Answer:
Aerobic metabolism is the most efficient way of producing ATP; it produces significantly more ATP for each molecule of glucose than anaerobic metabolism. Although the primary source of ATP in aerobic metabolism is carbohydrates, fatty acids and protein can also be used as fuel to generate ATP.
<span>Similarities</span> between Gymnospermes and Angiospermes:
<span>·
</span>Having seed-Gymnospermes and Angiospermes are types of plants bear seeds. They belong
to a single class known as Spermatophyta. Spermatophyta or seed
plants are those <span>plants that produce seeds.</span>
<span>·
</span>Diferentiation- The sporophyte (diploid
multicellular stage in the life cycle of a plant) of both,<span> Gymnospermes and Angiospermes,</span> is differentiated into root, stem, and leaves.
Differences between Gymnospermes and Angiospermes:
<span>·
</span>Seed-Although both
have seeds, differences between them are huge. Gymnospermes have bare, non-encased seeds. The term
"gymnosperm" in Greek means "naked seeds".
On the other hand, seeds of Angiospermes are enclosed within an ovary,
usually in a fruit.
<span>·
</span>Pollination- In Gymnospermes, the pollination is
by wind, unlike most Angiosperms, who use insects, mammals or birds. Gymnosperm flowers are often difficult to spot
because they are not out to attract flying pollinators.
