Unit 2 Cell Structure

When looking under a microscope, the image always appears...

• The same as in real life, only larger

• Upside down

• Backwards

• Upside down and backwards

Which organelle is correctly matched? 

• Mitochondria- makes sugar in a process called photosynthesis

• Cell wall- maintains homeostasis by letting things in and out of the cell

• Nucleus- controls the cell activities

• Golgi Complex- folds proteins

• Shrink

• Stay the same size

Which of the following is true about the cell pictured below? 

• This is an example of passive transport because no energy is required.

• This is an example of exocytosis and energy is required.

• This is an example of active transport because the particles are moving from low to high concentration.

• This is an example of endocytosis and energy is required. 

Which of the following is true of prokaryotic cells?
