Unit 2 Review - Cells

Front

What is the hydrophobic region of the cell membrane?

Back

The hydrophobic region of the cell membrane consists of the fatty acid tails of phospholipids, which repel water.

Front

What is passive transport?

Back

Passive transport is the movement of particles across a cell membrane from an area of high concentration to an area of low concentration without the use of energy.

Front

What process allows water to move into plant root cells when the concentration of water is higher in the soil?

Back

Osmosis allows water to move into plant root cells.

Front

What are the two main types of cells?

Back

The two main types of cells are Prokaryotes and Eukaryotes.

Front

How do prokaryotic and eukaryotic cells differ?

Back

Eukaryotic cells have a nucleus, while prokaryotic cells do not.

Front

What type of cell is characterized by the presence of membrane-bound organelles?

Back

Eukaryotic cells are characterized by the presence of membrane-bound organelles.

Front

What is the function of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, providing protection and support.

Front

What is osmosis?

Back

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

Front

What is the role of the nucleus in eukaryotic cells?

Back

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

Front

What are the main components of the cell membrane?

Back

The main components of the cell membrane are phospholipids, proteins, cholesterol, and carbohydrates.
