Students were asked to determine if the two slides are cells taken from plants or cells taken from animals. Which of the students’ explanations is most accurate?

• Student 1: Slides 1 and 2 are both animal cells because they both have a nucleus.

  
  

• Student 2: Slides 1 and 2 are both plant cells because they both have cell membranes.

  
  

• Student 3: Slide 1 is an animal cell because it does not have a cell wall. Slide 2 is a plant cell because it does have a cell wall.

  
  

• Student 4: Slide 1 is a plant cell because it does not have chloroplasts. Slide 2 is an animal cell because it does have chloroplasts
