- Many fungal pathogens get food by causing plant cells to become leaky, releasing nutrients into the intercellular spaces. Would it benefit the fungus to kill the host plant in a way that results in all the nutrients leaking out? Explain.arrow_forwardThe nutrition of some plants is enhanced by a mutually beneficial association between a root and a fungus. The association is known as _________. a. root nodule c. root hair b. mycorrhiza d. hyphaarrow_forwardThe waxy layer that covers aerial parts of plants is the (a) cuticle (b) archegonium (c) protonema (d) stoma (e) thallusarrow_forward
- In 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_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_forwardAdvantages of retaining the young sporophyte as an embryo within the parent plant include the following choices:A) The embryo is protected from desiccation.B) The embryo is able to quickly replicate, producing multiple copies that can be widely dispersed.C) The embryo is able to attain nutrients supplied by maternal tissues.D) The embryo is protected from pathogens.E) The embryo is protected from ultraviolet light.arrow_forward
- Phytochrome is a plant pigment protein that: a. mediates plant infection b. promotes plant growth c. mediates morphological changes in response to red and far-red light d. inhibits plant growtharrow_forwardFollowing infection with a pathogen, one response is to spread an alarm signal to increase defenses and antimicrobial compounds throughout the plant body and the network of plants connected by mycorrhizae. Which chemical spread this alarm signal? Select one: a. Salicylic acid b. Jasmonic acid c. Indole acetic acid d. Gibberellic acid e. Abscisic acidarrow_forwardStomata (a) help prevent desiccation of plant tissues (b) transport water and minerals through plant tissues (c) allow gas exchange for photosynthesis (d) strengthen cell walls (e) produce male gametesarrow_forward
- Black spot fungus is a disease that is known to attack roses in humid climates. At first, small black spots appear on the leaves. If left untreated, the entire plant can die. From this information, what is mostly the main cause of the demise? a) The plants’ cells are unable to carry out aerobic respiration. b) The leaves are unable to manufacture enough sugar to maintain the health of the plant. c) The roots are unable to absorb enough water. d) The stems are unable to support the plant.arrow_forwardHow can insects make plants more susceptible to pathogens?arrow_forwardWhich of the following best describes evidence of a hypersensitive response? Select one: a. The bending of the coleoptile towards light. b. The growth of roots down and shoots up. c. When cells around an infection site die, depriving the pathogen of nutrients and preventing it from spreading. d. When plants elongate in response to being shaded. e. When stomata close despite plenty of CO 2 and water.arrow_forward
