Unit 2 - Cells Honors

Front

What is the part of an experiment that is being measured?

Back

dependent variable

Front

What is the process of transporting water across a semipermeable membrane called?

Back

osmosis

Front

If a cell is 70% water and 30% solute, and it is placed in a solution that is 75% water and 25% solute, what type of solution is it in?

Back

hypotonic because water is entering the cell

Front

If a cell is 80% water and 20% solute, and it is placed in a solution that is 60% water and 40% solute, what type of solution is it in?

Back

hypertonic because water is exiting the cell

Front

What does cell theory state about primitive cells like prokaryotes?

Back

Even primitive cells, like the prokaryote, can carry out the functions of life.

Front

What is the definition of a cell?

Back

The basic unit of life that can carry out all life processes.

Front

What is the difference between a hypotonic and hypertonic solution?

Back

A hypotonic solution has a lower concentration of solute compared to the cell, causing water to enter the cell; a hypertonic solution has a higher concentration of solute compared to the cell, causing water to exit the cell.

Front

What is the role of the cell membrane?

Back

To regulate what enters and exits the cell, maintaining homeostasis.

Front

What is osmosis?

Back

The diffusion of water across a selectively permeable membrane.

Front

What is a solute?

Back

A substance that is dissolved in a solution.
