"But some creatures have just a single cell, like an amoeba. They
are called unicellular organisms. Other creatures, like us human
beings, are collections of cells. These are called multicellular
organisms. Multicellular organisms can range in size from brown
algae to large animals like elephants and whales, which have
trillions of cells."
What can be concluded about cells based on this information?
A Unicellular organisms were once part of collections of cells.
B. Cells in multicellular organisms are stronger than unicellular organisms.
C. Cells can only support life if they are part of a multicellular organism.
D. Some cells can support life independently. Other cells support life collectively
