Characteristics of Living Things As part of its growth, a single-celled organism undergoes cell division, a process called mitosis in eukaryotic cells. During cell division, the single cell replicates its genetic material and then splits into two daughter cells, each containing an identical set of genetic information. This division allows the organism to increase its cell number and eventually grow in size. Single-celled organisms primarily rely on cell division for growth and reproduction, whereas multicellular organisms grow through the division and differentiation of specialized cells. What does a single-celled organism do as part of its growth? It becomes a smaller cell. It divides into more cells in cell division. It transforms into an organism.

Answer 1

As part of its growth, a single-celled organism divides into more cells in cell division. This process, known as mitosis, allows the organism to replicate its genetic material and increase its cell number, which contributes to its growth.
