DEVELOPMENT OF THE INTERNODE LENGTH OF VIGNA RADIATA WHEN GROWN UNDER DIFFERENT LIGHT INTENSITIES ABSTRACT Throughout their growth plants exhibit varying ways to adapt and change depending on their circumstances‚ with changes in the amount of available light being a major factor in plant growth. The aim of the study was to determine whether there are significant differences in the growth patterns of Vigna radiata when grown under varying light intensities. Plants were grown in two different light

Flowering plants grow in a wide variety of habitats and environments. They can go from germination of a seed to a mature plant producing new seeds in as little as a month or as long as 150 years. Plants that complete their life cycle in a single season are called annuals; while biennials take two years; and perennials may take several to many years to go from germinated seed to producing new seeds. Fruits and Seeds The taste of a fruit depends on the combinations present in it. Normally

Ferm Life Cycle Introduction: This essay will discuss the fern life cycle as taught in biology lab. The essay will cover the basic process which we used to grow a fern. I will discuss the methods and the results of the lab exercise. Finally‚ I will discuss the evidence of the methods and results that were obtained . Methods and Results: To begin our experiment we obtained a petri dish from our lab instructor which contained fern spores and the food they needed to survive. We then look at

FACTORS INFLUENCING HABITAT GEOGRAPGHY 1010 GEO 1010 TOPIC: FACTORS THAT INFLUENCE HABITAT What is habitat? What environmental factors limit the distribution of habitat? How do organisms interact with one another? How do habitat communities change with time if left undisturbed? Where do species come from? How do they change and evolve? These are question that will be discussed later. There are several factors that influence habitat: A habitat is

Population Ecology: Clover Distribution and Density Method This lab consisted of the use of various materials. We used four orange flags in order to mark a 30x15m sampling area in which we collected our data from. To measure out the area‚ we used a thirty meter measuring tape and to determine the density (plants per meter squared) of clovers in the lawn‚ we calculated the total area of the plot (30x15meters squared). For this lab‚ a frisbee was used with the area of .053 meters squared as the

WANTED Dead not Alive: Cogongrass (Imperata cylindrica) has become a major problem for landowners‚ land managers‚ foresters‚ and governmental agencies since its introduction into Alabama. Known to many as japgrass‚ cogongrass was accidentally introduced into Alabama near Grand Bay about 1911 as seed in packing materials from Japan (4). Purposeful introductions soon followed in other areas of Alabama‚ Mississippi‚ and Florida‚ with the primary intent for forage production (1‚4). Horticultural

Role of mycorrhizas in the mineral nutrition of host plants Mycorrhizas are very important in the uptake of nutrients such as P‚ N‚ K‚ Cu‚ Zn and Ca by plants especially in soils low in these nutrients. Since P is the most limiting nutrient in tropical soils‚ mycorrhizas are vital for improving P nutrition particularly for cultivated plants. External hyphae can absorb and translocate P to the host from soil outside the root depletion zone. The thin mycorrhizal hyphae (2-4 μm in diameter) are able

Alkaline soil is referred to by some gardeners as”sweet soil”. The pH level of alkaline soil is above 7‚ and it usually contains a great deal of sodium‚calcium and magnesium. (1) Alkaline soil occurs in areas with high limestone content‚ easy souble phosphorus and calcium binding‚ formation of insouble calcium salts of phosphorus‚ reducing the effectiveness of phosphorus. Also‚ in calcareous soils‚ boron‚ manganese‚ molydenum‚ zinc‚ iron greatly reduces the effectiveness of the crop often feel inadequate

INTRODUCTION Major of us was seemingly misinformed or not knowledgeable enough about this certain topic‚ The Nuclear Energy and its capabilities. Nuclear energy is a clean‚ safe‚ reliable‚ independent and competitive energy source. Moreover ‘this’ energy can be of great help with reducing and preventing air pollution that can lead and contribute to the greenhouse effect by replacing a significant part of the fossil fuels. Also‚ besides from the fact that it can be the source of our electricity‚
