Almeida Silvia Fernandes‚ Krisann Garrard. The effect of Lead Toxicity on Pollen germination. Received: 15th February 2012 Abstract: Pollen obtained from the Hibiscus rosa-sinensis‚ commonly known as the Hibiscus flower were exposed to different concentrations of Lead to understand the effect of heavy metal on pollen tube germination. Heavy metals such as Lead‚ have shown to decrease the pollen germination and inhibit pollen tube growth. There was a correlation observed between the concentration

The effect of food source (mung bean Vigna radiata vs. black-eyed pea Vigna unguiculata) on relative inhibition of acetylcholinerase due to malaoxon in bean beetle Callosobruchus maculatus Background and Hypotheses: Recent studies‚ most notably Gbaye et al. (2011‚ 2012)‚ have investigated the sensitivity of bean beetles in the genus Callosobruchus to organophosphate insecticides (OPs). Economically this is important work given that these beetles are pests that threaten agricultural yields

Florencia Rodriguez October 20‚ 2010 IB Biology SLII The effect of three different pH levels (4‚ 7‚ 10) on the rate of germination of spanish beans Research Question: What is the effect of three different pH levels (4‚ 7‚ 10) on the rate of germination of spanish beans? Independent Variable: The different pH levels in the water would be the independent variable in this lab. Three different pH levels were tested‚ 4‚ 7 and 10‚ both 4 and 10 were chosen because they are 3 pH levels away

BIOL 1401 General Biology Laboratory Seed Germination Exercise Introduction Seeds are produced by the more advanced plant groups that we will study this semester – Gymnosperms and Angiosperms‚ which are grouped as seeded-vascular plants. While we often take seeds for granted‚ they are remarkable in their physiologies and very diverse in their structure and germination requirements. Seed biology is actually a separate sub-discipline in botany‚ with direct significance to the study of plant ecology

Colleen Hamilton AP Lab 4: Determining the Rate of Cellular Respiration of Peas at Varying Temperatures and Stages of Germination I. Purpose and Intro The purpose of this lab is to determine the rate at which germinating peas respirate at varying temperatures and stages of germination. Cellular respiration is the set of metabolic reactions and processes that takes place in an organism’s cells in order to create ATP from sugar. It occurs in the mitochondria and comprises three stages: glycolysis

there was a significant difference between the internode lengths of V. radiata grown under the different light intensities‚ with the plants grown in normal light having shorter internode lengths than the plants grown in no light. It is clear that the rate of development of structural characteristics is significantly greater for plants grown in normal light intensities then those grown in no light as their features are underdeveloped. INTRODUCTION Unlike most animals once a plant has established

The Effect of Microwave Radiation on the Respiration Rate of Phaseolus vulgaris Aerobic Celluar Respiration is a process that is carried out by most living organisms. The process is a series of chemical reactions that occur within the mitochondrial matrix and cristae of eukaryotic cells. Following the anaerobic process of glycolysis‚ partially broken down sugar molecules enter the matrix of the mitochondria where they are further reduced by oxygen. In the process‚ a small amount of ATP is created
