33. Compare and contrast reproduction in gymnosperms and angiosperms and explain why angiosperms have evolved to be the most diverse group of plants on earth today

Expert Solution

Gymnosperms:
1. Plants with naked seeds
2. Embryophytic plants
3. Tracheophytic plants (Vessels are absent)
4. Archegoniate plants
5. Ovary is absent
6. Fruits and flowers are absent
7. Double fertilization does not occur
8. Anemophilous pollination

Angiosperms
1. Plants with closed seeds
2. Embryophytic plants
3. Tracheophytic plants (Vessels are absent)
4. Non-archegoniate plants
5. Ovary is present
6. Fruits and flowers are present
7. Double fertilization occurs
8. Diverse pollination agents

Angiosperms are the most diverse plants on earth today. Their dominance is due to several reasons.
i. Their vascular tissue contains vessels that are efficient in water and nutrient transport
ii. Their seeds are enclosed so that they can be dispersed to new geographical regions
iii. Fruits and endosperm help in proper seed development
iv. Flowers ensure pollination by diverse pollinating agents (Abiotic: Water and air; Biotic: Insects, animals, and birds)

Compare and contrast asexual and sexual reproduction: what are the principle advantages and disadvantages of each?...

Compare and contrast asexual and sexual reproduction: what are the principle advantages and disadvantages of each? Why do nearly all living organisms have some form of sex during their life cycle? Explain the two sources of genetic diversity that result from meiosis. Why is crossing over (recombination) especially important for the adaptive evolution of a species.

Compare and contrast taste and smell. For example, why is it that taste appears to have a small set of basic qualities, while smell does not? You should explain the basic theories underlying the perception of each, including how specificity coding vs. population coding apply to each. You should also include in your discussion how the two combine to produce flavor.
