19. The areas between the location of leaf attachments on the stem are called ___?
vascular bundles

photo respiration occurs usually in times of drought. limited water forces the plant to close stomata - therefore blocking co2. with lo concentrations of co2 and high concentrations of 02 - the enzyme rubisco starts to bind 02 instead of co2. this pr
20. Why do most roots tend to die in soils that contain very high concentrations of salts (or fertilizer)?
If there is a higher concentration of salts outside of the root - then water will not move inside the roots against the concentration gradient. the roots will dehydrate and eventually die
