<span>An advantage for the angiosperm approach to the formation of nutritive tissue is in energy conservation.</span> <span>The nutritive tissue is formed via double fertilization in Angiosperms. The advantage of double fertilization is that the plant does not invest energy in seed nutritive tissue until after an egg has been fertilized. This means that endosperm (nutritive tissue) starts to develop and store nutrients after it has been fertilized by a sperm cell.</span> Another advantage is that the endosperm nucleus is very active and <span>divides rapidly, so it forms the nutritive tissue very quickly.</span>
Answer:
Pangenesis
Explanation:
The theory of 'pangenesis' was proposed by Darwin to explain the process of inheritance of genetic traits from one generation to next. According to this theory, gemmules are the tiny particles produced by all the somatic cells of the body of living beings. These gemmules are also called pangene. Blood carries gemmules from all the body cells to the gonads. These gemmules from all the somatic cells form germ cells in gonads.
Pretty much any research requires good observational skills. You have to be able to observe and record what is happening. Obviously the more you can see, the more you can record.
