The "Nucleus" contains the genetic information of the cell in the form of deoxyribonucleic acid (DNA) or chromosomes and thus, controls cell growth and multiplication. It is also the site of DNA replication (formation of an identical copy of DNA).
While the "Golgi apparatus", or Golgi complex, functions as a factory in which proteins received from the ER are further processed and sorted for transport to their eventual destinations: lysosomes, the plasma membrane, or secretion.
I'm pretty sure it's deposition because the sediments in the water(soil) are building up on the rock.
A eukaryotic cell has a nucleus as well as membrane bound organelles such as the golgi apparatus, endoplasmic reticulum ect.
