Explain it by bullet. 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

true or false. The fern stage on the right side of the life cycle is the gametophyte
The picture below is of a moss growing on my roof. It shows both the gametophyte and the sporophyte phases of the life cycle. Make a sketch and label which part of the moss is the gametophyte and which is the sporophyte. (Alternatively, you can find a live moss with both phases and take a picture, label it and upload here.) Label the seta, capsule and calyptra of the sporophyte.

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?
True or false The fungal component of a lichen thallus is most often a basidiomycete. In eucarpic thallus, the entire thallus is composed mainly of sporangia. The tree fern, Cyathea is a eusporangiate fern. The trophophyll vegetative frond has the same morphology and function as the sporophyll frond. Tricolpate pollen morphology is a synapomorphy in all dicots. Hyphal tissue comprise the medulla layer of a lichen thallus. The Phylum Ascomycota is a monophyletic group. Homosporous condition in the sporophyte gives rise to bisexual gametophyte. The Phylum Basidiomycota is a paraphyletic group. In polycentric thalli, a single zoospore will give rise to several rhizoids. Heterothallic mycelia require two different, but compatible, mycelia to reproduce sexually. Having a single cotyledon is a synapomorphy shared by all monocots. The xylem vessel is considered an apomorphic feature in the monocots and eudicots. The nuclear fusion of the dikaryotic hyphae is termed as plasmogamy. In…
True or false: If false, state the right answer. 1. Heteromorphic plants produce male and female gametophytes. 2. A sporangium produces spores, no matter what group it is located. 4. In lycophytes, roots branch only at the growing tip of the root, forming a U-shaped structure. 5. Polytrichum moss greatly reduced the loss of oxygen by leaching in this ecosystem. 6. Most ferns are heterosporous, although the archegonia and the antheridia on the small photosynthetic gametophyte mature at different times ensuring cross fertilization. 7. Bryophyte rhizoids lack specialized absorptive cells and do not play a primary role in water and mineral absorption. 8. Plant spores are haploid reproductive cells that can grow into multicellular haploid gametophytes by meiosis. 9. The multicellular, dependent embryo of land plants is such a significant derived trait that land plants are also known as embryophytes. 10. Cells produced by apical meristems differentiate into the outer epidermis, which…

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
