The cell membrane is an important factor for the cell to maintain homeostasis. This is due to its specific function the cell membrane does. Describe the function of the cell membrane.
A. The main function of the cell membrane is to make proteins.
B. The main function of the cell membrane is to provide structure to the cell by using microtubules, actin filaments, and intermediate filaments.
C. The main function of the cell membrane is to store the DNA and protect it.
D. The main function of the cell membrane is to regulate the movement of substances in and out of the cell. Either through active transport or passive transport.
Name one type of facilitated diffusions that cells.
A. Exocytosis
B. Channel-mediated diffusion
C. Osmosis
D. Endocytosis
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
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
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
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.
A cell needs to intake substances to maintain function. This commonly known as endocytosis. There are three types of endocytosis, what are they?
A. mediated endocytosis, osmosis, and pinocytosis.
B. mediated endocytosis, phagocytosis, and potassium pump
C. phagocytosis, pinocytosis, and mediated endocytosis
D. pinocytosis, mediated endocytosis, and protein synthesis
What type of carbohydrate is in this image.
A. Strach
B. Glycoprotein
C. Cellulso
D. Glycolipid
A plant cell with a sucrose concentration of .9 M of sucrose is put into an extracellular fluid with a sucrose concentration of .4 M. What is the tonicity of the solution to the cell?
A. Hypertonic
B. Isotonic
C. Hypotonic
A cell is removing large amounts of substances out of the cell through a transport vesicle. It uses energy for it. What type of transport is this?
A. Exocytosis
B. Osmosis
C. Endocytosis
D. 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
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.
