Study Notes
Mesosomes in Bacteria
- French scientist Étienne Roux first observed mesosomes in bacteria in 1914.
Structure and Function of Mesosomes
- Mesosomes are also known as chondrioids and are invaginations of the bacterial cell membrane.
- Initially, mesosomes were thought to be involved in cellular respiration, similar to mitochondria in eukaryotic cells.
Current Understanding of Mesosomes
- Current research suggests that mesosomes are not directly involved in cellular respiration, but rather have other functions in bacterial cells.
Forms of Mesosomes
- Mesosomes can exist in various forms, including vesicles, tubules, and lamellae, which are all extensions of the bacterial cell membrane.
