Cell Lab

Cell is the basic biological unit that satisfies the living conditions. The earlier form of the cells is called prokaryotic, which lacks nucleus and membrane-bound organelle. A cell with nucleus and membrane-bound organelle is called eukaryotic, which leads to the diversity of the life on the earth. Over the time through the evolution of the life, some organisms are unicellular, and the others, multicellular. People often insinuate, including myself, that multicellular organisms are more advanced and successful than unicellular organisms.

Unicellular organisms have all living functions: respiration, digestion, reproduction, and excretion, within one cell. But the multicellular organisms, groups of cells specialized functions each, no one cell from the multicellular organisms can survive on its own.

Even though the multicellular organisms advanced from the unicellular organisms, the unicellular organisms are not necessarily inferior to the multicellular organisms. The organisms themselves as a group of cells, the multicellular organisms can be advanced, because each cells have their specialized function, but as one cell, the unicellular organisms have more complex characteristics and one cell can survive itself.
