Step by step
Solved in 2 steps
- Which of the following statements is false? a. Ferns produce seeds inside sori. b. Conifers do not produce fruits. c. Both gymnosperms and angiosperms produce pollen. d. Only angiosperms produce flowersThere are four phyla that belong to the gymnosperm. Describe Phylum Ginkgophyta and explain why and how Ginkgo biloba became the only surviving species. What is the importance of this species to man?Although there are fewer than 1,000 species of gymnosperms,the group is still very successful in terms of its evolutionary longevity,adaptations, and geographic distribution. Explain.
- A slight change in a plant species’ flower structure might favor a different pollinator. How might such a change in flower structure lead to a new plant species? How does coevolution between flowering plants and animal pollinators help explain the huge diversity of angiosperms?Most angiosperms incorporate the assistance of animals in their reproductive cycle. This is a major advancement that gave them an advantage over other plant lineages and helped them become the dominant type of plant on Earth today. Which of the following steps in the reproduction of angiosperms do animals assist with? Check all that apply. A. Seed dispersal B. Pollination C. FertilizationAngiosperms ( flower bearing ) plants developed after gymnosperms ( cone bearing ) plants during the Mesozoic era Which of the following is a benefit to plants developing the ability to have flowers over cones ? ANSWER CHOICES ARE IN THE PHOTO. thanks.
- What evolutionary advantages do seed provide over spores? What was early gymnosperm ecology like? What ecological role did gymnosperms perform as the dominant terrestrial plant type 250 million years ago? what were did angiosperms begin to replace gymnosperms as the new dominant plant type in terrestrial ecosystemsMost angiosperms incorporate the assistance of animals in their reproductive cycle. This is a major advancement that gave them an advantage over other plant lineages and helped them become the dominant type of plant on Earth today. Which of the following steps in the reproduction of angiosperms do animals assist with? Check all that apply. Pollination Fertilization Seed dispersalDouble fertilization evolved independently in gnetophytes and in flowering plants. Name two other features usually associated with angiosperms that evolved independently in gymnosperms.
- Which of the following incorrectly pairs a sporophyte embryo with its food source? * A. Moss embryo-archegonium and gametophyte plant B. Fern embryo-female sporophyte surrounding archegonium C. Pine embryo-female gametophyte tissue in nucellus D. Corn embryo-3N endosperm tissue in seedThe 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?Are gymnosperms heterosporous or homosporous? Explain what this means. What are the evolutionary “advances” represented by the seed?
