Cells #2

Unicellular and multicellular organisms would both perform which processes?

• making food and removing waste

• specializing cells and taking in nutrients

• growing and reproducing

• migrating and finding shelter

• are unicellular

• are multicellular

• make their own food

• have specialized cells

Multicellular organisms have developed internal transport systems because

• internal cells are too far away to exchange substances with the external environment

• external cells must travel to internal cells to exchange materials

• internal cells perform all life processes

• surface cells perform all life processes
