Unit 1: Cell Structures Test Practice

Front

What is the primary function of carbohydrates in living organisms?

Back

Carbohydrates provide quick energy.

Front

What materials are needed to view plant cells under a microscope?

Back

Microscope, microscope slide, water, and a cover slip.

Front

What type of cell is characterized by the absence of a nuclear membrane?

Back

Prokaryotic cell.

Front

What type of cell has DNA surrounded by a nuclear membrane?

Back

Eukaryotic cell.

Front

In a Venn Diagram comparing carbohydrates and lipids, what function do they share?

Back

Both carbohydrates and lipids provide energy.

Front

What are the two main types of cells in biology?

Back

Prokaryotic and Eukaryotic cells.

Front

What is the role of lipids in biological systems?

Back

Lipids serve as long-term energy storage and are important for cell membrane structure.

Front

What is the difference between prokaryotic and eukaryotic cells in terms of DNA organization?

Back

Prokaryotic cells have circular DNA that is not enclosed in a nucleus, while eukaryotic cells have linear DNA enclosed within a nuclear membrane.

Front

What is a common method for preparing a slide to view cells under a microscope?

Back

Place a drop of water on a microscope slide, add the specimen, and cover it with a cover slip.

Front

What is the significance of the nuclear membrane in eukaryotic cells?

Back

The nuclear membrane protects the DNA and regulates the exchange of materials between the nucleus and the cytoplasm.
