Also, data showed that pea seeds had higher, more successful germination rates than bean seeds in cool temperatures. Overall, the hypothesis was supported by the data found in through the experiment and pea seeds should be grown in cooler temperatures, whereas bean seeds should be grown in warmer temperatures. Introduction: Seed propagation involves either the natural or assisted placement of seeds in favorable conditions to promote germination. By definition, germination is “the process by which a dormant seed begins to sprout and grow into a seedling under the right growing conditions” (www.biology-online.org). The purpose of this experiment was to investigate on which seeds have the highest germination rate in varying climatic temperatures.
Bean Sprouts Experiment Lab Report Research Question (Aim): To determine whether the different amounts of water affect seed germination. Hypothesis: I hypothesize that the largest number of seed germination will occur in the petri dish given 10ml of water. I believe that because, if the plant receives too little water, it will cause the plants to wilt. The plants wilt as they lose water quicker than they gain it from the soil. If the plant collects too much water, it will cause the roots to rot, resulting in the plants not being able to receive enough oxygen from the soil.
The hypothesis is that the clover plants will not grow as much in the shade as they will in the sun. This is testable as quadrants from sunny areas and shaded areas can be looked at and the findings of those quadrants recorded and the data compared. The independent variable is the amount of sunlight a quadrant gets and the dependent variable is the amount of clover plants and their coverage inside the quadrant. The size of the quadrants stays constant throughout the experiment and the size of the paper used to find the clover coverage stays constant at 10cm2 throughout the experiment. If the results show that sunny quadrants have more clovers in them the hypothesis is supported but if the results show shaded areas have more clovers the hypothesis is not supported.
Brief Explanation This experiment will test the effect of caffeine on the growth of mung bean plants. By testing this, I can also prove the effect of caffeine on all other organisms. The experiment could go either way: the plants with caffeine could grow more or they could stop growing once I add the caffeine in to the equation. * Independent and Dependent Variables * The independent variables are the watering solutions which are water, caffeine solution, and coffee mixture. The constants are the size of the pot, the concentration of caffeine and coffee, the amount of sunlight, the temperature of the environment (which will remain at room temperature) and the amount of water added daily.
Photosynthesis is performed by various life forms, however, the best organisms’ for this process is by cyanobacteria, algae and higher plants (Vermaas, 2013). The end result of the Photosynthesis process is the storage of energy in sugar bonds. Vegetation requires energy, H2O and CO2 in order to create sugar. Photosynthesis occurs in a plant’s chloroplasts, specifically using the green pigment that captures light energy; which is why it primarily takes place in the plant’s leaves. The veins in a leaf transport nutrients and water where they are needed and chloroplasts are in a plant’s mesophyll cells, which is where photosynthesis takes place.
Light energy has a major role in this process. Without this energy, photosynthesis is not possible to occur. In this experiment, I will find out the correlation between light energy, rate of carbon dioxide, and rate of photosynthesis. I will place the beaker containing the plant in three different distances and measure the resulting bubbles oxygen produced. The number bubbles produced shows the affect of light energy to the rate of photosynthesis.
That’s why Jamaica and the Barbados were huge in growing sugar. The sugar trade was motivated by land and climate, consumer demand and the economy. First of all, the sugar trade was impelled by the land and climate. Document 2 shows that sugar cane needed plenty of rainfall, at least 80 to 90 inches per year. Besides that, sugar cane needed to grow in a temperature range between 68-90 degrees with soil that was alluvial or volcanic with a sand silt and clay mix.
Houle (2007) found that trees flowered 2-6 days earlier in 2000 than they did in 1900, indicating that global warming is impacting the phenology of plants. This can affect plants by altering their growing seasons, which may have unknown impacts on the plants. Increased temperatures linked to global warming have also been associated with decreased frost resistance, which can lead to an increased amount of damage to trees’ buds (Bannister et al. 2005). Studying these factors is important because it will allow us to understand and predict the changes that will occur due to the evolving climate and
| | The FACTS-I experiment is testing how elevated CO2 influences tree growth, carbon concentration in soils, and other factors over a ten-year period. | Greenhouse Effect | The greenhouse effect is caused by atmospheric CO2 but is necessary to keep the surface of the Earth at a habitable temperature. | | Increased levels of atmospheric CO2 could cause global warming and significant climatic change. | | Life on Earth is protected from dangerous radiation by a protective layer or ozone molecules present in the atmosphere.
The ozone layer which is our protector from the sun is impacted with the increase of burning fossil fuel such as oil, coal, and natural gas which increases atmospheric carbon dioxide. For all plant growth, phosphorus is an important mineral that is used as fertilizers that assist with plant blooming and production. This key element that plants use is needed for animals and humans and it begins with rain runoff that breaks down rocks which release phosphorus into the ground and eventually into the water supply. Humans’ impact the phosphorus cycle by the over use of manmade fertilizers that eventually returns to the earth and find their way into the ocean. With water pollution ocean life becomes tainted with over fertilization that can lead to death of plant and animal life.
