Immune System The immune system is a network of cells, tissues, and organs that work together to protect the body from infection. Although scientists have learned much about the immune system, they continue to study how the body targets invading microbes, infected cells, and tumors while ignoring healthy tissues.mmune System The immune system is a network of cells, tissues, and organs that work together to protect the body from infection.

A truffle is the fruiting body of an underground mushroom. Its spores are dispersed by fungivores, animals that eat fungi.Almost all truffles are found in close association with trees. There are hundreds of species of truffles that are big, but the fruiting body of some (mostly in the genus 'Tuber') are highly prized as a food.The 18th-century French gastronome Brillat-Savarin called these truffles the diamond of the kitchen.here are hundreds of species of truffles that are big, but the fruiting body of some (mostly in the genus 'Tuber') are highly prized as a food.

Harvesting Truffles. Considering the symbiotic nature of the truffle, it makes perfect sense that they grow during the season in which their associated trees grow. The truffle is a seasonal fungus with varying growth patterns depending on the variety of truffle and its native country.hen it comes to truffles many culinary experts only consider two kinds acceptable: the black truffle and the white. These two primary varieties, like all others, grow underground, but considering their unique symbiotic nature this is too simplistic an answer.
