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
