ROOTS * is an organ of a plant that typically lies below the surface of the soil. * a part of a plant body that bears no leaves‚ and therefore also lacks of nodes. * is the beginning of the vascular system pipeline that moves water and minerals from the soil up to the leaves and fruits. FUNCTIONS OF ROOTS: * Underground (usually) * Anchor the plant in the soil * Absorb water and nutrients * Conduct water and nutrients * Food Storage ROOT SYSTEM: 1. Tap root system

morning Today we will tell u about the transportation of water and minerals in plants. The plants absorb water and minerals from the ground through roots. These nutrients are transported to various parts of the plant like stem‚ leaves and flowers. The phenomenon of upward movement of water and minerals is called ascent of sap. Only a small quantity of water is used up in metabolic process and growth of the plant. The plants require water and mineral salts for making food by process of photosynthesis

THE EFFECT OF LIGHT INTENSITY DURING PLANT GROWTH ON THE SIZE OF STOMATA IN DICOT LEAVES Christina Durgan Nicole Romero Vanessa Chilunda Biology 101‚ Thursday 1:15pm Claire Burkum 5 December‚ 2013 1. The hypothesis of this study is that the size of the stomata on the dicot leaves exposed to higher light intensity will be smaller compared to the size of the stomata on the dicot leaves exposed to lower light intensity. This is because at higher light intensity there is an increase in environmental

Introduction Submerged aquatic vegetation (SAV) are plants that have adapted to live within aquatic environments (DNR 2011). SAV are able to float in the water and move with the currents because they contain specialized cells called aerenchyma that provide buoyancy and they lack the more rigid structures of most terrestrial plants (DNR 2011). Many different species of SAV are found throughout estuarine waters worldwide and there are seventeen species of SAV that are commonly found throughout

common type being vascular dementia 10-30%.” Vascular dementia is a disease that mirrors the symptoms of Alzheimer’s disease. However‚ vascular dementia is caused by a lack of oxygen that travels to the brain‚ which in turn results in memory loss. Those who suffer from vascular dementia are usually older individuals. Age is one of the biggest risk factors with vascular dementia. According to Peters (2012)‚ blood pressure‚ smoking‚ and alcohol have all played roles in causes of vascular dementia. As most
