Part b: observing rhizobium with a hand lens (score for question 2: of 5 points) 2. sketch the inside of the bean nodule, and describe or label what you observed with the hand lens. type your answer here. part c: observing rhizobium with a microscope (score for question 3: of 5 points) 3. sketch the bean nodule, labeling cells with and without rhizobium, showing what you observed with the microscope. type your answer here. conclusions (score for question 4: of 2 points) 4. two new species of plants were introduced into an area that was low in available nitrogen compounds in the soil. one formed nodules and one did not. which species would you reasonably expect to grow more robustly? explain. type your answer here. (score for question 5: of 2 points) 5. how does the location of the nodules relate to the function of the nodule? explain. type your answer here. (score for question 6: of 2 points) 6. this diagram shows two groups of plant cells, one with rhizobium and one without the bacteria. label which is which, and explain the obvious size difference, using observations from part c of the lab in your answer. type your answer here.
