Prokaryotic and eukaryotic cells

Front

What is a prokaryotic cell?

Back

A prokaryotic cell is a simple, unicellular organism that lacks a nucleus and membrane-bound organelles. Examples include bacteria and archaea.

Front

What is a eukaryotic cell?

Back

A eukaryotic cell is a complex cell that contains a nucleus and membrane-bound organelles. Examples include plant and animal cells.

Front

What is the function of mitochondria?

Back

Mitochondria are known as the powerhouse of the cell, responsible for producing energy (ATP) through cellular respiration.

Front

What is the function of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell, providing protection and structural support.

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 role of flagella in cells?

Back

Flagella are long, whip-like structures that help propel the cell through liquid environments.

Front

How do prokaryotic and eukaryotic cells differ in size?

Back

Prokaryotic cells are generally smaller (0.1 to 5.0 micrometers) compared to eukaryotic cells (10 to 100 micrometers).

Front

What is a cell wall?

Back

A cell wall is a rigid outer layer that provides support and protection to certain cells, such as plant cells and bacteria.

Front

What is the nucleus?

Back

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

Front

What is cytoplasm?

Back

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