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

Genetically Modified Crop Plants Biology 115 Genetically Modified Crop Plants Genetically modified crop plants and animals have great potential to change the world we live in. I believe that genetically modified crop plants can cure world starvation and at the same time improve the quality of food production. I recall when Senator Ron Paul was a presidential candidate in 2008 and student asked him his stances on genetically modified food products. His reply was “Big businesses

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

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

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

Plant-Animal Coevolution Evolution Charles Darwin gave what could be described as a loose definition of evolution when he wrote “descent with modification” (Darwin‚ 1859). Evolution is defined more specifically as a change in the genetic composition of a population‚ from generation to generation (Reece et al.‚ 2011). In this investigation into coevolution‚ in particular plant-animal coevolution‚ the adaptations and reasons for these adaptations in a specific example of plant-animal coevolution will

How Does Climate Change Affect Plants? Historical climate change has had a profound effect on current biogeography‚ so we can expect our ongoing and rapid climate change‚ to have as great an effect. Climate change has important implications for nearly every aspect of life on Earth‚ and effects are already being felt. * Temperatureeffects–average‚ minimum or maximum can be important determinants of plant distribution For example the Palmae/Arecaceae are cold intolerant as their single meristem
