Essays on Conifers

1. Agiosperm wood has vessels as compared to conifers wood. Vessels can be defined as cells stacked end to end. Water is able to flow freely among them and otherwise vessels are called pores. However, conifers wood has resin canals that should not be confused with pores though they might look a little similar. Conifers wood is sometimes referred to as gymnosperms. 2. A. It is a part of sapwood. B. It is monocot. C. Monocots have inside their seed coats one seed leaf while dicots have two. Monocots’ leaves are thin due to the fact that the endosperm ...

Biomes/natural Vegetation: Needle-leaf Evergreen Forests

Needle-leaf evergreen forests are largely comprised of straight trunked, conical shaped trees that have comparatively shorter branches with narrow and small needle like leaves. These forests are composed of conifers predominantly. Where the needle-leaf forests are evergreen, they provide continuous deep shade to the ground, therefore, the lower layers of vegetation are either absent or sparse (Veregin 2005). Only a thick carpet of mosses can be found below the needle-leaf biome. There are very few species that can be found, however the large tracts of the vegetation have one or two species. According to the World Vegetation Map, this ...

Lesson 5 Answers:

24.) Plants are classified into four major groups: Bryophytes, Pteridophytes, Gymnosperms and lastly the Angiosperms. Bryophytes are the plants that do not have true vascular systems, which consist of the xylem and the phloem. In this group, includes the mosses, liverworts and hornworts. Together, they are considered as land plants that reproduce their own asexually by producing spores. Spores are produced in the ‘sporangium’ (plural sporangia), a bulb-like structure located at the top of the stalk. It can only be seen through the use of high powered microscope. Because they lack vessels that can bring the nutrients from the roots ...

Terrestrial Ecosystems Dynamic

Ecological systems are dynamic by nature and constantly feel the influence of climate variability. Since the structure and functioning of forest ecosystems are controlled by climatic factors through metabolic function, it may change in the future dynamics of forest restoration, growth, progress and growth of tree mortality, as well as the relationship of rocks. It is expected that climate change will be faster than the rate at which ecosystems can adapt and repair itself. Ecosystems of the North must first of all respond to possible global warming because of climate-driven ecosystem response reveals itself most clearly. At high ...

Part1: Medicinal or pharmaceutical Plants

1-Liverworts: From pedigree of embryophytes this plant is found throughout the world, especially in the tropic region. Few genera of this family are also aquatic. Liverworts grow on damp rocks and moist soil, while leafy liverworts habitat also on tree trunks in damp woods of low temperature, preferably in deep shades away from sunlight (Bidartondo & Duckett, 2009). Figure 1: Liverworts (Aphotoflora.com, 2014) 2-Ginseng (Panax ginseng): It is a deciduous perennial of North America and eastern Asia. Suitable average temperature for ginseng is 50°F ...
