Quiz 4 Flashcards
Explain the process of water moving from roots to the leaves
The cohesion-tension theory is when water is pulled up by transpiration, which creates a negative pressure in the plant. Water’s cohesive properties allow for a constant flow of water that travels up the stem, and into the leaves (capillary action).
Give and explain two ways plants use to increase nutrient uptake
Mycorrhizae - symbiotic relationship between fungi and roots that increases the surface area
Root nodules - nitrifying bacteria that lives on the roots that grabs nitrogen out of the air and puts it into the plant (peanut plants)
