What is a prokaryotic cell?

Back

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

Front

What are the main parts of a prokaryotic cell?

Back

The main parts include the cell membrane, cytoplasm, ribosomes, and genetic material (DNA), but they do not have a nuclear membrane.

Front

What is the function of the rough endoplasmic reticulum (rough ER)?

Back

The rough ER is involved in the production and folding of proteins, which are essential for various cellular functions.

Front

What is the nucleus of a cell?

Back

The nucleus is the organelle that contains the cell's DNA and acts as the control center, regulating gene expression and cell division.

Front

What are ribosomes and their function?

Back

Ribosomes are cellular structures that synthesize proteins by translating messenger RNA (mRNA) into polypeptide chains.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and various organelles.

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.

Front

What is the role of mitochondria in a cell?

Back

Mitochondria are known as the powerhouse of the cell, as they produce energy (ATP) through cellular respiration.

Front

What is the function of chloroplasts?

Back

Chloroplasts are organelles found in plant cells that conduct photosynthesis, converting light energy into chemical energy.

Front

What is the cell membrane?

Back

The cell membrane is a protective barrier that surrounds the cell, controlling the movement of substances in and out.
