Quizplus · Accepted Answer

A flow cytometer is ideal for counting cells and determining cell size because it uses laser technology to measure the physical and chemical properties of each individual cell. It can also differentiate between living and dead cells by staining them with fluorescent dyes. Coulter counters are also capable of counting cells but may not provide as much information about cell viability or size. SEM and plate counts are not suited for this purpose. Methylene dye indicator is a type of stain used to visualize cells but does not provide precise cell counting or sizing information.
