The types of organisms growing or living in the soil greatly influence the soil's physical and chemical characteristics. In fact, for mature soils in many parts of the world, the predominant type of natural vegetation is considered the most important direct influence on soil characteristics. For ...
Some types of organisms originated through endosymbiosis, the engulfing of one organism by another so that a part of the former becomes a functioning part of the latter . An unusual nucleomorph, a structure that contains DNA and resembles a cell nucleus, has been discovered within a plant known...
2.The discovery of evidence that plant diseases are caused by microscopic organisms was contemporary to discoveries substantiating the theory that infectious animal diseases are caused by microbes. In 1878, fire blight, a disease of pears and apples, was determined to be caused by a bacterium, a ...

This is the ultimate explanation of the meaning of human existence! The meaning and criteria for success vary among different types of organisms. Single-celled organisms pursue reproductive quantity, while social animals strive for collective influence. Most animals use desire and pleasure as survival...
Kant's conception of organisms as natural purposes raises a challenge to the adequacy of mechanistic explanation in biology. Certain features of organisms appear to be inexplicable by appeal to mechanical law alone. Some biological phenomena, it seems, can only be accounted for teleologically. Contem...
