Question

what makes eukaryotic cells more complex than prokaryotic cells? their lack of any organelles having lots of cytoplasm presence of a true nucleus

Explanation:

To determine what makes eukaryotic cells more complex than prokaryotic cells, we analyze each option:

• "their lack of any organelles": Prokaryotic cells have fewer organelles, while eukaryotic cells have membrane - bound organelles. So this option is incorrect.
• "having lots of cytoplasm": The amount of cytoplasm is not the key factor that makes eukaryotic cells more complex. Prokaryotic cells also have cytoplasm. So this option is incorrect.
• "presence of a true nucleus": Eukaryotic cells have a true nucleus (with a nuclear membrane enclosing the genetic material), while prokaryotic cells have a nucleoid (genetic material not enclosed in a membrane). The presence of a true nucleus and other membrane - bound organelles allows for more complex cellular organization and functions in eukaryotic cells.

Answer:

C. presence of a true nucleus (assuming the options are labeled A, B, C with A being "their lack of any organelles", B being "having lots of cytoplasm", and C being "presence of a true nucleus")
