Cell Structure Function Cases: Club Case

A simplified cell key: membrane—regulates exchange; nucleus—contains much genetic information; mitochondria—help release usable energy; chloroplasts—use light in photosynthesis in plant cells. The focus job is helping release usable energy from fuel molecules. Structures have different roles; this model does not show every cell type.

Use the supplied scenario and model. Show calculations or explain the evidence requested in each task.

Use a Particle Model With Care

A simplified particle model

In a solid model, particles remain near relatively fixed positions while vibrating. In a liquid model, nearby particles can move past one another. In a gas model, particles are more widely separated and move through the available space. Particle pictures are not actual-scale photographs.

Use the material to work through each task. Show the requested response.
