Summary Introduction
To review: The importance of hydrogen bonding in water molecules for the movement of xylem sap in plants.
Concept introduction: Hydrogen bonds exist in water as the hydrogen atoms in one water molecule are attracted towards the oxygen atom of the adjacent water molecule. There is a property of cohesion in water which allows the column of water to be pulled up because molecules of water evaporate at the surface of leaf cells. This process is termed as the cohesion theory of ascent of sap in plants.

- How does acid rain lead to a reduction in the amount of plant nutrients available in soil? O Cation exchange leads to covalent bonding of nutrients on soil particles, making them unavailable to plants. O Nutrient cations (like K*, Ca++ etc) bind in place of protons released by soil particles, making the nutrients unavailable and the soil water more acidic. O Cations exchange places with anions during cation exchange, which confuses roots and turns LATS into HATS, after which the endodermis generates a caspian endothelium O During acid rain nutrients leach away after cation exchange takes placearrow_forwardDescribe the cohesion-tension model of water movement through xylem.

- But how are the two types of mesophyll involved? From what I understand, CO2 enters the stomata, and then the citric acid cycle of the mitochondia in the mesophyll use the carbon atoms do produce glucose, which then goes through phloem loading and it either used or stored. My question, I guess, is how exactly are the two types of mesophyll involved? Is only one used or are both used at different times in the production of the glucose?arrow_forward(a) What is the shape and arrangement of the palisade mesophyll in the dicot leaf?
