Biology EOC 2020 Review

Which cell structure is correctly paired with its primary function?

• ribosome - movement
• mitochondrion - energy production
• vacuole - cell division
• nucleus - storage of nutrients

Which macromolecule is shown?

• lipid
• protein
• nucleic acid
• carbohydrate

What is the function of carbohydrates?

• store genetic information
• store energy (long-term)
• store energy (short-term)
• build skin, hair, nails, muscles

Carbohydrates are made of... 

• C H O
• C H O N
• C H O N P
• C H O N S

Which organelle uses energy from sunlight to make sugar?

• mitochondria
• nucleus
• chloroplasts
• vacuoles

I make proteins for the cell! What am I?

• mitochondria
• nucleus
• ribosome
• chloroplast

Which word is NOT correctly paired to its definition?

• homeostasis - balance between sides
• equilibrium - equal on both sides
• passive transport - does not use energy
• active transport - flows from high to low

What is the definition of  Selective Permeability?

• The movement of materials across the cell membrane that requires NO ENERGY from the cell.
  
• The movement of materials through (or across) the cell membrane
  
• The ability of the cell membrane to allow some things to pass through while preventing other things from passing through.
• The movement of molecules from an area of high concentration to a area of low concentration 
  

The diffusion of water through a semi-permeable membrane is called?

• Osmosis
• Cell wall
• Diffusion
• Respiration

Which is a correct scenario for osmosis?

• In a hypotonic solution, there is more solute on the inside so water moves out.
• In a hypotonic solution, there is more solute on the outside so water moves out.
• In a hypertonic solution, there is more solute on the outside so water moves out.
• In a hypertonic solution, there is more solute on the inside, so water moves in.
