Mrs Van Unit1 Lesson 2. Cell structure and function

Study the photograph. Which of the following describes these cells? Select as many as apply.

• animal cells

• plant cells

• prokaryotic

• eukaryotic

If a cell’s surface area-to-volume ratio increased from 3:1 to 4:1, what impact would that have on the transport of materials across the cell membrane?

• it would be unchanged

• transport would increase

• transport would decrease

• none of the above

What is the function of the structure marked A in the illustration below?

• process nutrients

• make proteins

• store wastes

• hold genetic information

Based on what you know of the function of the structure labeled A, select the best analogy of its function

• allow system to function properly

• build system structure

• dispose of system wastes

• consume food

Which of these structures surround cells?

• cell wall and nucleus

• cell membrane and cell wall

• cytoplasm and cytoskeleton

• cell membrane and cytoplasm

What two features do eukaryotes have that prokaryotes do not have?

• cell wall and ribosomes

• nucleus and genetic material

• membrane-bound organelles and nucleus

• membrane-bound organelles and genetic material

Under a high-powered microscope, Dan sees a cellular organelle. The organelle has a double membrane, and the inner membrane is folded. Which organelle does Dan see?

• nucleus

• ribosome

• mitochondrion

• endoplasmic reticulum

Eukaryotic cells and prokaryotic cells have some parts in common. Which of these pairs of parts would you find in both types of cells?

• cytoplasm and nucleus

• cell membrane and cytoplasm

• genetic material and membrane-bound organelles

• cell membrane and membrane-bound organelles

Jorge looks through a microscope and observes the structures of cells on a microscope slide. He concludes that the cells he observes are eukaryotic cells. Which of these structures did Jorge most likely observe before making his conclusion?

• nucleus

• cytoplasm

• cell membrane

• genetic material

Cells must perform many of the same types of functions as body systems do. Which of these pairs correctly matches the cell organelle with the body system that performs a similar function?

• lysosome and circulatory system

• cell membrane and skeletal system

• nucleus and nervous system

• Golgi complex and integumentary system
