This is evident in the process of morphogenesis, in which the correct placement and differentiation of cells is essential for the formation of complex structures like organs and limbs. A and C are incorrect because animals cannot carry out photosynthesis, and their cell walls are not made of chitin but may be absent altogether (in the case of animal cells). Option B is also incorrect as it does not apply to all animals as some go through alternative life cycle stages, such as adult polyps and medusae in cnidarians.
