Preview:


A cell enters a sucrose solution with a concentration of .10 M. The cell’s sucrose concentration is .5 M. What type of tonicity is the cell compared to the solution?

A. Hypotonc

B. Hypertonic

C. Isotonic


Scientists think it due to it energy making organelle not functioning properly. What will happen if the cell is not able to create the energy overtime?

A. The cell will die due to the cell’s lack of macromolecules since they need energy to be transported into the cell.

B. The cell will not be affected in the rate molecules needed in the cell without energy.

C. The cell will have a increased rate of molecules needed in the cell without energ.

D. The cell will prosper under this condition.


Name one type of facilitated diffusions that cells.

A. Exocytosis

B. Channel-mediated diffusion

C. Osmosis

D. Endocytosis



What type of carbohydrate is in this image.

A. Strach

B. Glycoprotein

C. Cellulso

D. Glycolipid


A cell is engulfing large amounts of substances through vesicles. It uses energy for it can transport it. What type of transport is this.

A. Osmosis

B. Pinocytosis

C. Endocytosis

D. Exocytosis


Hole like structures in the cell wall filled with cytosol that connect adjacent cells & allows communication between cells.

A. phospholipids

B. plasmodesmata

C. protein pumps

D. protein channels


The cell is seen having trouble with cell to cell recognition . Scientists think it may be due to a part of the cell membrane not properly functioning. What part of the cell membrane is not working correctly.

A. integral proteins

B. carbohydrates

C. plasmodesmata

D. Peripheral proteins



The picture shows a solution of sugar and water in a beaker. The barrier acts like a semiperamable membrane. The semipermeable membrane only allows water to pass through and not sugar. Which side of the beaker will the water move into.

A. The left side

B. The right side



Scientist drop sugar into a water solution. Overtime the sugar diffuse in the evenly in the water solution. Why did this happen and what type of transport is this?

A. This happens because when sugar molecules are in low concentration they move into a high concentration. This is an example of active transport.

B. This happens because when sugar molecules are in low concentration they move into a high concentration. This is an example of passive transport.

C. This happens because when sugar molecules are in a high concentration they move into a low concentration. This is an example of active transport.

D. This happens because when sugar molecules are in a high concentration they move into a low concentration. This is an example of passive transport.


The cell membrane is often called a mosaic model. What are the reasons they call it this?

A. The cell membrane is composed of many things.

B. It looks like a painting

C. The cell membrane is made up of few things

D. The cell membrane is shaped like a donut


The cell membrane is composed of many substances but also able to maintain its fluidity . Due to this characteristic it is commonly known as the fluid mosaic model. Identify 3 things the cell membrane is composed of.

A. phospholipids, Glycolipids and cellulose

B. Carbohydrates, nucleic acids and proteins

C. Carbohydrates, cholesterol, and proteins

D. Cholesterol, proteins, and mRNA


What is called when a cell has an even amount of water movement in and out of the cell.

A. hypertonic

B. isotonic

C. hypotonic


A cell membrane is usually able to maintain fluidity even in cold temperature. Scientists found an animal cell that becomes solid when they expose it to cold temperatures. Identify what part of the cell membrane is not properly working in the animal cell.

A. Intergral proteins

B. Cholesterol

C. Carbohydrates

D. Steriods

A. Hypertonic

B. Isotonic

C. Hypotonic


A cell is trying to move in a charged large molecule through the cell. What type of transport is needed to transport the molecule into the cell?

A. Passive transport

B. Active transport
