Plant cell wall material is composed of three important constituents: cellulose, lignin, and hemicellulose. Lignin is particularly difficult to biodegrade, and reduces the bioavailability of the other cell wall constituents. A bit of knowledge about each of these constituents is helpful in understanding the vastly different rates that different plant materials decompose.

Why build a microscope? The following is a guide on how to build a stereoscopic microscope. This guide allows you to assemble, at a relatively low cost, an instrument that is useful for observing natural objects such as insects, plants, minerals, fossils and flowers.

Soil is one of our most precious natural resources, as it integrates all parts of the ecosystem. It provides a medium for plant growth so that we can have food, clothing, and other materials. Soil filters water, decomposes waste, stores heat, and exchanges gases. Soil is alive- it is the home to billions of micro- and macroscopic organisms. It is a material used for construction, medicine

The plant-like appearance of lichens hides their true identity. A lichen is not a single organism, but the result of a partnership (mutualistic symbiosis) between a fungus and an alga or cyanobacteria. Some lichens are formed of three or more partners. The body of a lichen consists of fungal filaments (hyphae) surrounding cells of green algae and/or blue-green cyanobacteria. The basis

The purpose of this experiment was to see what materials work the best in a sandbag for preventing a flood. Fine and coarse gravel, plant soil, and mulch are not usually put in sandbags to stop floods. Most people do not have a lot of sand that they can put in sandbags. That's why I'm doing this experiment, to see if fine and coarse gravel, soil, or mulch can have the same effect as sand.

The purpose of this experiment is to determine whether magnets have an effect on the growth of radish seedlings. I became interested in the study of the effect magnets, when I discovered that magnets could make you heal faster. Later I decided that that it would be a better idea to study the effect of magnets on plants to keep it a safe experiment.

Enzymes are very large and complex organic molecules that are synthesized by the cell to perform very specific functions. These biological catalysts are important because they speed up the rate of the reaction they catalyze that would otherwise be too slow to support life. Catalase is an enzyme present in the cells of plants, animals and aerobic (oxygen requiring) bacteria. It promotes

The purpose of this experiment was to determine how organic material affects the water absorbency of soil. The information gained from this experiment will aid gardeners by determining which organic material will benefit their plants the most.

The purpose of this experiment was to determine how different deicers affect the survival of radishes. The information gained from this experiment could be used by farmers and gardeners to help select, when needed, the deicer least harmful to their plants.
