3. Which of the following is CORRECT about comparing an onion cell and a human skin cell？Group of answer choicesboth cells have lysosomesboth cells have cell wallonion cell does not have nucleoid while human skin cell doesonion cell has a central vacuole while human skin cell does not

The correct answer is: both cells have lysosomes and onion cell has a central vacuole while human skin cell does not.

Here's why:

1. Both cells have lysosomes: Lysosomes are organelles that contain digestive enzymes. They digest excess or worn-out organelles, food particles, and engulfed viruses or bacteria. Both plant cells (like an onion cell) and animal cells (like a human skin cell) have lysosomes.

2. Both cells have cell wall: This is incorrect. Only plant cells (like an onion cell) have a cell wall. Animal cells (like a human skin cell) do not have a cell wall.

3. Onion cell does not have nucleoid while human skin cell does: This is incorrect. Both plant cells (like an onion cell) and animal cells (like a human skin cell) have a nucleus, not a nucleoid. Nucleoids are found in prokaryotic cells, not eukaryotic cells like plant and animal cells.

4. Onion cell has a central vacuole while human skin cell does not: This is correct. Plant cells (like an onion cell) have a large central vacuole that stores water, nutrients, and waste products. Animal cells (like a human skin cell) do not have a central vacuole. They have smaller vacuoles throughout the cell.
