Virchow was correct when he concluded that cells arise from others cells, i.e., new cells are born through the division of one cell into two through the process of mitosis. The need for new cells continues throughout our lives, but it is greatest in early life. A fertilized egg divides into two cells, which give rise to four, and those give rise to eight, and then to 16, and 32, and 64, and so on. In a fully grown adult, of course, the rate of cell proliferation is much less, and under normal circumstances, cell division in an adult takes place only when signals indicate the need to replace cells that have been lost, damaged, or worn out. Basically when your young so is your cell and ask you get older they get stronger

Answer:
Nitrogen fixing bacteria
Explanation:
Nitrogen-fixing bacteria are the microbial organisms that play an important role in the conversion of atmospheric nitrogen gas into reactive nitrogen such as ammonia, nitrogen oxide, and nitrous oxide. These types of bacterias are comprised of an enzyme known as the 'nitrogenase enzyme' that allows the nitrogen gas to mix with hydrogen and eventually produces ammonia.
This ammonia is then concentrated in the soil and is later taken up by the plants which are highly essential for them as they ammonia are their main source of nitrogen. This helps in the growth, development, and expansion of the overall plant body.
