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

you recommend that G.G. Toys change its existing cost system in the Chicago plant? In the Springfield plant? Why or why not? G.G. Toys should change its existing cost accounting system from traditional costing to activity-based costing (ABC) in the Chicago plant as it is allocating its entire manufacturing overhead on the basis of just one cost driver: production run direct labor cost. Since overhead at the Chicago plant is high‚ accurate cost accounting system is required. Different types of dolls

Enzymes and their importance in plants and animals (25 marks) Enzymes are biological catalysts‚ which accelerate the speed of chemical reactions in the body without being used up or changed in the process. Animals and plants contain enzymes which help break down fats‚ carbohydrates and proteins into smaller molecules the cells can use to get energy and carry out the processes that allow the plant or animal to survive. Without enzymes‚ most physiological processes would not take place. Hundreds of

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 New Plant Manager Toby Butterfield worked his way upward in the Montclair Company until he became assistant plant manager in the Illinois plant. Finally‚ his opportunity for a promotion came. The Houston plant was having difficulty meeting its budget and production quotas‚ so he was promoted to plant manager and transferred to the Houston plant with instruction to “straighten it out”. Butterfield was ambitious and somewhat power-oriented. He believed that the best way to solve problems

Auxin Auxin are essential plant hormones that promote the lengthening of the cell‚ which is a critical step before the cell goes through cell differentiation. The auxin can do this by increasing the amount of water taken in by the cell‚ which improves the elasticity of the cell and therefore can take more water and can get increasingly longer. And don’t think for a second that that’s all auxins do auxins may have been the first plant hormone to be discovered doesn’t make it the least important
