4.

Eukaryotic cells are more complex than prokaryotic cells, with membrane-bound organelles enabling diverse functions. The plasma membrane regulates substance passage, and the nucleus is likened to the brain of the cell.

Explanation:

Eukaryotic cells are typically larger and more complex than prokaryotic cells, containing membrane-bound organelles that enable them to perform a wide range of functions. While prokaryotic cells lack a nucleus and membrane-bound organelles, eukaryotic cells possess these structures, such as mitochondria, endoplasmic reticulum, and lysosomes, enhancing their functionality.

The plasma membrane in a eukaryotic cell serves to regulate the passage of substances into and out of the cell, aiding in maintaining homeostasis by controlling what enters and exits the cell.

In the analogy provided, a lysosome functions like a vacuum cleaner in a cell, cleaning up waste and debris. Similarly, the nucleus acts as the brain of the cell, overseeing and regulating cellular activities and containing the genetic material necessary for cell function.
