In your own words - grasses are flowering plants but many do not have colorful flowers. What mechanism do they use to spread their pollen
Scientists have studied plant populations that have moved into areaswith low herbivory compared to the plant’s previous habitat. Aftermany generations in the new habitat, the plants produce fewerdefensive chemicals and grow larger than plants in the ancestralpopulation. How does natural selection explain these observations?(Hint: Producing defensive chemicals uses energy.)
Some people have stated that the flowering plants "invented" the bees. What do you think? To answer this question think about the co-evolution of plants and their pollinators. Make sure you can support your position.

Compare to a plant with a mutation that allows it to do phototropism more quickly than other plants. Explain in terms of natural selection.arrow_forwardA plant biologist observed a peculiar pattern when a tropical shrub was attacked by caterpillars. After a caterpillar ate a leaf, it would skip over nearby leaves and attack a leaf some distance away. Simply removing a leaf did not deter caterpillars from eating nearby leaves. The biologist suspected that an insect-damaged leaf sent out a chemical that signaled nearby leaves. How could the researcher test this hypothesis?arrow_forward
- What is the purpose of the fruit we (and other animals) eat, from the plant's perspective? Group of answer choices To create something attractive to pollinators. To create a food item that ensures humans will continue to farm them. To bring in more than one type of pollinator. To entice us to eat the seeds contained inside the fruit, and thus disperse the seeds.arrow_forwardPlants that colonize disturbed areas (colonizing species aka weeds) have to disperse their offspring widely so that some seeds will land in appropriate habitat.
