Plant With The Normal Soil Temperature
1,378 wordsABSTRACT The purpose of this experiment was to determine whether seedlings of the same kind will sprout faster under different controlled temperatures. The three controlled temperatures were 32^0, 20^0, and 5^0 degrees Celsius. The hypothesis will prove that the plant in the normal temperature range will sprout faster than the plants in the higher or lower temperatures. The procedure that was followed to support my hypothesis was to observe six germinating seeds in six separate pots. Two pots ea...

Seed Of Many Plants
9,139 wordsThe Basics. Sunlight plays a much larger role in our sustenance than we may expect: all the food we eat and all the fossil fuel we use is a product of photosynthesis, which is the process that converts energy in sunlight to chemical forms of energy that can be used by biological systems. Photosynthesis is carried out by many different organisms, ranging from plants to bacteria (Figure 1). The best known form of photosynthesis is the one carried out by higher plants and algae, as well as by cyano...

Biological Control Of Purple Loosestrife
3,265 wordsPurple Loosestrife The scene is breathtakingly beautiful, a thick brush of purple flowers blankets Canada's wetlands. This blanket silences the expected sounds of the wetland environment, birds chirping, ducks splashing, insects buzzing and animals thriving. This unnatural silence is disturbing, the favourite flowers that used to litter this landscape are no longer visible, the water that used to ripple continuously is perfectly still. The wetland is dead, except for this overpowering, hardy pur...

Post Fires Plant Succession
840 wordsSuccession is defined as a directional change in community composition and structure over time (Gurevitch et al, 2002). Succession is either primary or secondary. In primary succession plants grow and colonize earth for the first time. In secondary succession plants inhabit and colonize earth that was once inhabited by plants life. A wildfire is one example of secondary succession. When a disturbance in the environment occurs, such as a wildfire, either part or all of the community is destroyed....

Biomass And Stem Length Of Helianthus Plants
1,333 wordsEffect of Intra specific Competition on the Biomass and Height of Helianthus AnnuusAbstract: The purpose of this experiment was to study the biomass and stem length of Helianthus plants growing in an intra specific competitive environment compared to Helianthus growing in an isolated environment. I hypothesized that increased competition would limit the amount of nutrition available to each plant and thus effect the growth potential. A total of 24 plants, 6 to each pot were grown for ten weeks u...

Parts Of The Plant
795 wordsPlants have two different ways to reproduce. The first one is vegetative reproduction. With this type all the plants that have the same parent have the same genetic make-up. This also lets plants pass adaptations on that they have attained over the years. Plants with good genetic make-up usually spread quickly and take over an area. An example of this would be the dandelion. These plants can sprout from any part of the plant. An example of this is the potato, farmers will pick the potatoes and c...

Short Offspring And One Tall Plant
635 wordsGregor Mendel was born in Heinzendorff in 1822 and died in 1884. Ever since Mendel was a boy he was very interested in science. Whenever his friends would come back from school they would tell Mendel what they studied and he would be so excited. Mendel was so interested about what his friends told him that he begged his father to let him study. This meant a great sacrifice to his father he because owned a small farm. Needless to say, he sent his young son Gregor, who was only eleven to school. A...

Increasing Mortality Rate In Plants As Density
943 wordsINTRA SPECIFIC COMPETI ON: THE RESPONSE OF THE SUNFLOWER (genus HELIANTHUS) TO INCREASING DENSITY. INTRODUCTION All species, including plants, are impacted by density. Plants, of course, cannot leave their habitat as animals can, so they tend to respond in different ways to density. As populations grow more dense, they compete for resources such as food and space and are more prone to disease. Less dense populations are more susceptible to predation pressure. It is hypothesized that as plants in...

Germination Of A Seed
347 wordsProblem: How does the amount of light affect the growth rate of a seed? Literature Search: This experiment is only trying to verify the answer since this question has been proven before. Others have also proven that seeds germinate at the same rate at the early stages no matter how much or how little sunlight there is. Once the radicle brakes trough and the plant starts to use photosynthesis to produce energy and grow. Since sunlight is needed in photosynthesis, the plant with more sunlight star...

Highest Mean Number Of Seed Removal
1,416 wordsAbstract Why do seeds disperse to form new plants? If the seeds simply fell and grew beneath the parent plants they would be too overcrowded and would be starved of nutrients. So it is important that the seeds are dispersed over a wide area where they stand a better chance of finding the right condition to grow. In this experiment I predicted that the red color of jello would have the highest mean number of seeds removed from the aluminum tin pan. Also, between site 1 and site 2 of jello set out...

Smooth Seeds And One Plant
2,115 wordsMendel brought considerable insight to his studies. One of the most important decisions he made was to work in a system that was genetically simple as possible. His use of pure-breeding strains of pea plants is indicative of his quest for this simplicity". Mendel used pea plants in his experiments because they were cheap, available, easy to grow, and most importantly, genetically simple. He made these choices out of common sense, to make observation and research easier to accomplish, which is ne...

4 Leaves Per Plant
1,734 wordsEXCITING PLANT STUDY LUPINS AIM: To investigate the effect that different concentrations of Rhizobia has on the growth rate of the Lupin, Lupinus arboreus. HYPOTHESIS: I think that as the concentration of Rhizobia increases the growth rate of the Lupin will also increase. RATIONALE: The Lupin is usually in the early to middle stages of a succession as it is able to grow in poor quality soils, because of this it helps to stabilise the soil and provides shelter for the growth of other species. Lup...
