Answer:
1. Angiosperms develop unique reproductive organs known as flowers. Flowers contain ovaries, witch surround and protect the seeds.
2. The main parts of a flower are the sepals and petals, which protect the reproductive parts: the stamens and the carpels. The stamens produce the male gametes in pollen grains. The carpels contain the female gametes (the eggs inside the ovules), which are within the ovary of a carpel.
3. All angiosperms have flowers at some stage in their life. ...
Angiosperms have small pollen grains that spread genetic information from flower to flower. ...
All angiosperms have stamens. ...
Angiosperms have much smaller female reproductive parts than non-flowering plants, allowing them to produce seeds more quickly.
4. When an individual organism increases in size via cell multiplication and remains intact, the process is called "vegetative growth". However, in vegetative reproduction, the new plants that result are new individuals in almost every respect except genetic.
5. Fruits are produced only by flowering plants (angiosperms). Following pollination of the flower, the fertilized ovules develop into seeds while the surrounding ovary wall forms the fruit tissue, or pericarp.
Explanation:
Answer:
Prokaryotes play several roles in the nitrogen cycle. Nitrogen-fixing bacteria in the soil and within the root nodules of some plants convert nitrogen gas in the atmosphere to ammonia. Nitrifying bacteria convert ammonia to nitrites or nitrates. ... Denitrifying bacteria converts nitrates back to nitrogen gas.
