Multiple Choice

Which of the following statements about the corona and frenulum is correct?

The corona is a membrane-bound organelle found in eukaryotic cells, and the frenulum is responsible for protein synthesis.

Both the corona and frenulum are types of cellular vesicles involved in intracellular transport.

The corona is the rounded border at the base of the glans penis, while the frenulum is a fold of tissue on the underside of the penis connecting the glans to the shaft.

The corona and frenulum are both found exclusively in plant cells and are involved in photosynthesis.

Verified step by step guidance

Step 1: Begin by identifying the anatomical structures mentioned in the problem: the corona and the frenulum. These are terms related to the male reproductive anatomy, not cellular organelles or plant structures.

Step 2: Understand the corona. The corona refers to the rounded border at the base of the glans penis, which is the bulbous end of the penis. It is a distinct anatomical feature of the external male genitalia.

Step 3: Understand the frenulum. The frenulum is a fold of tissue located on the underside of the penis. It connects the glans penis to the shaft and plays a role in sensitivity and movement during sexual activity.

Step 4: Eliminate incorrect options. The first option incorrectly describes the corona and frenulum as cellular organelles, which is not accurate. The second option incorrectly categorizes them as vesicles involved in intracellular transport. The fourth option incorrectly states that they are exclusive to plant cells and involved in photosynthesis, which is biologically incorrect.

Step 5: Conclude that the correct statement is: 'The corona is the rounded border at the base of the glans penis, while the frenulum is a fold of tissue on the underside of the penis connecting the glans to the shaft.' This aligns with the anatomical definitions of these structures.
