One of the genera of Lycophytes are the Selaginellaceae. Like other Lycophytes, Selaginellids bear their spores in a strobilus but they have an unusual strobilus. Which answer below best describes this difference? O their spores are always diploid O they are gaemtophyte dominant O their spores are heterosporous O their strobilus is dependnent upon the female gametophyte like mosses APR 25 étv MacBook Pro G Search or type URL @ #3 % %24
Label the diagram which features an illustration of a portion of the sporophyte of Selaginella with strobili, and a photomicrograph of the longitudinal section of a mature strobilus. Indicate whether each of the structure you identified is haploid (n) or diploid (2n)
One of the genera of Lycophytes is Selaginella. Like other Lycophytes, Selaginellids bear their spores in a strobilus but they have an unusual strobilus which sets them apart from their relatives. Which answer below best describes this distinction? their spores are always diploid O they are gametophyte-dominant their spores are heterosporous their strobilus is dependnent upon the female gametophyte like mosses
The photo below is a longitudinal section (I.s.) of the strobilus of Selaginella at 40x. How does this photo illustrate the importance of the previous question?
Explain the following bullets: Division Cycadeoidophyta: Cycadeoids The cycadeoids (all extinct) had vegetative features almost identical to those of cycads. However, individual cones of cycadeoids contained both microsporophylls and megasporophylls
Distinguish among fungi that are haploid, dikaryotic, or diploid by completing the following statements, referring to the figure as necessary. n+n sexual n diploid contains paired haploid nuclei dikaryotic 2n A haploid asexual Saved B Fungi reproduce both sexually and asexually. In terrestrial fungi, reproduction occurs in three stages. One stage, depicted in part A of the figure above, is termed point each cell is First, days, months, or years, the Another stage, depicted in part B of the figure above, is termed stage takes its name from the term for a hypha that each cell is C at which 20 hyphae pair up. Sometimes immediately, other times after hyphae make contact and fuse...

When the hyphae of two compatible club mushrooms (Basidiomycota) fuse, the result is hyphae that is; Diploid N + N Соenocytic Нaploid
The basidium of the club fungi could be correctly described as; A reproductive structure that produces diploid spores A sexual reproductive structure that produces 4 haploid spores An asexual reproductive structure that produces thousands of spores A sexually reproductive structure that produces 8 haploid spores
Relate plasmogamy and karyogamy to the process of fertilization and describe whey we need to separate these two things in the life cycle of the fungi. Differentiate between the monokaryotic and dikaryotic conditions. Compare and contrast an animal life cycle with that of a typical mushroom including the haplophase, dikaryophase, and diplophase, products of meiosis, plasmogamy, and karyogamy.
e th aci st SJ I the size, shape, and arrangement of the leaves, which are microphylls, small leaves with only one vein. Examine the roots and their relationship to the stem. In Selaginella, the roots grow downward from a leaf-bearing stem. The sporangia of the Lycopodiophyta are borne on leaves essentially similar to the sterile leaves of the plant. The sporangium bearing leaf is called a sporophyll. In Selaginella and Lycopodium, the sporophylls occur in compact aggregates called cones, or strobili. 1. Label the microphylls and strobili in the Figure 1 below. Figure 1. Lycopodium sp. Examine the prepared slide of a mature Lycopodium strobilus. (See text Figure 17-16, pages 406 and 407.)

Complete 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.
