    Introduction Plants are autotrophs which make their own, organic nutrients, to sustain themselves, through a complex process known as photosynthesis. The plant kingdom is diverse and is made of plants of different biological diversity (Raven et al. 2005). Cryptograms or Seedless plants are vascular plants that do not produce seeds for dispersal but reproduce by windblown spores. In seedless plants the gametophyte and sporophyte are both independent phases in the plant’s life cycle. Like all vascular plants

    seed-bearing vascular plants that play a key role in the function of organisms within any given ecosystem. These plants vary in shape and size and tend to interact with other organisms in the root environment (Hemsley, 2004). The underground root environment works in conjunction with the above ground shoot system; these systems work together to allow the whole plant to grow, develop, and function. Vascular plants would not be nearly as successful as they are without the anatomy of plant stomatal leaf

    A comparative review of the vascular system in seed plants and humans In the evolutionary tree of life, all biotic organisms are believed to have derived from a common ancestor. The organisms falling under the eukaryotic kingdom of Plantae are known to have arisen in the same time period as those in the eukaryotic kingdom of Animalia—the Paleozoic era, about 500 million years ago (MYA) (Raven et al., 2008). Despite their chronological resemblance, their evolutionary diversity

    rhizoids are root like structures that absorb water to bring up to the plants and transport materials. 3. The position of the archegonium and antheridum relate to their reproductivbe function by having archegonium have their eggs under them so when the antheridum sperm is dispersed it will reach the egg better. Antheridum are upright so that the sperm is dispersed on top to be able to reach the archegonium egg and fertilize the plant. They are also located near each other so that when there is rain fall

    Non Vascular Plant Non vascular plants are huge in the evolution of plants, because they begin the move of plants onto land. There are not a lot of characteristics that distinguish non vascular plants from other plants, but these characteristics did allow non- vascular plants to separate themselves from the previous group composed largely of algae. The four traits that we see begin to develop are apical meristems, walled spores, gametangia, and one of the most common called alternation of generation

    papyrus: From the Nile to Modern Times Cyperus papyrus, commonly called papyrus or paper plant, is a member of the sedge family (Cyperaceae). It is a monocot that is native to riverbanks and other wet soil areas in Egypt, Ethiopia, the Jordan River Valley, and other parts of the Mediterranean basin (1). Few members of the sedge family hold economic importance as crop plants, but throughout the world these plants hold great regional importance in weaving mats, baskets, screens, and even sandals (3)

    The biggest solution is to start to use green house farming. Green house farming was developed around 30 A.D. It was developed by the ancient royal Roman physicians who constructed a specularium. This specularium was a house dedicated to growing plant and maintained fires outside the stone walls to heat the air inside. It also had a translucent roof crafted from thin sheets of mica which allowed the sunlight to go through.[1] This then over the years got transformed into the modern day green house

    Germination is the process of the plant embryo sprouting a seedling after a period of dormancy in a seed. (The Columbia Encyclopedia, 6th ed., 2008) Dormancy comes from the Latin word meaning “to sleep.” This period of inaction in the seed is an adaptation to support the seed so it can survive though the harsh growing conditions. (Campbell, Reece, Urry, Cain, Qasserman, Minorsky & Jackson, 2008) Once these poor conditions are absent, the seed can then germinate. The seed will absorb the water

    dugongs graze on seagrasses that form meadows in coastal waters. As dugongs feed, whole plants are uprooted and a telltale feeding trail is left behind. These feeding 'scars' in the seagrass can be easily seen by people walking over the seagrass areas at low tide (Great Barrier Reef Marine Park Authority [GBRMPA]). The dugong feeds almost exclusively on a number of genera of seagrasses, especially the marine vascular grasses Halodule and Halophilia. These grasses are low in fiber, high in available nitrogen
