Cell Structure and Function

Front

What does the Fluid Mosaic Model describe?

Back

The Fluid Mosaic Model describes the cell membrane as made of many different parts that are not fixed in one place.

Front

What is a hypertonic solution?

Back

A hypertonic solution is one where the concentration of a solution outside the cell is higher than the concentration inside the cell.

Front

True or False: Prokaryotes contain cytoplasm.

Back

True.

Front

How do water, oxygen, and carbon dioxide move across the permeable cell membrane?

Back

They move by diffusion.

Front

What type of organisms are prokaryotes?

Back

Prokaryotes are unicellular organisms.

Front

What is the primary function of the cell membrane?

Back

The primary function of the cell membrane is to protect the cell and regulate what enters and exits.

Front

What are the main components of the cell membrane according to the Fluid Mosaic Model?

Back

The main components are phospholipids, proteins, cholesterol, and carbohydrates.

Front

What is osmosis?

Back

Osmosis is the diffusion of water across a selectively permeable membrane.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells do not have a nucleus or membrane-bound organelles, while eukaryotic cells do.

Front

What role do proteins play in the cell membrane?

Back

Proteins in the cell membrane assist in transport, act as receptors, and provide structural support.
