Which term describes a permanent increase in size and dry mass due to cell growth?

Explanation:
Growth describes a permanent increase in size and dry mass as cells divide and synthesize more material. This is why it’s the best term: it directly refers to the actual build-up of new cellular matter and the enlarged size that results, not just processes that provide energy (respiration), movements of water (osmosis), or taking in food (ingestion). Respiration powers activities including growth but does not itself describe the change in size. Osmosis can cause cells to swell or shrink temporarily due to water movement. Ingestion is about taking in substances, which supports growth but isn’t the growth process itself.
