• All cells have the same structure and function.

• Cells arise from pre-existing cells.

• Only plants are made up of cells.

Which of the following is a key difference between plant cells and animal cells.

• Plant cells have chloroplasts, while animal cells do not. 

• Both plant and animal cells have a cell wall, but only plant cells have mitochondria. 

• Animal cells have a large vacuole, while plant cells do not. 

• Plant and animal cells both lack a nucleus. 

What is the primary function of cytoplasm in a cell.

• To store genetic information.

• To transport nutrients and waste products.

• To support and suspend organelles, and provide a medium for chemical reactions. 

• To protect the cell from damage. 

According to the cell theory, where do cells originate from?

• Cells come from spontaneous generation.

• Cells come from preexisting cells.

• Cells are created from the atmosphere.

• Cells are formed through chemical reactions in the nucleus.

Which of the following is one way that cells maintain homeostasis?

• By absorbing heat from the environment to regulate temperature.

• By relying on external sources of energy to maintain balance.

• By extracting energy from food and using it to power functions in cells.
