- How is the mycorrhizal association helpful in absorption of water and minerals in plants?arrow_forwardIn a practice known as crop rotation, farmers alternate a crop of legumes (plants like beans, whose roots bear nodules containing Rhizobium) with a crop of non- legumes. What is the benefit of this practice?arrow_forwardA group of researchers run an experiment to determine the effect of mycorrhizae (a fungus) on plant growth. The researchers set up three experimental groups: A large amount of mycorrhizae is applied to the plants in group 1 a smaller amount of mycorrhizae is applied to the plants in group 2, and no mycorrhizae is applied to the plants in group 3. Which group(s) is/are the experimental group(s)? More than one answer may be correct. Select all that apply. O Group 3 Group 2 Group 1arrow_forward
- The roots of legumes, such as peas and beans, have special nodules that are home to large numbers of bacteria. What benefit do these bacteria provide to the plant? What do they receive in exchange?arrow_forwardWhich of the following statements are true of the stomata on the leaves of vascular plants? A) They regulate intake of carbon dioxide needed for photosynthesis.B) They regulate release of oxygen to the air.C) They regulate loss of water.D) They are able to open or close depending on environmental conditions.E) They regulate the absorption of light by chlorophyll.arrow_forwardThe greatest difference in health between two groups of plantsof the same species, one group with mycorrhizae and one groupwithout mycorrhizae, would be in an environment(A) where nitrogen-fixing bacteria are abundant.(B) that has soil with poor drainage.(C) that has hot summers and cold winters.(D) in which the soil is relatively deficient in mineral nutrientsarrow_forward
- What is false about the image below? A) The cells are part of plant ground tissue B) The cells are parenchyma cells. C) The cells provide flexible support. D) The cells would be a site of starch storage if they were in the roots 373arrow_forwardMycorrhizae enhance plant nutrition mainly by(A) absorbing water and minerals through the fungal hyphae.(B) providing sugar to root cells, which have no chloroplasts.(C) converting atmospheric nitrogen to ammonia.(D) enabling the roots to parasitize neighboring plantsarrow_forwardWhich 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.arrow_forward
