internode
vascular bundles
water molecules are split - through the energy of light - into hydrogen ions - electrons - and oxygen
stele
23. Differentiate between diffusion and osmosis?
mychorizea
diffusion is the movement of particles from high to low concentration; osmosis is movement of water from high to low concentration
diffuse out
callyx/corolla
24. Actively dividing cells can be found in ___?
eristems
root hairs
exocarp
fibrous
25. Why is an Irish/white potato classified as a modified stem?
ovary
it has node marks all over it where branches could grow off of.
mycoorhizae

rain
anther
plasmolysis
cellulose
27. When humidity is low - ____ ?
