Aging Cells

The passage explains how the processes of mitosis and meiosis change with age, affecting the body’s ability to repair tissues and reproduce. In youth, mitosis functions with precision, ensuring accurate cell division and tissue repair, while meiosis creates healthy reproductive cells. However, as humans age, mitotic efficiency declines, leading to issues like increased susceptibility to mutations. Meiosis also becomes less effective, resulting in a higher likelihood of genetic disorders in offspring.

This passage helps students understand how biological processes evolve over time, enhancing their ability to make connections between scientific concepts and real-world phenomena. The text promotes critical thinking by encouraging students to reflect on the relationship between aging and cellular functions. It expands vocabulary by introducing terms related to genetics and aging, while the structured comparison of cellular processes across life stages develops reading comprehension. The passage also strengthens grammar skills through its use of complex sentence structures.
