Botany Essay Questions 1. Pollination is a crucial process of how plants reproduce‚ in which the male sex cell of the flower‚ pollen‚ is transferred from the stamen to the carpel‚ or more specifically‚ from the anther to the stigma. Pollen grains are completely different and unique for each flower‚ they carry the male and female genetic information and it is split exactly 50/50. The transfer is carried out by pollinators‚ which include bees‚ wasps‚ flies‚ butterflies‚ moths‚ several species

for plants‚ and one small section of the electromagnetic radiation spectrum‚ is called the Photosynthetically Active Radiation (PAR)‚ provides the energy to drive the light reactions of photosynthesis. Such radiation damages biological tissues by detaching electrons from the atoms that make up organic molecules. The results include radiation poisoning‚ cancer‚ and elevated mutation rates. Scientists use ionizing radiation to increase gene mutation rates in experimental organisms such as plants. The

The factors affecting plant yield: light level Abstract The factors affecting Zea mays‚ maize (C4) and Pisum sativa‚ or pea (C3) plant yield and growth patterns placed under shade and full sunlight were investigated. 20 plantlets placed into four vermiculite compost pots (5 from each plantlet) and submitted to fertilizer or no fertilizer. And after 4 weeks the results showed that maize grown in light with no fertilizer had a higher relative growth rate and root to shoot ratio indicating the allocation

Animal and Plant cells consist of most of the same cell types‚ but the whole shape of the cell is quite different. An animal cell is a round‚ uneven shape‚ whereas the Plant cell has an affixed shape. They have a more of a rectangular shape. Chloroplast‚ Vacuole and the Cell wall are only found in Plant cells. The Chloroplast is the organelle for the whole system of Photosynthesis. Chloroplasts are found in mesophyll cells (which are found in the leaves) of green plants. They convert light into

TRADITIONAL DYE PLANTS OF MANIPUR Sanjeev Rana Knitwear Department‚ National Institute of Fashion Technology Abstract Manipur is one of the richest states in plant biodiversity in the North Eastern states of India. Different ethnic groups‚ residing in Manipur before the introduction of the chemical dyes into the state‚ used the dyes extracted from the plants. Women in Manipur practice dyeing using varieties of plant leaves‚ flowers and tree barks. The natural dyes were obtained from plants and have

This paper is about how the plant cells and solar cells are similar to each other as well as how they are different to one another. In addition this paper explains how the laws of thermodynamics apply to each of the plant and solar cells system. Plant Cells and Solar Cells Photosynthesis is the process of producing and releasing oxygen in the air. It needs sunlight‚ carbon dioxide and

Built in 1923 as a coal-powered operation‚ the High Bridge plant‚ along with Riverside in Minneapolis‚ once formed the hub of Northern States Power Company‚ a predecessor to Xcel Energy. The original plant was replaced with a new natural gas fired generating facility starting in 2005 as part of Xcel Energy’s Metro Emission Reduction Project. The coal-fired plant was retired in 2007 and the new facility came on line in May 2008. (High Bridge Generating Station) One interesting feature about the

The Engstrom Auto Mirror plant employs over 200 people at its Indiana location. In May 2007‚ the Engstrom Auto Mirrors plant‚ a relatively small supplier based in Indiana‚ faces a crisis. The business was in the second year of a downturn. Sales had started declining since 2005; a year later‚ plant manager Ron Bent had been forced to lay off more than 20 percent of the work force. Plant productivity was dropping‚ employee morale was low‚ and product-quality issues had begun to surface. Relationships

of this experiment was to prepare a wet mount of human cheek cells and a wet mount of plant cells and examine them both under a compound microscope. Introduction: Cells are the basic units of life which make up every structure in the human body. They are the smallest units which are living. All cells contain different organelles which carry out different functions. Plant and animals vary slightly. Plant cells consist of a nucleus‚ chloroplasts‚ cell wall‚ cell membrane a large vacuole and
