A tree is a plant. Trees are perennial plants that use photosynthesis to make their own food like other plants. They have woody stems and trunks and tend to live for many years.


Some of the reasons that trees are so important to the environment include the fact that they clean the air, clean the soil, produce oxygen and slow storm water runoff, according to About.com. Trees also control noise pollution, provide shade for protection from the sun and much more.


Plants provide food to people and animals, regulate the water cycle, create oxygen and provide a habitat for other species. Without plants, life on Earth would not be sustainable for most species, including humans.


When growing a jade plant from a cutting, cut a healthy branch that is 3 to 4 inches long off a jade plant, and leave the cutting to dry for a week or two. Mix vermiculite and soil in equal amounts to make the potting mixture, and place the dried cutting in the mixture. You can use perlite instead o


Plants normally use water in various processes including photosynthesis, transpiration, support system and nutrient distribution. Without a sufficient supply of water, plants may not develop well and some may even die.


Trees benefit the environment by helping to keep it free from toxins, supplying life on Earth with nutrients and combating the negative effects of harmful gases that exist in it. Trees allow consumers to save energy, further helping to reduce the impact of the overuse of resources.


Plants are important to animals as animals rely on them for food, oxygen and habitat maintenance. Without plants, animals would not be able to meet their basic needs. As much as animals depend on plants, plants depend on animals too.


Plants are green because of a pigment called chlorophyll. Chlorophyll absorbs all colors of visible light except for green, which is reflected. Thus, the reflection of the green part of visible light is what causes plants to look green.


Leaves are important because they are the primary source of photosynthesis, which is how plants feed themselves. Photosynthesis is the process of turning light energy into sugars, which plants need to survive, so leaves are very important to a plant's overall health and survival.


Soil is important to plants because it stores nutrients and serves as a medium for growth. It is an anchor for roots and also holds water needed by plants for moisture. Soil contains the air, water and food that provides a suitable place for plants to grow.
