What is a eukaryotic cell?

Back

A eukaryotic cell is a type of cell that has a nucleus and membrane-bound organelles. Its DNA is contained within the nucleus.

What structure is present in eukaryotic cells but not in prokaryotic cells?

Back

The nucleus is present in eukaryotic cells but absent in prokaryotic cells.

Front

What are membrane-bound organelles?

Back

Membrane-bound organelles are specialized structures within a cell that are enclosed by membranes, found only in eukaryotic cells.

Front

What is the function of the nucleus in a eukaryotic cell?

Back

The nucleus houses the cell's DNA and is responsible for regulating gene expression and cell division.

Front

What is the role of the cell wall?

Back

The cell wall provides structural support and protection to the cell, primarily found in prokaryotic cells and plant cells.

Front

How does DNA differ in prokaryotic and eukaryotic cells?

Back

In prokaryotic cells, DNA is free-floating in the cytoplasm; in eukaryotic cells, DNA is enclosed within the nucleus.

Front

What is cytoplasm?

Back

Cytoplasm is the jelly-like substance within a cell that contains organelles and is the site of many cellular processes.

Front

What is the function of the plasma membrane?

Back

The plasma membrane regulates the movement of substances in and out of the cell and provides protection.

What are examples of membrane-bound organelles?

Back

Examples include the endoplasmic reticulum, Golgi apparatus, mitochondria, and lysosomes.
