Question

The arrangement of cells is comparable to bricks of building. Why?

Answer 1

Although cells are living structures and bricks are non-living, the arrangement of cells is comparable to bricks of building because like buildings made of same bricks have different shapes, sizes and designs, similarly organisms are made up of same cells but are different from each other. Organism made of single cell are called unicellular organisms whereas, organisms made up of more than 1 cell are called multicellular organisms.
