Question: Look at Figure 2.1 in your textbook.What are the functions of a cytoskeleton?

Answer: It gives a cell shape,support,and strength.

Question: How is a cytoskeleton like your skeleton?

Answer: It provides structure and protects vital organs contained within it.

Question: How is a cytoskeleton like your muscles?

Answer: Because it can contract like muscles which gives the cell shape,strength,and make it divide.

Question: Write the function or the name of each organism.

Answer: Nucleus-Stores and protects the DNA of the Cell.

Question: Write the function or the name of each organism.

Answer: Endoplasmic Reticulum (ER)-Helps in the production of proteins and lipids.

Question: Write the function or the name of each organism.

Answer: Ribosomes-tiny organelles that link amino acids together to form proteins.

Question: Write the function or the name of each organism.

Answer: Golgi Apparatus-changes proteins,puts into packages and carried to other places in the cell.

Question: Write the function or the name of each organism.

Answer: Vesicles-carries certain molecules from place to place within a cell.

Question: Write the function or the name of each organism.

Answer: Mitochondrion-bean shaped organisms that produce chemical energy that is usable by a cell.

Question: Write the function or the name of each organism.

Answer: Vacuole-sacs of fluids that store materials in a cell.

Question: Write the function or the name of each organism.

Answer: Lysosome-organelles that contain enzymes. Protect a cell by attacking incoming bacteria or viruses.

Question: Write the function or the name of each organism.

Answer: Centriole-help form cilia and flagella,structures that help cells to move or to move liquids past a cell.

Question: What role do cell walls play in a plant?

Answer: They protect,support,and shape the plant cell.

Question: What is the difference between a cell wall and a cell membrane?

Answer: The cell wall is the outside lining of the cell that helps hold the cell together. The cell membrane is inside the C.M. and has the quality of being semi-permable so it can allow various substances to go in and out of the cell.

Question: Why are chloroplasts important?

Answer: Because chloroplasts are the powerhouse of the plant cell. They convert solar energy,carbon dioxide,and oxygen to sugar vias photosynthesis.

Question: Which cell part is a maze of folded membranes where proteins and lipids are produced?

Answer: The Endoplasmic Reticulum.

Question: Which cell part converts food into energy that is usable by a cell?

Answer: Mitochondria.
