- What is the genetic load in angiosperms and gymnosperms of the following structures: Microsporophyll Microsporangium Microsporocyte Microspora Microgametophyte Megasporophilic Megasporangium Megasporocyte Megaspore MegagametophyteMost of the approximately 900 species of gymnosperms are conebearing plants. On the surfaces of their cone scales are ovules, which later become seeds. These ovules are said to be naked because they are not completely enclosed by diploid tissue (as the ovules of angiosperms are). This characteristic gives the gymnosperms their name; gymnos is a Greek word meaning naked, and sperma means seed. Botanists now divide the gymnosperms into four groups: conifers, cycads, ginkgos, and gnetophytes.1) For each of the organisms in the following table, complete the empty columns with an appropriate answer for each taxa.

Which plant group would you place this species? O pteridophyte O basidiomycete O bryophyte angiosperm O gymnosperm MacBook Pro Search or type URL 2$ 4 7 8Using appropriate examples, discuss the diversity of forms amonggymnosperm lineages
- List FOUR examples of angiosperm and/or gymnosperm plant species that are economically important. A species could have more than one use (for example, species "x" is an angiosperm and its tuber is used as food, for drink and at the same time it is medicinal). PUT A PHOTO OF EACH ONE, identify with common (or scientific) name.Monilophytes and seed plants both have megaphylls, as well as other traits not found in lycophytes. Explain this observation using the Figure in the picture and the concept of descent with modification.http://botit.botany.wisc.edu/botany_130/diversity/plants/mosses.html Make a complete moss life cycle with the following phases and structures. Note: download the images of Mnium from this link and arrange them in the exact sequence to make the lifecycle. Lifecycle structures with cell division: Meiosis, fertilization within archegonium, capsule (sporangium), spores (n), protonema (n) (Image), male gametophyte (n) (Image), female gametophyte (n) (Image), antheridia (Image), archegonia (Image), sperm, egg, water, zygote (2n), embryo, young growing sporophyte (2n), mature sporophyte (2n) (Image), rhizoids.

- Describe 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.The male gametophyte of the moss looks identical to the female from the naked eye, but the photo below (I.s. at 4x and then at 40 x) shows that the tip contains the structures where male gametes are produced.Linnean- or rank based classification systems have placed the cycads, ginkgo, conifers and gnetophytes, respectively, into separate categories, of equal ranking (i.e., each gymnosperm group a Phylum or Division). Is the Linnaean classification of each gymnosperm group justifiable, based on the information shown in the figures?
