Who called the living matter of the cell as protoplasm?A. PurkinjeB. VirchowC. HookeD. Khorana

The correct answer is A. Purkinje.

Explanation:

The term "protoplasm" was coined by the German scientist Johannes Evangelista Purkinje in 1839. Purkinje used this term to refer to the living substance inside the cell, which is distinct from the cell's non-living components such as the cell wall and the vacuole. Protoplasm includes both the cytoplasm and the nucleus and is considered the fundamental living material within the cell, where various cellular activities take place.

Virchow (B) is known for his work on cell theory, stating that "All cells come from pre-existing cells."
Hooke (C) is famous for discovering cells by observing a slice of cork under a microscope.
Khorana (D) was a biochemist known for his work on the genetic code, not for coining the term "protoplasm."
Thus, the correct answer is A. Purkinje.
