AKS1a. Learning Check #1

Refer to the data table in the picture. What additional information would best support an argument that Specimen A is living and Specimen B is not living?

•  Specimen A can move and Specimen B cannot move.

• Specimen A has cells and Specimen B does not have cells.

• Specimen A needs oxygen Specimen B does not need oxygen.

• Specimen A has many parts and Specimen B does not have many parts.

All living things are made up of one or more cells. Although all living things do not move, they all respond to stimuli from their environment. 

Two students engaged in arguments that plant cells exhibit characteristics of life when they respond to stimuli in their environment.  Which student has presented the best argument for a plant cell responding to stimuli in its environment? Refer to the picture to see the student's arguments.

• Only the argument of Student A represents a plant’s response to stimuli in its environment.  

• Only the argument of Student B represents a plant’s response to stimuli in its environment. 

• Neither argument of Student A or Student B represents a plant’s response to stimuli in its environment.  

• Both arguments of Student A and Student B represent a plant’s response to stimuli in its environment.

A scientist is observing a figure under the microscope that appears to be alive, however she is not sure. The scientist observes a membrane, but after closer observation notices that the image is not clear.  What additional observation could she make to ensure that the object that she is observing under the microscope is alive?

• the objects has a wall around the figure to form the basic structure of the object.

• the object has Organelles to ensure that materials are processed in the cell.

• The object splitting into two parts and continues growing

• the object has a center circle that appears to be a nucleus.

Students are in the lab studying some mystery specimen. The students are asked to determine if the specimens are living or not. The students have each made a list of what to look for in the specimens. Look at the lists each student has created to study the specimens.  Which list do you think will most help the group figure out if the specimen is a living thing or not?

• Student A’s list will be most helpful to determine if the specimen is living because it asks about being able to breathe and being made of cells.

• Student B’s list will be most helpful to determine if the specimen is living because it asks about being made of cells and needing energy.

• Students C’s list will be most helpful to determine if the specimen is living because it asks about having a brain and being made of cells.

• All of the lists will be helpful to determine if the specimen is living because they all ask about movement and being made of cells.
