Biology
The gelatinous, proteinaceous protective covering of a bacterial cell is termed as :
- Plasmalemma
- Sheath
- Cell wall
- Capsule
Answer
Capsule
Reason — The cell wall of a bacterium cell is surrounded by a gelatinous or proteinaceous 'capsule'. Plasmalemma refers to the cell membrane. Sheath is a broader term used for some filamentous bacteria, not specifically the typical protective gelatinous layer. Cell wall is a rigid structural layer, not gelatinous.
