Introduction: Plant growth occurs throughout its life in a process known as indeterminate growth. This type of growth is capable because of the apical meristem and the lateral meristem. Meristem refers to a specialized section of plant tissue characterized by cell division and growth. Much of the mature plant ’s growth is provided by meristems in nature. And typically‚ Apical meristems found at the tips of stems and roots while lateral‚ or secondary‚ meristems found just under the surface along

Introduction For the past 30 years Scientist have searched desperately for the answer to salt toleration within plants. The damaging effects of salt accumulation in agricultural soils have influenced both ancient and modern day civilizations alike. Worldwide‚ an estimated 24.7 million acres of once agriculturally productive land are being lost annually due to irrigation-induced salinity‚ according to the U.S. Department of Agriculture. Thus‚ crop production is limited by salinity on 40% of

INTRODUCTION The echinoderm class Holothuroidea consists of sea cucumbers‚ which can be described as worm-like organisms with elongated‚ soft bodies. Like most echinoderms‚ holothuroids have 5 rows of tube feet along their bodies. These tube feet aid the animal in attachment‚ locomotion and respiration (Pearse et al. 1987). Within the class Holothuroidea‚ there are about 1250 species‚ and these are distributed among 200 genera (Smiley et al. 1991). There is much variety among the habitats in which sea cucumbers

Experimenting with Plant Growth Team Rocket Science Introduction: The purpose of the experiment was to establish whether the concentration of Schultz fertilizer that was added to the radish seeds effects the speed of growth during the six-week time frame of the study. The major variables with this study are proficient communications among the team‚ the seeds‚ soil‚ water concentration‚ fertilizer‚ light exposure‚ temperature of the room‚ consistency of following watering (watering the plant same time every

determine the factors that influences the rate of water loss from a plant through transpiration Introduction: Most of the water a plant absorbs is not used for a plant’s daily functioning. It is instead lost through transpiration‚ the evaporation of water through the leaf surface and stomata‚ and through guttation‚ which is the loss of water from the vascular tissues in the margins of leaves. There are three levels of transport in plants: uptake and release of water and solutes by individual cells‚

Bioterrorism-Disaster Concepts in community and public health November 29‚ 2010 Bioterrorism-Disaster Summary of Teaching Plan: The goal of teaching bioterrorism to the class is to educate them about the different/rare diseases that can spread through animals and nature. The goal of teaching disaster is to educate them about the two different types of disaster‚ how to prepare for any disaster‚ and to show an example of a disaster that happened. Both of these goals will be reached by presenting a power
