Step 1:
: Understand the question and recognize that it is a biological concept question about the location of lysosomes in different types of cells.

Step 2:
: Recall the definition of lysosomes.

Lysosomes are membrane-bound organelles found in eukaryotic cells. They contain enzymes that break down waste materials and cellular debris.

Step 3:
: Review the types of cells mentioned in the question.

Eukaryotic cells have a true nucleus and membrane-bound organelles, while prokaryotic cells do not have a true nucleus or membrane-bound organelles.

Step 4:
: Based on the gathered information, we can now determine the presence of lysosomes in each type of cell.

Step 5:
:

For eukaryotic cells (A): Lysosomes are present in eukaryotic cells as they are membrane-bound organelles that contain enzymes for breaking down waste materials and cellular debris.

Step 6:
:

For prokaryotic cells (B): Lysosomes are not present in prokaryotic cells since they do not have membrane-bound organelles.

Step 7:
:

For both eukaryotic and prokaryotic cells (C): Lysosomes are not present in both types of cells because, as explained in step 6, prokaryotic cells do not have membrane-bound organelles.

Step 8:
:

For neither eukaryotic nor prokaryotic cells (D): Lysosomes are present in eukaryotic cells, so this option is incorrect.

Final Answer

Lysosomes are found in eukaryotic cells (option A).
