The association is known as _________. a. root nodule c. root hair b. mycorrhiza d. hyphaThe Flemish physician/plant physiologist Jan Baptista van Helmont was the first to publish his claim that the growth of plants (like willow trees) requires nutrition from which environmental source? water (a hydrogen-containing source which we now designate as H2O) sucrose (a carbon-containing source which we now designate as C12H22O11) ammonia (a nitrogen-containing source which we now designate as NH3) glucose (an oxygen-containing source which we now designate as C6H12O6) methane (a carbon-containing source which we now designate as CH4)Compare and contrast the acquisition and transport of water and nutrients in plants with the acquisition and transport of nutrients in humans. kind of in detail if possible.

- Which of the following explains why pea plants in high soil nitrogen conditions have so few rhizobial nodules on their roots? When there is already high soil nitrogen there is a very large cost to having rhizobial nodules. The rhizobia bacteria in the nodules fix nitrogen when there isn't enough in the soil, so when there is already high soil nitrogen there is no advantage for the pea plant to expend the extra energy housing the rhizobia. The rhizobia bacteria in the nodules use nitrogen when there isn't enough in the soil, so in conditions of high soil nitrogen the plant tries to exclude the rhizobia to keep the nitrogen for itself. When there is already high soil nitrogen there is no benefit to the plant to having rhizobial nodules, which can rob the plant of the high nitrogen supplies so that the rhizobia bacteria do not have to fix the nitrogen themselves.The two pictures below are two soil profiles that typically form in under different types of vegetation, but can also occur relatively close together: 20 40 First, using morphological clues learned in lab, define what these two soil orders are. Be sure to indicate which soil is which (e.g., "the soil of the left is."). Then describe which CIORPT factor and which soil forming.process is probably most important in determining the difference between these two soil types are fairly close to one another?What are ways in which plants accomplish tissue-level transport?a. transmembrane transport of solutes from one cell to anotherb. symplastic transport of materials from one cell to another viaplasmodesmatac. apoplastic transport of water and dissolved solutes through cell wallsand intercellular spacesd. All of the above are used for tissue-level transport.e. None of the above are used for tissue-level transport.
