Cell Organelles
This organelle serves as "protection" and regulates molecules that enter and exit the cell
The Cell Membrane
Fill in the blank "A ______ _________ Model"
"A Fluid Mosaic Model"
Many different components make up the cell membrane.
Finish the phrase "Diffusion is..."
The movement of molecules from a high concentration to an area of low concentration.
Finish the phrase "Osmosis is..."
The movement of water molecules from an area of high concentration to an area of low concentration.
What are the 4 major macromolecules?
Carbohydrates, Proteins, Nucleic Acids and Lipids.
Where does protein synthesis occur in the cell?
What is Ribosomes
This molecule helps to stabilize the cell membrane.
Cholesterol
Active Transport
Movement of molecules across the cell membrane with the use of energy.
The same amount of water is flowing in and out of the cell.
Isotonic
Triglycerides
Polymer of a lipid.
The differences between the Plant Cell and Animal Cell
Plant Cells have larger vacuoles, a cell wall and a chloroplast.
The function of membrane protein channels
Allows the passage of molecules and ions in and out the cell through passive transport.
Molecules moving with the concentration gradient requiring no use of energy.
Passive Transport
Hypotonic is...
When the cell swells up due to water moving into the cell.
What components make up the Experimental Design?
Variables, Controls, Control Group, Experimental Group, Hypothesis, Results/Data and Conclusion
My function is to breakdown cellular waste and excess or worn out cell parts. Who am I?
What is lysosomes
What is the cell membrane made of?
The cell membrane is a phospholipid bilayer consisting of non polar fatty acid tails and a polar hydrophobic head.
I'm an ion that needs to move across the cell membrane, but I need help. I will use a transport protein to help me.
Facilitated Diffusion.
The cell shrivels up and becomes smaller.
Hypertonic
The difference between the Experimental Group and Control Group.
Experimental Group= contains the independent variable.
Control Group=used for comparison and does not contain the independent variable.
Energy
Mitochondria
Serves as the site of Cellular Respiration and providing energy.
To increase the effectiveness of membrane mechanics in the cell membrane...
Increase the amount of transport molecules or protein channels to allow more molecules to enter/exit.
Endocytosis vs. Exocytosis
Endocytosis the process of transporting molecules into the cell by engulfing the molecule with its membrane through active transport.
Exocytosis is the process of transporting molecules out of the cell through active transport.
Based on the "Egg Lab" the egg being placed in the vinegar solution is an example of
Hypotonic solution because the egg increased in size.
Why is it easier for our bodies to breakdown glucose and harder to breakdown sucrose?
Glucose is considered a simple sugar which allows our body to break down the molecule easily.
Sucrose is considered a complex sugar. It is more difficult for our body to breakdown because complex sugars have two or more sugars.
