Concept explainers
To explain: The similarities between mycorrhizae and root nodules.
Introduction: The underground branching root systems are often more extensive than the areal part of the plant. The extension of root depth and spread of a plant differ from that of another plant species, and they also vary among individuals of the same species. The dissolved minerals are transported from roots to the leaves throughout the plant in the xylem.
To explain: The way in which mycorrhizae differ from root nodules.

- How do mycorrhizae improve the growth of trees?In what way(s) are the root nodule and mycorrhizalsymbioses similar? In what major way do they differ?arrow_forwardHow do mycorrhizal fungi promote plant diversity?arrow_forwardWhich of the following is not a way in which antifungaldrugs are effective?(a) They interfere with nucleic acid synthesis.(b) They increase plasma membrane permeability causingexcessive leakiness of essential substances.(c) They can impair the mitotic spindle apparatus.(d) They can induce mycorrhizae production.(e) None of the abovearrow_forward
- A 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_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_forwardIn mycorrhizal associations with plants what are the structures produced by VAM fungi and Ectomycorrhizal fungi to facilitate the exchange of nutrients, and how do they differ?arrow_forward
- Mycorrhizae 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_forwardWhat are some of the main differences between the cellwalls of plants and those of bacteria?arrow_forwardBiologists have discovered that many mycorrhizal fungi are sensitive to a low pH. What human-caused environmental problem may prove catastrophic for these fungi? How may this problem affect their plant partners? What measures could we take to decrease the problem?arrow_forward
- What are lenticels? What is its taxonomic significance?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_forwardFungal reproduction: Provide name of structures in photo A and B and describe if the structure is involved in asexual or sexual reproduction Photo A below Photo B below 667 umarrow_forward
