Exploring Cell Structure and Function in AP Biology

What is the main focus of Unit 2 in this AP Biology review session?

• Genetic inheritance

• Photosynthesis

• Cell structure and function

• Enzyme structure and function

Which organelle is known as the powerhouse of the cell?

• Nucleus

• Golgi apparatus

• Mitochondria

• Lysosome

What is the primary function of the Golgi apparatus?

• Breaking down waste

• Synthesizing lipids

• Generating ATP

• Packaging and transporting proteins

What type of molecules can pass through the plasma membrane via simple diffusion?

• Ions

• Proteins

• Small nonpolar molecules

• Large polar molecules

Which transport mechanism requires energy to move molecules against their concentration gradient?

• Active transport

• Simple diffusion

• Facilitated diffusion

• Osmosis

What is the primary function of exocytosis in cellular transport?

• To bring materials into the cell

• To divide the cell into two

• To release materials from the cell

• To create new organelles

Which organelle is primarily responsible for producing vesicles for exocytosis?

• Lysosome

• Nucleus

• Golgi apparatus

• Mitochondria

In a hypertonic solution, what happens to the water inside a cell?

• Water moves into the cell

• Water moves out of the cell

• Water remains static

• Water is converted into solute

Why do plant cells not burst in a hypotonic environment?

• They have a rigid plasma membrane

• They do not absorb water

• They have a contractile vacuole

• They have a cell wall

Why is a high surface area to volume ratio important for cells?

• It allows for more efficient energy exchange

• It reduces the need for a plasma membrane

• It makes the cell more rigid

• It increases the cell's volume
