An example of mitosis at work is a plant root ______.

A plant root is an excellent example of mitosis at work because it is a region of active growth where new cells are continually produced. At the tips of plant roots, specifically in the meristematic tissue, cells undergo mitosis to allow the root to grow longer and expand its reach in the soil for nutrients and water. This process is crucial for plant development, contributing to both the growth of the root system and overall plant health. As cells divide through mitosis, they ensure that the plant can adapt to its environment, repair damaged tissues, and support new growth, exemplifying the importance of cellular division in the life cycle of plants.
