"Angiosperms are plants that have fruit. The cycle of making the fruit never stops. First there is a flower, a bee comes and eats the pollen. Some of it will get knocked down in the flower's ovary. Then the flower's ovary will start to swell up. It will make an apple let's say. An animal will come and eat the apple. The animal will either just leave the part of the apple with the seeds, or some of the seeds will make it through the animal's digestive system and get pooped out. The seeds will make a new plant and the plant will grow a flower and everything will happen again and again."
Hope explains angiosperms... and that is a fake smile. ;)
