What are prokaryotic cells?

Back

Prokaryotic cells are simple, unicellular organisms that lack a nucleus and membrane-bound organelles. Examples include bacteria and archaea.

Front

What are eukaryotic cells?

Back

Eukaryotic cells are complex cells that contain a nucleus and membrane-bound organelles. They can be unicellular or multicellular, such as plants, animals, and fungi.

What is the main difference between prokaryotic and eukaryotic cells?

Back

The main difference is that prokaryotic cells do not have a nucleus or membrane-bound organelles, while eukaryotic cells do.

Front

What is a nucleus?

Back

A nucleus is a membrane-bound organelle that contains the cell's genetic material (DNA) and controls cellular activities.

Front

What are membrane-bound organelles?

Back

Membrane-bound organelles are specialized structures within a cell that are enclosed by membranes, such as the nucleus, mitochondria, and endoplasmic reticulum.

Front

What is the function of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, providing protection and structural support.

Front

What is the genetic material in prokaryotic cells?

Back

In prokaryotic cells, the genetic material is typically a single circular DNA molecule located in the nucleoid region.

Front

What is the genetic material in eukaryotic cells?

Back

In eukaryotic cells, the genetic material is organized into multiple linear chromosomes contained within the nucleus.

Front

What is the role of ribosomes in cells?

Back

Ribosomes are the sites of protein synthesis in both prokaryotic and eukaryotic cells.

Front

What is a flagellum?

Back

A flagellum is a long, whip-like structure that helps some cells, including prokaryotes, to move.
