moss, and some extinct species stood 40 meters (130 feet) high. Explain how the evolution of vascular tissues and lignin would have allowed a dramatic increase in plant height. How might being tall give one plant species a competitive advantage over another?
Suppose that plants in the San Francisco Bay area and in southern Chile share a common seed dispersal method. Scientists determine that the evolutionary divergence of these plants happened long before this seed dispersal method arose in each plant. What term relates the seed dispersal method of the San Francisco Bay plant to the seed dispersal method of the southern Chile plant? Explain your answer.

- In some species, sepals look like petals, and both are collectively called “tepals.” Suggest an extension to the ABC hypothesis that could account for tepals.arrow_forwardImagine that you wanted to know if speciation rate in plant groups is linked to whether the plants are pollinated by bees or hummingbirds. To do this, you identified 20 genera of angiosperms that contained species pollinated by both types of animals. There were substantially more species in the groups that were pollinated by bees. Which of the following conclusions are most consistent with your data? A. Hummingbirds promoted speciation less than did bees. B. Hummingbirds promoted speciation more than did bees. C. Each genus should first be split into two new genera. D. The rates of speciation are independent of pollinator type.arrow_forwardA) Using the information/image provided, why could the researchers rule out pollinator selection as a reason for flower color variation? B) What must be true about the flowers in Boechera stricta? A) Plants have both male and female flowers that are reproductively mature at the same time. B) Plants have both male and female flowers that are reproductively mature at different times. C) Plants produce either male or female flowers C) If the scientists' hypothesis is true, what type of herbivore defense is flower pigmentation in this mustard? either constitutive or induciblearrow_forward
- Discuss how adaptations allowed plants to move from an aquatic environment to the variety of habitats they inhabit today. Maybe, start out by discussing single celled algae and include the transition from prokaryotes to eukaryotes. Then explain why those traits are adaptive, and how they arose. Don't forget the role of natural selection in adaptation.arrow_forwardExplain why humans follow a Type I survivorship curve, birds follow a Type II survivorship curve, and angiosperms follow a Type III survivorship curve. How do the traits of these species produce the associated survivorship curve? do not copy from cheggarrow_forwardWith named plant species as experts, discuss various organ modifications in plants, clearly stating the benefits such modifications confer in plants that have them?arrow_forward
