Plants have three basic types of tissues: The fundamental tissues are the plant tissues responsible for nutrition. They are found in all plant organs and are made up of living cells with large vacuoles. The epidermal tissue is the one that covers the roots, stems, leaves and other organs of plants. It is a thick layer with flattened and attached cells. It is lined with a wax-like lipid-rich cuticle that prevents water loss. Conductive tissues make up the vascular system of the plant. They are made up of specialized transfer cells.

Explanation:

The fundamental tissue comprises the main part of the body of the plant. Parenchymal cells (the most abundant), cholenchymal and sclerenchymal cells constitute the fundamental tissues. The cells of the parenchyma located in leaves, stem and root; responsible for photosynthesis or storing substances. Collenchyma cells also form this type of tissue, and their function is to support the stems of herbaceous plants. Sclerenchyma cells have cellulose primary and secondary walls, providing great rigidity and firmness, which is why it is only found in woody plants.The epidermal tissue covers the external surfaces of herbaceous plants, it is composed of tightly united epidermal cells that secrete a layer formed by cutin and waxes called cuticle that prevents the loss of water. Stomata, trichomes and other types of specializations can be seen in it.Vascular tissue, xylem and phloem, are made up of parenchymal cells that store food and water, as well as conduction cells and supporting fibers. Phloem conduction cells transport the products of photosynthesis, mainly sucrose, from leaves to non-photosynthetic cells; xylem cells carry water and minerals from the roots to other parts of the plant.

Environmental science studies the interactions between the physical, chemical, and biological components of the environment, including their effects on all types of organisms. earth science (also known as geoscience), is an inclusive term for all sciences related to earth (geology, meteorology, oceanogr maphy, etc). although environmental and earth science cover essentially the same material, environmental science places greater emphasis on the biological realm, while earth science places greater emphasis on the physical realm. environmental and earth science study the interactions of four major systems or “spheres” (figure 8.6). the geosphere consists of the core, mantle and crust of the earth.the atmosphere contains all of the earth’s air and is divided into troposphere, stratosphere, mesosphere, thermosphere and ionosphere.the hydrosphere contains all of the solid, liquid and gaseous water on earth, extending from the depths of the sea to the upper reaches of the troposphere where water is found. ninety-seven percent of the hydrosphere is found in salty oceans, and the remainder is found as vapor or droplets in the atmosphere and as liquid in ground water, lakes, rivers, glaciers and snowfields. the biosphere is the collection of all earth’s life forms, distributed in major life zones known as biomes: tundra, boreal forest, temperate deciduous forest, temperate grassland, desert, savannah, tropical rainforest, chaparral, freshwater, and marine.although the four systems have their unique identities, there is substantial interaction between them. environmental scientists study the effects of events in one sphere on the other spheres. for example, a volcanic eruption in the geosphere may cause profound direct and indirect effects on the hydrosphere, atmosphere and biosphere as follows: example 1 (volcano) on may 18, 1980, mount saint helens, in the state of washington, erupted. this event altered the surrounding environment, and provided scientists with an opportunity to study the effects of volcanic eruptions on the geosphere, hydrosphere, atmosphere and biosphere. such studies are vital because volcanic eruptions will continue to occur, and will have increasing impact on humans as people continue to settle lands closer to dormant volcanoes. the following are but a few of the myriad of interactions resulting from a volcanic

Part a - which gene to compare? in this exercise, you will use the cytochrome c oxidase i (coi) gene to investigate relationships among salmon species. (this gene encodes a protein that functions in the mitochondrial electron transport chain.) you will compare the coi gene sequences from your salmon test samples to the standard sequences for each salmon species. in order for the coi gene to be useful for distinguishing among the different salmon species, which three statements must be true?
