Describe the process of cell differentiation in multicellular organisms.

• Cell differentiation involves cells losing their specialized functions in multicellular organisms.

• Cell differentiation is a process that occurs only in unicellular organisms.

• Cell differentiation is the process of cells becoming identical in multicellular organisms.

• Cell differentiation is the process by which cells become specialized to perform specific functions in multicellular organisms.

How do unicellular organisms obtain nutrients?

• By consuming other unicellular organisms

• By absorbing nutrients through their skin

• Through photosynthesis

• Through diffusion, osmosis, and active transport across their cell membranes.

Why do multicellular organisms have a higher level of organization compared to unicellular organisms?

• Specialization and coordination of cells lead to higher organization levels in multicellular organisms.

• The level of organization in multicellular organisms is lower due to their larger size.

• Multicellular organisms have a higher level of organization because they lack specialization.

• Unicellular organisms have a higher level of organization due to their simplicity.
