    Plants, also called green plants (Viridiplantae in Latin), are living organisms of the kingdom Plantae including such multicellular groups as flowering plants, conifers, ferns and mosses, as well as, depending on definition, the green algae, but not red or brown seaweeds like kelp, nor fungi or bacteria. Green plants have cell walls with cellulose and characteristically obtain most of their energy from sunlight via photosynthesis using chlorophyll contained in chloroplasts, which gives them...

    The Plant Kingdom (Plantae) (Last modified: 20 June 2007) Plants provide nourishment for our bodies and souls. With the help of protists and fungi, plants provide the oxygen we breathe and the food that sustains us -- either directly or indirectly, by feeding other animals. Plants provide shade over our heads and cool carpets under our feet while surrounding us with beautiful colors and marking the change of seasons. Prominent plants give us a handle on ecological communities. Descriptions...

    Cloning is asexual reproduction. Cuttings are taken from a mother plant in vegatative growth, and rooted in hydroponic medium to be grown as a separate plant. The offspring will be plants that are identical to the parent plant. Cloning preserves the character of your favorite plant. Cloning can make an ocean of green out of a single plant, so it is a powerful tool for growing large crops, and will fill a closet quickly with your favorite genetics. When you find the plant you want to be your...

    There are more to aquatic plants than just floating on the surface of water. Aquatic plants are plants that can adapt and live in a freshwater environment. They are sometimes called hydrophytes. These include plants that live in fresh wetlands, swamps, ponds, lakes, and marshes. This type of plant actually serves two important functions. First, they help oxygenate water (2006) and they provide nutrients and food for some fishes (Tappin, 2003). There are many types of aquatic plants including...

  • Evolution of Plants - 11751 Words
    The evolution of plants has resulted in increasing levels of complexity, from the earliest algal mats, through bryophytes, lycopods, ferns to the complex gymnosperms and angiosperms of today. While the groups which appeared earlier continue to thrive, especially in the environments in which they evolved, each new grade of organisation has eventually become more "successful" than its predecessors by most measures. Probably an algal scum formed on land 1,200 million years ago. In the Ordovician...

    The three main organs in a plant are roots , stems, and leaves. Roots absorb water and dissolved nutrients from soil. They anchor plants to the ground. Roots are able to do all of these jobs because they grow , they develop complex branching networks that penetrate the soil and grow between soil particles. Stems hold a plants leaves up to the sun. Leaves are the organ in which plants capture the suns energy. These tissues must be protected against water loss to dry air. That’s why most plants...

    Role of mycorrhizas in the mineral nutrition of host plants Mycorrhizas are very important in the uptake of nutrients such as P, N, K, Cu, Zn and Ca by plants especially in soils low in these nutrients. Since P is the most limiting nutrient in tropical soils, mycorrhizas are vital for improving P nutrition particularly for cultivated plants. External hyphae can absorb and translocate P to the host from soil outside the root depletion zone. The thin mycorrhizal hyphae (2-4 μm in diameter) are...

    Plant cells are eukaryotic cells that differ in several key aspects from the cells of other eukaryotic organisms. Their distinctive features include: A large central vacuole, a water-filled volume enclosed by a membrane known as the tonoplast maintains the cell's turgor, controls movement of molecules between the cytosol and sap, stores useful material and digests waste proteins and organelles. A cell wall composed of cellulose and hemicellulose, pectin and in many cases lignin, is secreted...

    Carnivorous Plants In a world where plants are at the bottom of the food-chain, some individual plant species have evolved ways to reverse the order we expect to find in nature. These insectivorous plants, as they are sometimes called, are the predators , rather than the passive prey. Adaptations such as odiferous lures and trapping mechanisms have made it possible for these photosynthesizers to capture, chemically break-down and digest insect prey (and in some cases even small animals.)...

    Five hundred million years ago, the invasion of land was under way. Why then? Astronomical numbers of photosynthetic cells had come and gone, and oxygen-producing types had changed the atmosphere. High above Earth, the sun’s energy had converted much of the oxygen into a dense ozone layer, a shield against lethal doses of ultraviolet radiation. Until then, life had not ventured above the surface of water and mud. Algae were evolving at the water’s edge, and one group – probably the...

    Green plants absorb light energy using chlorophyll in their leaves. They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration, or converted into starch and stored. Oxygen is produced as a by-product. This process is called photosynthesis. Temperature, carbon dioxide concentration and light intensity are factors that can limit the rate of photosynthesis. Plants also need mineral ions, including nitrate and magnesium, for healthy growth....

  • Bryophytes Are Seedless Plants Without
    DISCUSSION Bryophytes are seedless plants without specialized water conducting tissues. Bryophytes include mosses (phylumBryophyta), liverworts (phylum Marchantiophyta Hepatophyta), and hornworts (phylum Anthocerophyta). They are plants that virtually everyone has seen, but many have ignored. The most commonly encountered group is the green mosses that cover rotting logs, anchor to the bark of trees, and grow in the spray of waterfalls, along streams and in bogs. Even though mosses often thrive...

    Some of the most bizarre and fascinating plants in the natural world are undoubtedly carnivorous plants. Carnivory, defined as the consumption of animal tissue, is often only associated with the animal kingdom. However the existence of carnivory is widespread and diverse in the plant and fungi kingdoms as well. Specifically carnivorous plants, which originally descended from exclusively photosynthetic plants, have evolved elaborate, efficient, and diverse methods to capture, digest, and...

    1. Water diffuses into a plant through its root hairs and then travels into the parenchymal cells of the cortex along the symplast and the apoplast. Then the water moves to the endodermis where it freely passes into the vascular cylinder and into the xylem. Once the water is in the xylem it moves upward toward the leaves. Then the water diffuses from the roots where the water potential is the highest to the air spaces in the leaves where the water potential is the lowest. From the veins in the...

    Experimental Design Bio 1110 ! ! Background: Plants need water to survive. Water makes up 80-95% of the mass in plant tissues. Transpiration is the loss of water from plants in vapor form. 95% of the water is absorbed from the soil for transpiration and 5% is absorbed during photosynthesis for producing necessary carbohydrates for growth. The rate of transpiration is dependent on the amount of water in which is available within the plant, soil, and on sufficient energy to vaporize...

    Literature research on the response to plant organs to the environmental stimulus of light. Phototropism is the growth of organisms the response to light. The cells on plant stems have a chemical called auxin. These auxins react when phototropism occurs. This in turn results in plants having elongated cells on the side of the plant furthest away from sunlight. Phototropism is one of many tropisms that respond to external stimuli. Examples of other tropisms are (chemotropism, geotropism and...

    Plants need water for photosynthesis but they take in water through their roots so they need to transport the water up the stem to the leaves. Water is taken in by the root hairs because there is a higher water potential in the soil than in the root hairs. Then osmosis occurs to move the water from a cell with high concentration of water to a cell with low concentration through the permeable membrane. Once the water has moved down the concentration gradient it reaches a vessel called a xylem....
