A continuous culture system maintains cells in exponential growth by continuously adding fresh nutrients and removing waste products.

Evaluate the given options

• Flow cytometer: An instrument used to detect and measure physical and chemical characteristics of a population of cells or particles.
• Batch: A closed-system culture where nutrients are not renewed and wastes are not removed.
• Chemostat: A bioreactor to which fresh medium is continuously added, while culture liquid containing remaining nutrients, metabolic end products, and microorganisms is continuously removed to keep the culture volume constant.
• RT-PCR: A laboratory technique combining reverse transcription of RNA into DNA and amplification of specific DNA targets using polymerase chain reaction.

Select the correct term
