Question

what is one reason mentioned for why individuals grow larger over time?
\mitosis\
\photosynthesis\
\cell division through meiosis\
\apoptosis\

Explanation:

Mitosis is a type of cell - division where a single cell divides into two identical daughter cells. This process increases the number of cells in an organism, contributing to growth. Photosynthesis is used by plants to convert light energy into chemical energy. Meiosis is for the production of gametes (sex cells) and not related to general body growth. Apoptosis is programmed cell - death, which is not a growth - promoting process.

Answer:

"Mitosis"
