UP CPMTUP CPMT 2010Cell : The Unit of Life
Solution:
The term plasma membrane was originally used by Nageli and Cramer $(1855)$ for the membranous covering of the protoplast. The same was named plasmalemma by Plowe $(1931)$. Plasmalemma or plasma membrane was discovered by Schwann $(1838)$. Membranes also occur inside the cytoplasm of eukaryotic cells as covering of several cell organelles like nucleus, mitochondria, plastids, lysosomes, Golgi bodies, peroxisomes, etc.
