Textbook Question

Eukaryotic cells differ from prokaryotic cells in that only eukaryotic cells .a. contain DNA;b. have a plasma membrane;c. are considered to be alive;d. have a nucleus;e. are able to evolve

Verified step by step guidance

Identify the key differences between eukaryotic and prokaryotic cells.

Recall that both eukaryotic and prokaryotic cells contain DNA, have a plasma membrane, and are considered to be alive.

Understand that both types of cells are capable of evolution.

Recognize that the presence of a nucleus is a distinguishing feature of eukaryotic cells.

Conclude that the correct answer is the option that highlights the presence of a nucleus in eukaryotic cells.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Eukaryotic Cells

Eukaryotic cells are complex cells that contain a nucleus and membrane-bound organelles. They are typically larger than prokaryotic cells and can be unicellular or multicellular, including organisms such as plants, animals, and fungi. The presence of a nucleus allows for more organized genetic material and regulation of cellular processes.

Prokaryotic Cells

Prokaryotic cells are simpler, smaller cells that lack a nucleus and membrane-bound organelles. They are usually unicellular and include bacteria and archaea. Their genetic material is not enclosed within a membrane, which allows for rapid reproduction and adaptation, but limits the complexity of cellular functions compared to eukaryotic cells.

Nucleus

The nucleus is a membrane-bound organelle found in eukaryotic cells that houses the cell's genetic material (DNA). It plays a crucial role in regulating gene expression and cell division. The presence of a nucleus is a defining feature that distinguishes eukaryotic cells from prokaryotic cells, which do not have this structure.
