A prokaryote is a single-celled organism that lacks a nucleus and membrane-bound organelles, characterized by its simple structure.

Front

What is a eukaryote?

Back

A eukaryote is an organism whose cells contain a nucleus and membrane-bound organelles, which can be unicellular or multicellular.

Front

What is the main difference between prokaryotic and eukaryotic cells?

Back

The main difference is that prokaryotic cells do not have a nucleus, while eukaryotic cells do.

Front

What is the significance of ribosomes in both prokaryotic and eukaryotic cells?

Back

Ribosomes are essential for protein synthesis and are found in both prokaryotic and eukaryotic cells.

Front

What does it mean for a cell to be unicellular?

Back

A unicellular organism consists of a single cell that performs all necessary functions for life.

Front

What is the role of DNA in prokaryotic cells?

Back

In prokaryotic cells, DNA is typically found in a single circular chromosome that floats freely in the cytoplasm.

Front

What is a nuclear membrane?

Back

A nuclear membrane is a double-layered membrane that encloses the nucleus in eukaryotic cells.

Front

What is the size comparison between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells are generally much smaller than eukaryotic cells.

Front

What is a characteristic feature of prokaryotic cells?

Back

Prokaryotic cells often have a cell wall, which provides structure and protection.

Front

What is the function of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell, maintaining homeostasis.
