Which one among the following statements regarding cell is not correct ?

Statement 4 is incorrect because multicellular organisms are composed of diverse cell types specialized for different functions. While a tissue is defined as a group of similar cells performing a common function [t1], the body as a whole contains over 200 distinct cell types, such as neurons, muscle cells, and blood cells [t1][t3]. Statement 1 is correct as cell shape and size are intrinsically linked to their specific roles; for example, elongated neurons facilitate message transmission [c2][t4]. Statement 2 is correct because certain cells, like Amoeba or white blood cells, can change their shape. Statement 3 is correct as cells are the basic functional units with the capacity to perform vital life processes individually or cooperatively [c5][t7]. Differentiation ensures that cells specialize morphologically and physiologically to adapt to their specific environmental or functional requirements [t2][t8].
