Open Ended

Why are we learning about cell structure...AGAIN?

Match

Match the following

• ribosomes

• plasma membrane

• mitochondria

• vacuoles

• nucleolus

site of protein synthesis

regulates the materials that enter/exit

food--> usable energy fro the cell

structures that store food, water, waste

site of ribosome synthesis

• site of protein synthesis

• regulates the materials that enter/exit

• food--> usable energy fro the cell

• structures that store food, water, waste

• site of ribosome synthesis

Open Ended

Regarding the plasma membrane, what areas of human anatomy and physiology do you think this would be important to understand?

Multiple Choice

If you were stranded on an island in the middle of the ocean, would it be a good idea to drink the seawater?

• No, your cells would be saltier than the seawater, so water would leave the cells.

• 
  No, your cells would be less salty than the seawater, so water would leave the cells.

• 
  Yes, your cells would be less salty than the seawater, so water would move into your cells.

• Yes, your cells would be saltier than the seawater, so water would move into the cells.

Multiple Select

Which of the following statements about the nucleus, DNA, and protein synthesis are true?

• 
  Genes are segments of DNA that carry instructions to make a protein.

• The nucleus of a cell is responsible for packaging proteins made by the ribosomes.

• Genes are located in the ribosomes in eukaryotic cells.

• Ribosomes synthesize proteins using instructions that come from the DNA stored in the nucleus.

Plasma membrane-Red

Nucleus- Green

Cytoplasm- Yellow

Multiple Choice

Certain traits, such as eye color, are the result of proteins produced by the body. Which of the structures listed below stores the instructions for making proteins?

• DNA

• smooth endoplasmic reticulum

• mitochondria

• vacuoles

Summary

Today, you learned:

• the presence of a nucleus and other membrane-bound organelles defines a cell as eukaryotic;

• the organelles perform specific tasks to support the cell;

• water will move across the plasma membrane from a less salty environment to a saltier environment; and

• DNA plays a role in producing physical traits.
