Identify a structure found in the form of vesicles, tubules and lamellae.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. Mesosomes
Mesosomes are structures found in prokaryotic cells, appearing in the form of vesicles, tubules, and lamellae. They are infoldings of the plasma membrane and are thought to play roles in cellular processes such as respiration, DNA replication, and cell division. Although their exact function is still debated, mesosomes are often observed in bacteria and are believed to increase the surface area of the membrane. Other options like plastids, lysosomes, and cytoplasm do not exhibit these specific structural forms. Plastids are found in plant cells, lysosomes are membrane-bound organelles in eukaryotic cells, and cytoplasm is the cell’s gel-like substance.
Other Options:
-
Plastids: Organelles like chloroplasts, not typically described as vesicles/tubules/lamellae.
-
Lysosomes: Membrane-bound vesicles involved in digestion but not usually in these forms.
-
Cytoplasm: The jelly-like substance inside the cell, not a structured organelle.
