Alan Watson Mrs. Lefever Biology 19 April 2010 Maple Syrup Urine Disease I. General Information -Maple Syrup Urine disease is an inherited disorder in which the body does not and is unable to process certain protein building block called amino acids leucine‚ isoleucine‚ and valine. -To treat this disease the infected would have to have a protein-free diet. Fluids‚ sugars and possibly fats are given through a vein (IV). II. Nature of this Mutation -Symptoms of this

INSECTIVOROUS PLANTS An insectivorous plant‚ also called a carnivorous plant‚ captures prey items‚ such as insects‚ spiders‚ crustaceans‚ mites‚ and protozoans‚ as a nitrogen source. Many insectivorous species live in freshwater bogs‚ where nitrogen is not present in available form‚ because the pH of the water is extremely acid. The forms of entrapment by these types of plants are modified leaves. Five basic trapping mechanisms are found in carnivorous plants. 1. Pitfall traps (pitcher plants) trap prey

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

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

Is this one galaxy or two? This question came to light in 1950 when astronomer Art Hoag chanced upon this unusual extragalactic object. On the outside is a ring dominated by bright blue stars‚ while near the center lies a ball of much redder stars that are likely much older. Between the two is a gap that appears almost completely dark. How Hoag’s Object formed remains unknown‚ although similar objects have now been identified and collectively labeled as a form of ring galaxy. Genesis hypotheses include

Bacterial leaf blight Xanthomonas oryzae pv. oryzae The bacterium is aerobic‚ gram negative‚ non spore forming‚ rod with size ranging from 1-2 x 0.8-1.0µm with monotrichous polar flagellum. Bacterial colonies are circular‚ convex with entire margins‚ whitish yellow to straw yellow colored and opaque. Favorable Conditions Clipping of tip of the seedling at the time of transplanting Heavy rain‚ heavy dew‚ flooding‚ deep irrigation water Severe wind and temperature of 25-30 C Symptoms: Seedlings

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.) There

from the aerial parts of plants‚ especially leaves but also stems‚ flowers and roots. Leaf surfaces are dotted with openings called stomates that are bordered by guard cells. Collectively‚ the structures are called stomata.[1] Leaf transpiration occurs through stomata‚ and can be as a necessary "cost" associated with many processes such as the opening of the pistil and allowing the diffusion of carbon dioxide gas from the air for photosynthesis. Transpiration also cools plants and enables mass flow

TOMATO PLANT 1) Seed: Tomato seeds are small‚ flat and disk shaped and about 1/8 inch wide. They contain two energy storage organs called cotyledons and an embryo encased in a hard outer shell called the seed coat. The seed is the dormant or resting stage of the plant life cycle. When young tomato plants are damaged‚ they tend to go into a dormant‚ survival stage in which plant growth is delayed for a while. Frost damage is something to look out for when planting tomatoes early on in the season
