Front

What are eukaryotes?

Back

Eukaryotes are organisms whose cells contain a nucleus enclosed within membranes, unlike prokaryotes, which do not have a nucleus.

Front

What is a significant disadvantage of electron microscopes?

Back

Cells die when prepared for viewing, which limits the observation of live cells.

Front

What structures are found in plant cells?

Back

Plant cells typically contain a cell wall, chloroplasts, a large central vacuole, mitochondria, ribosomes, and a nucleus.

Front

What is the function of the cytoskeleton?

Back

The cytoskeleton provides a framework and anchor for organelles within the cell, helping maintain its shape.

Front

What is an organ system?

Back

An organ system is a group of organs that work together to perform a specific function in an organism.

Front

What distinguishes prokaryotic cells from eukaryotic cells?

Back

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

Front

What is the role of mitochondria in a cell?

Back

Mitochondria are known as the powerhouse of the cell, as they generate ATP through cellular respiration.

Front

What is the function of ribosomes?

Back

Ribosomes are responsible for protein synthesis in the cell.

Front

What is the cell wall?

Back

The cell wall is a rigid outer layer that provides support and protection to plant cells.

Front

What is the difference between scanning and transmission electron microscopes?

Back

Scanning electron microscopes provide 3D images of surfaces, while transmission electron microscopes provide detailed images of internal structures.
