ANATOMY

Detailed explanation-1: -The correct option is B False. Multicellular organisms: The organisms which are made up of more than one cell (two to billions of cells) are called multicellular organisms. The cells in multicellular organisms are of different types, each type performs specific functions.

Detailed explanation-2: -Cells function differently in unicellular and multicellular organisms. A unicellular organism depends upon just one cell for all of its functions while a multicellular organism has cells specialized to perform different functions that collectively support the organism.

Detailed explanation-3: -Cells of various types have different functions because cell structure and function are closely related. It is apparent that a cell that is very thin is not well suited for a protective function. Bone cells do not have an appropriate structure for nerve impulse conduction.

Detailed explanation-4: -Detailed Solution. The incorrect statement is All cells are identical. Multicellular organisms, in contrast to unicellular organisms, are organisms which consist of more than one cell.

Detailed explanation-5: -Being multicellular allows the organism to be larger and to have cell differentiation so different types of cells to carry out different tasks.
