non-native plant in Southern California I research some information of Iris Pseudacorus which is commonly known as Yellowflag Iris. It is native to Europe‚ Western Asia‚ and northwest Africa. Especially‚ Pseudacours is one of two iris species native to British Island. It was brought to Canada and the U.S in the early 1900s in order to use as an erosion control plant such as used in sewage treatment cells. In recent decade‚ the plant is used in landscaping and sold through garden and plant dealers

Plant hormones are specialized chemical substances produced by plants. They are the main internal factors controlling growth and development. Hormones are produced in one part of a plant and transported to others‚ where they are effective in very small amounts. Depending on the target tissue‚ a given hormone may have different effects. Plant hormones play an integral role in controlling the growth and development of plants. A plant hormone is generally described as an organic compound synthesized

Guns‚ Germs‚ and Steel Europe’s geographic position was a key influence on its development. Not only was Europe close to the Fertile Crescent‚ but it also it contained climates and habitats that animals and crops could adapt to. In the 16th century‚ livestock animals that came from the Fertile Crescent dominated European farms. These animals included the cow‚ sheep‚ goat‚ horse‚ and many others. They served as a source of meat‚ milk‚ wool‚ manure‚ and muscle power. They transformed the productivity

Parts of plants Each part of a plant has a very important function. All plants produce flowers for the same reason: to make seeds so another plant can grow. Leaves: These are the parts of the plant where food is made by photosynthesis. Leaves take in carbon dioxide from the air‚ water from the soil‚ and energy from the sunlight. During photosynthesis‚ the leaves use light energy to change carbon dioxide and water into food. (sugar) Flowers: These are the reproductive parts of

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. They

CHAPTER 36 PLANT CELLS The first barrier to form between daughter cells is the middle lamella. Daughter cells expand to their final size and make polysaccharides for a primary wall. After expansion stops waterproofing materials are added for a secondary wall. Water and dissolved materials move from cell to cell by way of pit pairs. A pit is a thin spot in the primary wall where the secondary wall is absent or separated from the primary wall by a space. Strands of cytoplasm called

Materials and Methods The materials used included seeds of Wisconsin fast plants Brassica rapa‚ Styrofoam planting quads‚ potting soil‚ 14- 14- 14- NPK fertilizer beads‚ labeling tape‚ quad wicks‚ plastic water container with wick cloth‚ and anti-algal squares. To construct two different planters for our fast plants we used two Styrofoam planting quads. Each planter and squares inside of the planter were labeled. Each square was filled about half

PLANT BODY Two Categories of Plant cells: 1.) Meristematic cells – embryonic‚ undifferentiated and capable of cell division • Apical meristem – located at root and shoot ends • Lateral meristem – run parallel to the long axis of roots and stems – where somatic cells undergo mitosis 2.) Differentiated/Permanent Cells – specialized in structure and usually do not divide • Simple Permanent Tissue – dermal tissue system and ground tissue system › Dermal tissue system – outer surfaces of
