Grasses have the ability to grow ...

Why are cations difficult to get access to in the soil? - They are difficult because they bond tightly to the soil so another cation has to come break their bond Clay is negatively charged and tightly bind to cations making it difficult to uptake from soil Is the need for CO2 and O2 in leaves the same when compared to roots? - The difference is because of what the plant needs at that certain spot. The CO2 is needed for photosynthesis to make sugar for the plant What are the two key tissues...
