Which biological events took place during the Paleozoic Era and the Mesozoic Era? O During the Paleozoic Era, three mass extinctions occurred which led to the colonization of land by plants, while during the Mesozoic Era, gymnosperms became the dominant plant life. O During the Mesozoic Era, five mass extinctions occurred which led to the colonization of land by plants, while during the Paleozoic Era, angiosperms became the dominant plant life. O During the Mesozoic Era, three mass extinctions occurred which led to the colonization of land by plants, while during the Paleozoic Era, gymnosperms became the dominant plant life. O During the Paleozoic Era, five mass extinctions occurred which led to the colonization of land by plants, while during the Mesozoic Era, angiosperms became the dominant plant life.

What is the correct order of appearance in the fossil record, starting with the earliest: flowering plants, ferns, gymnosperms?
Review the life cycles of the three major plant groups (bryophyte or non-vascular plants, seedless vascular plants, and seed plants). Be able to identify the gametophyte and sporophyte generations in each plant group. Make one graph that shows patterns of changes in the following characteristics, as the different plant groups (bryophytes or non-vascular plants, seedless vascular plants, and seed plants) appeared or evolved on land through time. 1) size of the gametophyte generation 2) size of the sporophyte generation 3) biomass (amount of organic material) stored in the sporophyte 4) degree of dependence on water for fertilization Make sure the y- and x- axes of the graph, labels and title are included and correctly applied.
Insects are the most diverse group of multicellular organisms on Earth. Select each of the factors that are hypothesized to have contributed to this diversity. (Select Multiple) Select one or more: a. Incomplete metamorphosis O b. Evolution of wings c. Ability to fold wings over back O d. Coevolution with flowering plants (angiosperms) O e. Complete metamorphosis
How did the evolution of certain reproductive features allow early plants to invade the land? Answer the same question for animals.
Plants made the leap from water to land during the late Ordovician period (we think). In order to make it, various physical obstacles had to be overcome. Choose one adaptation and explore it further. What evidence do we have of this change? Are there specific fossils of plants that exhibit it? How do we think it may have developed? Not all of these changes occurred at the exact same time. Was your chosen adaptation one of the first or late to the game? including references are appreciated.
Although we do not know exactly what the first vascular plant looked like we can be very confident that it was similar to the fossil plant Cooksonia. Based on our understanding of Cooksonia, we can assume that the first vascular plant? Reproduced using seeds in strobili Had photosynthetic stems, not leaves Did not have branches Was dioecious

A paleontologist found the fossils of a Glossopteris fern in all the southern continents of the world, as shown by the image. Site where Glossopteris fossils were found The Glossopteris fern was a type of plant. What best explains the occurrence of this fern in so many different parts of the world? O The Glossopteris fern could grow in any type of soil. O All the southern continents were once part of a single supercontinent where the Glossopteris fern grew. O The Glossopteris fern used water from oceans as a source for reproduction. O All the southern continents had favorable climatic conditions for the growth of the Glossopteris fern. bp esc -> # % & 2 4 W e r t
If the stomata of bryophytes and of vascular plants are not an example of convergent evolution, what is an alternative explanation for their appearance in these groups?
How did the dramatic growth of seedless vascular plants during the Devonian and early Carboniferous period affect the Earth and other life forms? Explain.
Which two structures evolved though a series of changes in the reproductive biology among some heterosporous plants during the late Devonian period allowed spermatophytes (seed plants) to reduce or eliminate their dependence on water for gamete fertilization and development of the embryo and allowed them to colonize a much wider range of habitats?
The generation time of a tree species is likely to be 50 to 100 times longer than that of many species of herbivorous insects and parasitic fungi,so a tree’s potential rate of evolution should be slower. Why have trees, or other organisms with long generation times, not become extinct as a result of the potentially more rapid evolution of their natural enemies?
