Final answer:
The false statement regarding cell division is that it allows unicellular organisms to adapt to changing environments. Cell division is actually the method by which unicellular organisms reproduce, and for multicellular organisms, it is crucial for growth, repair, and the formation of specialized cells.
Step-by-step explanation:
The statement that is FALSE regarding the importance of cell division in unicellular or multicellular organisms is: "c) Cell division in unicellular organisms allows them to adapt to changing environments."
While it is true that cell division is crucial for both unicellular and multicellular organisms, the primary role of cell division in unicellular organisms is for reproduction. These organisms reproduce by dividing into two new cells, each of which is a replica of the parent. This process doesn't inherently lead to adaptation, although genetic variations that may occur during division could contribute to adaptation over time.
In multicellular organisms, cell division plays more diverse roles. It is essential for growth and repair of tissues, as well as for the formation of specialized cells and tissue via a process known as differentiation. During development, tightly regulated cell division results in the formation of the many different types of cells and tissues that make up the organism's body.
