Word equation for Photosynthesis	Carbon Dioxide+Water->Glucose+Oxygen 6CO2+6H2O->C6H12O6+6O2
Why do multicellular organisms require complex transport system for gas exchange, but single celled organisms do not?	-The surface area to volume ratio is bigger for the single celled organism , compared to the multi-cellular organism. -Diffusion would not be efficient enough due to the thickness in a multicellular organism.
What is the Xylem made out of?	Lignin
What do the Xylem cells transport and what to/where from?	They transport water and minerals up to the stem from the roots to the shoots and leaves. This transport occurs in only one direction.
