What is the main difference between unicellular and multicellular organisms?

Unicellular organisms contain millions of cells, while multicellular organisms have a single cell.

In unicellular organisms, a single cell carries out all basic functions, while in multicellular organisms, different groups of cells are specialized to carry out specific functions. (correct)

Unicellular organisms are more efficient at carrying out specific functions compared to multicellular organisms.

Multicellular organisms have a single cell that carries out all basic functions, while unicellular organisms have millions of specialized cells.

How are cells in multicellular organisms specialized to carry out specific functions?

They form tissues that work together efficiently. (correct)

They are not specialized in multicellular organisms.

They carry out all basic functions individually.

They are grouped together based on structure.

What defines a tissue in multicellular organisms?

A group of cells that are not similar in structure.

Cells specialized to carry out a particular function. (correct)

Cells working independently without coordination.

A cluster of cells that carry out all basic functions.
