What are Eukaryotic cells?

Back

Eukaryotic cells are complex cells that contain a nucleus and membrane-bound organelles. Examples include animal cells, plant cells, and fungi.

Front

What are Prokaryotic cells?

Back

Prokaryotic cells are simpler cells that do not have a nucleus or membrane-bound organelles. They typically have circular DNA. An example is bacteria.

Front

What is the function of mitochondria?

Back

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

Front

What is the role of peroxisomes in liver cells?

Back

Peroxisomes are organelles that contain enzymes for breaking down fatty acids and detoxifying harmful substances, which is crucial for liver function.

Front

What is the structure of DNA in prokaryotic cells?

Back

Prokaryotic cells typically have circular DNA, which is not enclosed within a nucleus.

Front

What distinguishes eukaryotic cells from prokaryotic cells?

Back

Eukaryotic cells have a nucleus and membrane-bound organelles, while prokaryotic cells do not.

Front

What is the primary function of the nucleus in eukaryotic cells?

Back

The nucleus houses the cell's genetic material (DNA) and controls cellular activities by regulating gene expression.

Front

What are membrane-bound organelles?

Back

Membrane-bound organelles are specialized structures within eukaryotic cells, such as the nucleus, mitochondria, and endoplasmic reticulum, that perform specific functions.

Front

What is the significance of chloroplasts?

Back

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

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.
