Photosynthesis in Living Leaves

Words: 1061 Pages: 4 4981

Abstract The rate of photosynthesis can be measured by examining the amount of reactants and the buildup of products. Oxygen is a product of photosynthesis and is stored in the spongy mesophyll. This gives the organism the ability to float. In this experiment, oxygen is taken out of the spongy mesophyll. The leaves are then placed into the bicarbonate solution with soapy water. The spongy mesophyll fills with the solution, causing the leaves to sink. A light source was placed […]

Hardy Weinberg Lab Analysis

Words: 549 Pages: 2 4308

How does migration affect the allele frequency of the dominant allele? A genetic population can be described as the sum of allelic frequencies of all genes that are represented in the population. This implies that for an evolution of a species to take place a change in the gene frequency has to take place.

Energy Efficiency of Photosynthesis

Words: 1146 Pages: 4 4152

Photosynthesis is the process in which plants use the energy from the sunlight to make glucose (a type of sugar), which they then use as food. The equation for photosynthesis is: 6CO2 (carbon dioxide) +6H2O (water) -->(Sunlight) C6H12O6 (glucose) +6O2 (oxygen). Plants, algae, and cyanobacteria are photosynthetic organisms. In plants and algae, light is absorbed by chlorophyll—a molecule present in the cytoplasmic organelle called the chloroplast. Chlorophyll has a porphyrin ring with a magnesium cofactor at its center. Plants have […]
