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. The aftermath of the wildfire leaves a barren landscape open to new growth‚ vegetation‚ and re-colonization of plant species (Gurevitch et al‚ 2002)

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:
