The effects of wind on plants depend on the species of the plant. Wind accelerates water loss through the leaves, so wind can result in the plant losing too much water. Transportation refers to the movement of water from inside the plant to the surrounding environment. Water from within the plant exits the plant through stomata, tiny pores in the leaves and enters the atmosphere. Wind accelerates the process of water leaving the plant. In certain habitats where strong winds are common, plants have adapted by evolving structures that minimize water loss. Pine trees, spruce, and other conifers have developed needle like leaves that reduce water loss, while cactus have developed spines that break up the wind?s force. Yet wind plays an important role in pollination by dispersing seeds and strengthening the stems of plants so they become more resistant to the elements.
- Two small to medium-sized potted plants of the same species and similar heights
- Electric fan (optional)
- Place the two plants in an area, indoor or outdoor, where they will receive the same amount of light.
- While conducting the experiment, make sure each plant is given the same amount of water and attention. All conditions should be approximately the same except for the control variable, namely the wind.
- Measure the height of the plants and take a photograph of each plant so that you have a record of its overall appearance.
- Place a fan so it faces one of the plants from approximately six feet away (adjust the fan or plant so that the other plant is not affected). Let the fan run on low for three hours a day for three to four weeks.
- At the end of the experiment, measure both plants. Compare the plants current appearance with the photographs taken earlier.
- Observe any changes that occurred in the plants.
