Hydrilla verticillate 4. Solanum melongena L. 6. Capsicum frutescensFigure 24.17 Which of the following statements is true? A basidium is the fruiting body of a mushroom-producing fungus, and it forms four basidiocarps. The result of the plasmogamy step is four basidiospores. Karyogamy results directly in the formation of mycelia. A basidiocarp is the fruiting body of a mushroom-producing fungus.As noted in Section 46.7, mycorrhizal fungi help prevent carbon in the soil from escaping into the atmosphere. These fungi also benefit a host plant by providing it with a share of the phosphorus and nitrogen that their hyphae take up from soil. Most crop plants are capable of forming a relationship with mycorrhizal fungi, if any are present in the soil. Some people have suggested that inoculating soil with fungal spores could help reduce the use of industrially produced fertilizer. What are some potential advantages of using fungi, rather than chemical fertilizers, to enhance plant growth?

Length of the setaComplete the following paragraph to describe the characteristics of liverworts and mosses. antheridia protonema rhizoids sexual gemmae roots archegonia fragmentation asexual 1999 binary fission gemmules thalli Reset Help Liverworts and mosses are examples of nonvascular plants. Liverworts such as Marchantia have a smooth upper surface, and a lower surface with that project into the soil. The smooth upper surface of the thallus of a liverwort contains groups of cells called cups that can produce new plant organisms asexually. During sexual reproduction in liverworts, flagellated sperm are produced by and eggs are produced by After fertilization, small sporophytes produce windblown spores. Typically, mosses can reproduce asexually by almost every part of the moss plant to produce During the life cycle of a moss, a its structure. This process allows will produce upright leafy thalli along The thalli of a moss produce antheridia and archegonia, which are involved in reproduction.
