Concept explainers
To determine: Whether seed dispersal by ants is an example for coevolution.
Concept introduction: Coevolution is the mutual evolutionary influence in which two species reciprocally adapt by totally depending on each other. A classic example for such evolutionary phenomenon is flowering plants and their pollinators in which they place beneficial evolutionary pressure on each other for changes in physiology, morphology, or habits.
To determine: The reason why seed dispersal by ants is an example for coevolution.

- Name four major ways human societies rely on seed plants.arrow_forwardForest grow and cover large areas due to the dispersal of pollen and seeds. True or false arrow_forwardIn wild columbine, flower morphology encourages crosspollination. However, during the middle of the receptive period of the stigma, self-pollination can occur if the flower was not previously pollinated. If cross-pollination occurs after selfpollination, then that pollen reaches the base of the style before the self-pollen. Discuss the adaptive significance of this reproduction strategy.arrow_forward
- Dry fruits, or seeds, with plumes or wings, are adapted by dispersal by ____? Fleshy fruits are adapted for dispersal by ____?arrow_forwardThe Cretaceous Period was marked by the increase in number and variety of angiosperms. Insects also diversified enormously during the same period. Can you propose the reason or reasons that could foster coevolution?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_forward
- Coevolution is most likely to involve/occur in a plant whose pollination is conducted by__________. Group of answer choices A specialist Impossible to predict Wind A generalistarrow_forwardProvide a full explanation for the adaptive radiation of insects and coevolution of insects and angiosperms (flowering plants) included pollination syndrome example. arrow_forwardThe process of _______________ in flowering plants involves one sperm cell fusing with an egg cell and one sperm cell fusing with two polar nuclei. (a) coevolution (b) germination (c) double fertilization (d) apomixis (e) pollinationarrow_forward
- Which of the following is the best example of coevolution?O A. Antibiotic-resistant strains of bacteria proliferate when antibiotics kill good bacteria and select for any cells resistant to that antibiotic.O B. Birds and bats both have wings, but these structures developed independently.O C. Sharks and dolphins look very similar, but sharks are a type of fish, and dolphins are a type of mammal.O D. Some plants that require pollination have developed ways to attract pollinators, such as brightly colored and fragrant flowers; pollinators have developed specializedstructures to obtain pollen and nectar from the plants.arrow_forwardIf there is a steep decline in the population of the major pollinators in an area, which of the following angiosperms would be most directly affected: aspen trees, pear trees, or dandelion plants? Why?arrow_forwardMention two strategies evolved to prevent self-pollination in flowers.arrow_forward
