How do you think the structure of a cell membrane might influence the way molecules move in and out of a cell?

Multiple Choice

Why is the structure of the cell membrane important for maintaining homeostasis in living organisms?

• It allows selective movement of substances in and out of the cell

• It provides energy to the cell

• It stores genetic information

• It helps the cell divide

Multiple Choice

Which of the following is NOT a part of the cell theory?

• All living things are made of cells.

• Cells are the basic unit of life.

• All cells come from other cells.

• Cells can exist without living things.

Multiple Select

Which statements about unicellular and multicellular organisms are correct?

• Unicellular organisms are composed of one cell.

• Multicellular organisms are composed of many cells.

• Multicellular organisms can organize into tissues, organs, and organ systems.

• Unicellular organisms have organ systems.

Fill in the Blank

The smallest part of an organism that is still capable of all of life’s processes is the ___.

Open Ended

Explain the main differences between prokaryotic and eukaryotic cells.

Multiple Select

Which structures are found in all cells?

• Genetic material (DNA or RNA)

• Cytoplasm

• Cell membrane

• Mitochondria

Multiple Choice

What is the main function of the phospholipid bilayer in the cell membrane?

• To provide energy for the cell

• To control what enters and leaves the cell

• To store genetic information

• To produce proteins

Open Ended

Explain how the phospholipid bilayer contributes to the selective permeability of the cell membrane.

Fill in the Blank

Why is the cell membrane referred to as the 'Fluid Mosaic Model'?

Multiple Choice

Which of the following best describes the function of proteins embedded in the cell (plasma) membrane?

• They provide energy for the cell.

• They are embedded for transport.

• They store genetic information.

• They produce carbohydrates.

Multiple Choice

Which of the following organelles are present in both plant and animal cells?

• Chloroplasts, Mitochondria, Nucleus, Cell Wall

• Mitochondria, Nucleus, Ribosomes, Golgi Apparatus

• Vacuole, Chloroplasts, Cell Wall, Lysosome

• Cell Wall, Ribosomes, Chloroplasts, Nucleus

Open Ended

Compare and contrast the structure and function of animal and plant cells based on the diagrams provided.

Fill in the Blank

The main difference between prokaryotic and eukaryotic cells is the presence of a ___ in eukaryotic cells.

Open Ended

Reflecting on today's lesson, what questions do you still have about how molecules move through a cell membrane or how the membrane maintains homeostasis?

Multiple Choice

Which of the following best describes how the structure of a cell's membrane contributes to maintaining homeostasis?

• It allows selective movement of substances in and out of the cell.

• It provides energy for cellular processes.

• It stores genetic information.

• It produces proteins for the cell.
