1. Unlike some groups under the chlorobionta, the land plants (also called Embryophyta) constitute a monophyletic group within the green plants. 2. The venter is a sterile layer that surrounds the antheridial wall.

TRUE OR FALSE 1. Vascular plants evolved to have the apomorphic characteristics that enabled them to grow with greater height and thrive with efficiency in sustaining more complex structures. 2. One evident apomorphy evolved in vascular plants is the establishment of true leaves which is characterized by the incorporation of the vascular system.
True or Falsea. The Phylum Glomeromycota is fungi that produce sexual spore in their asci. b. Gymnosperms seeds has a higher chance of survival rate even the dormancy period is prolonged c. The only living genera of Division Psilophyta are: Lycopodium and Psilotumd The gametophyte of mosses is differentiated into protonema and foliose gametophere.
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
1. The chloroplast morphology in the genus Spirogyra. 2. This refers to the conjugation between two filaments of Spirogyra. 3. It refers to the conjugation of two adjacent cells of Spirogyra. 4. A cell division characteristic of the Charophyta and higher plant marked by the breakdown of the nuclear envelope early in mitosis. 5. A cell division characteristic of the chlorophytes whereby nuclear envelope remains intact early in mitosis. 6. It refers to the parallel arrangement of microtubules relative to the plane of cell division during cytokinesis in the Chlorophyta. 7. It refers to the perpendicular arrangement of microtubules relative to the plane of cell division during cytokinesis in the Charophyta. 8. The genus of the green alga commonly known as sea cockroach. 9. The specific part of the desmid cytoplasm where the nucleus is confined. 10. The genus of the green alga commonly known as the sea lettuce.
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…
