Q

What are the types of passive transport?

A

Diffusion-movement from an area of higher concentration to an area of lower concentration
Osmosis- diffusion of water molecules only through a membrane
Facilitated diffusion- when molecules pass through a cell membrane using transport proteins

Q

What is the difference between cellular respiration and photosynthesis?

A

. Cellular respiration is a series of chemical reactions that convert energy in food molecules into ATP. Cp: O2+glucos-> CO2, h20, ATP
Photosynthesis is a series of reactions that convert light energy, water, and CO2 into glucose and give off oxygen. P: CO2+H20+sun-> o2, glucose
