What affect does fertilizer have on the rate of growth in plants over a certain period of time? When tested‚ there is no affect on the growth of plants from a change of an environmental factor‚ such as an exposure to fertilizer. By changing the independent variable (whether or not the plant was planted with fertilizer)‚ you are testing to see how the dependent variable would change (the growth of plants). In order to assure that there is no experimental error‚ a control must be kept to produce the

Photosynthesis: Plant cells vs. Solar Cells Chevon Allen 01/23/2010 SCI-115 Professor Garcia Photosynthesis and the semiconductor-based solar cell are very similar process with different ways of reaching the same goal. In photosynthesis‚ plant cells harness the solar energy of the sun with carbon dioxide to transform water molecules into hydrogen‚ oxygen‚ and electrons. Just like photosynthesis‚ Semi conductor based solar cells harness the solar energy of the sun for the same purposes

of caffeine on plant growth | Description This science fair project was performed to find out the effect on plant growth of adding caffeine to the soil. The experiment was done by using mung bean plants and watering them daily with water‚ water mixed with caffeine and with a coffee mixture. Hypothesis The mung beans watered using the coffee mixture will grow the fastest. Overview Caffeine and plant growth The effect of adding caffeine to the soil and its effect on plant growth is a subject

The Affect of Different Colored Light on Plant Growth Puprose: Just as we are happier and healthier when we receive adequate sunlight‚ so are the plants and vegetation that we grow. Sunlight‚ or other means of artificial lighting is essential to help a plant grow into maturity. It is also necessary in aiding the plant to get the nutrients it requires to mature into a strong healthy plant. The process of the sun or other light helping to feed the plant is called photosynthesis. The light acts

-How plants get liquid and minerals- Flowers absorb liquid through their roots‚ which are attached to xylem vessels. Xylem vessels are tubes that can expand through several feet of tissue and be .7mm in diameter. Their walls are thickened with cellulose deposits. Xylem bring water up to the leaves and petals of the plant. Even without contact with the roots‚ the xylem can still absorb water. Because of this‚ a cut flower usually doesn’t die for a couple days (as long as it is placed in water of

Amount of Water Effects Plant Growth By Dennis Marchuk Turner Ashby High School Grade 10 March 23‚ 2013 The purpose of this project was to determine how much the amount of water effected plant growth. This had been accomplished by taking three groups of plants and placing them next to one another. Each group contains two plants. Each one would be watered with a different amount of water. They would then be measured how much they grew. The growth of the three plants was compared. Hypothesis:

Botany Essay Questions 1. Pollination is a crucial process of how plants reproduce‚ in which the male sex cell of the flower‚ pollen‚ is transferred from the stamen to the carpel‚ or more specifically‚ from the anther to the stigma. Pollen grains are completely different and unique for each flower‚ they carry the male and female genetic information and it is split exactly 50/50. The transfer is carried out by pollinators‚ which include bees‚ wasps‚ flies‚ butterflies‚ moths‚ several species
