How des the unillular grow?

Unicellular organisms grow primarily through a process called cell division, where a single cell replicates its genetic material and divides into two daughter cells. This process, often through binary fission in prokaryotes, allows the organism to increase in size and number. Additionally, unicellular organisms can also grow by absorbing nutrients from their environment, which helps them increase their cellular mass before dividing. Overall, growth in unicellular organisms is closely tied to their reproductive processes.
