protoplast

protoplast
Danh từ
Số nhiều: protoplasts

This term is primarily used in specialized biological and botanical contexts. In modern laboratory settings, it refers specifically to a plant cell that has been stripped of its cell wall, typically through enzymatic digestion, to allow for genetic manipulation or the study of membrane permeability.

In an evolutionary or historical biological context, the term takes on a more theoretical meaning, referring to a hypothetical primitive organism. This usage is less common in contemporary textbooks than the cellular definition but remains relevant in discussions regarding the origins of life.
