- 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.Complete the table below and do not exceed in two sentences. Characteristics Cycads Ginkgo Conifers Gnetum Distinct features of the sporophyte Monoecious or Dioecious Dioecious Dioecious Monoecious Dioecious Pollination/Pollinating Agents Beetles and small bees. It can also be through Anemophily Mammals and birds Pollinated by wind They are pollinated via insects.

Choose 3 The columella is absent in the capsule Pseudolaters are present in the capsule gametophyte plant is either thalloid or foliose dehiscence of the capsule takes place by separation of the lid each cell has one chloroplast with a pyrenoidDescribe the orders ANGIOSPERMS-EUDICOTS : ERICALES, GENTIANALES, LAMIALES, SOLANALES, APIALES AND ASTERALES in terms of plant habit, reproductive type (monoecius/dioecius), leaf type, leaf shape, floral characteristics, fruit morphology, seed size/shape, and other distinct features.
- 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)Describe the orders under the gymnosperms (Cycadales, Ginkgoales, Coniferalesn and Gnetales) in terms of plant habit, reproductive type (monoecius/dioecius) leaf type, leaf shape, seed size/shape, special seed characteristics, cone morphology and other distinct features.Explain the following bullets: Division Cycadophyta: Cycads Internally, cycad stems are similar to those of seed ferns—a thick cortex containing secretory ducts surrounds a small amount of manoxylic (parenchymatous) wood. Unlike seed ferns, cycad foliage leaves do not bear ovules. Cycads produce seed cones and pollen cones, each on separate plants. Seed cones are variable, with those of Cycas revoluta usually considered the most relictual. Although Cycadophyta was a much larger group with many more species in earlier times,currently, it contains 9 or 10 genera and approximately 100 species.• They are almost all tropical with an unusual distribution; some occur in Cuba and Mexico, others in Australia, still others in southeast Asia or Africa.
- Differentiate the reproductive structures and processes of the four plant representatives according to the categories provided. Bryophye Pteridophyte Gymnosperm Angiosperm Female reproductive structure and distinguishing characteristic Male Reproductive structure and distinguishing characteristicDraw a simple diagram illustrating a heterosporous life cycle. Include the sporophyte generation, megaspore, female gametophyte, egg, microspore, male gametophyte, sperm, meiosis, and fertilization. Be sure to indicate whether each generation or kind of cell is haploid or diploid.Figure 25.24 Which of the following statements about the fern life cycle is false? Sporangia produce haploid spores. The sporophyte grows from a gametophyte The sporophyte is diploid and the gametophyte is haploid. Sporangia form on the underside of the gametophyte.
