• A plant having thousands of root hairs is helpful because it is creating a large surface area which means it would absorb more water
• Plant roots cant absorb mineral ions by diffusion since absorbtion of minerals is not a passive process and needs energy
• Plants absorb minerals by osmosis
• Respiration is the process inside cells that produce carbon dioxide
• During respiration the ribcage goes up because of the muscles between the ribcage
• Osmosis is the movement of water molecules from a region of high water concentration to a region of low water concentration
• When a solution is hypertonic the specimen shrinks
• Hypotonic solutions have a higher concentration on the inside
• Tar slowly kills lungs. Anything that dies turns black
