A single-celled organism carries out all of its life processes in one cell.
Which statement explains why cell differentiation benefits a multicellular organism?
Every cell can carry out every function, so losing one cell does not matter.
Cells divide more rapidly by mitosis, so the organism grows to a larger size.
Cells are adapted for different functions, so each function is done more efficiently.
Cells become genetically different, so the organism can adapt to its environment.
194 exam-style questions on OCR GCSE Biology 2.1 Supplying the cell, covering 2.1.1 Transport across cell membranes, 2.1.2 Mitosis and the cell cycle, 2.1.3 Importance of cell differentiation, and 2.1.4 Stem cells. Each one has a worked solution and a mark scheme showing where the marks go.
