Figure 25.14 Which of the following statements about the moss life cycle is false? The mature gametophyte is haploid. The sporophyte produces haploid spores. The calyptra buds to form a mature gametophyte. The zygote is housed in the venter.
Mycorrhizal fungi live in the soil and interact with the roots of plants. Essentail nutrients (e.g. nitrogenous compounds) are taken from the soil by the fungi and transferred to the plant roots. The fungi extract carbohydrates from the plant roots. What type of interaction is occurring?
Which of the following statements is true regarding mycorrhizal relationships? this relationship is a type of parasitism bacteria partner with plant roots fungi provide energy (ATP) for their partner all glomeromycota are mycorrhizal fungi no statements above are true
Which of the following is NOT a reason why fungi can grow so quickly? Group of answer choices external digestion of food particles hyphae with incomplete or no cells walls between cells a huge number of hyphae a very small SA: V ratio very thin hyphae
#4 What do hyphae do for a plant partner in a mycorrhizal association? 1.they decrease the surface area for absorbing food for the plant 2.they increase the surface area for absorbing food for the plant 3.they decrease the surface area for absorbing water and nutrients for the plant 4.they increase the surface area for absorbing water and nutrients for the plant
Fairy rings (such as the one in the photo on the left) are circles of fungi that often appear in open meadows and in forest areas. In the soil beneath the fungi is an ever-extending mycelium. As the mycelium spreads to seek out more food, it sometimes will produce the fungi we see above ground to produce and release spores. The diagram on the right depicts the outline of a fairy ring that has appeared overnight in an open meadow, as viewed from above. The ring represents the farthest advance of this mycelium through the soil. The letters A-D represent locations with respect to that ring which are all 0.5 meters below the soil surface. Which location (A-D) is nearest to the basidiocarps? ___ What is the most probable location (A-D) of the youngest portion of this mycelium? ___
