Think about the Coniferophyta and the Magnoliophyta of this chapter. Which has more families, genera, and species? Which has more diversity of body types? Which has species in the greatest number of habitats (deserts, forests, rain forests, underwater, grasslands, marshes, epiphytic habitats, and so on). Which group originated earlier in evolution, and which originated later? The older group has had more time to diversify. Is it the more diverse of the two?

Bullet items are selections for the question above it 1.The seedless vascular plants not only include well-known plants such as ferns but also groups of plants called horsetails and club mosses. These plants originally arose after the bryophytes. Which of the following statements describes why seedless vascular plants are better adapted to dry land than the bryophytes? Seedless vascular plants have spores that can distribute on the wind. Seedless vascular plants have larger leaves, or fronds, that are more effective in absorbing nutrients from the environment. Seedless vascular plants have vascular tissue and roots to effectively absorb and distribute water and nutrients throughout the plant. 2. However, seedless vascular plants are still heavily dependent on water for reasons other than keeping hydrated. Which of the following statements correctly explains how seedless vascular plants are still dependent on water? Seedless vascular plants require water…
Bryophytes can be found in every type of habitation, except in the oceans, thus reflecting the progressive species expansion occurred along the evolution. However, bryophytes rarely succeed in the ecosystem. Why do you think so? Give three reasons.
Seeds and pollen grains are key adaptations for life on land. These adaptations relate to reproductive success and survival advantages. The following questions require you to explain some of these adaptations. A. Contrast sperm delivery in seedless plants with sperm delivery in seed plants. (5-6 sentence) B. Discuss at least one feature of seed plants that contributed to their success on land in contrast with seedless plants. (2-3 sentences) C. Flowering plants (Magnoliophyta) are the most successful of all plant groups in terms of their species diversity and ubiquity across habitat types. Climate warming is causing shifts in the timing of life history events for many species. Discuss how climate warming may influence reproductive strategies employed by flowering plants. (2-3 sentence)

Which of the following statements is NOT true? Answers Bryophytes and ferns have the same type of life cycle Bryophytes were the first land plants In ferns, the dominant generation is the diploid stage organism The adaptation of seeds allowed plants to sexually reproduce on land without the need for water All of the above are true Please explain which one is correct.
Seedless Plants Mosses and Other Bryophytes Write True if false 1. Mosses and their relatives belong to a group called Bryophytes 2. Bryophytes stay small because they lack true vascular tissue. 3. The gametophyte is the dominant stage of bryophytes. 4. Bryophytes must live in places where there water for at least part of the year because, for fertilization to occur, eggs must swim. ______________5. A fern is a seedless vascular plant 6.
