soon as we crossed the river we walked along it to the hill. Great plants grew among the roots of the big trees and spread rosettes of green fans. When the wind blew the leaves were singing on the trees. The blotched fungi and moss extended through the roots of the trees. The fungi were different sizes and color. The moss was so soft‚ that if you lie on it you would feel a soft pillow under you. The honeysuckle was ripe on the bushes. Then I saw some man who was gathering something‚ perhaps some

health‚ welfare‚ food‚ and industrial products. Micro-organisms are microscopic organisms and can only be seen properly with the aid of a microscope. This includes viruses‚ microscopic fungi and bacteria. The human body is continuously handling various different micro-organisms on and in them‚ but mostly bacteria. Some fungi and other micro-organisms under normal circumstances in a healthy person is normally harmless‚ and can even be beneficial. One of these micro-organisms is known as the normal flora

parent. A more stringent definition is agamogenesis which is reproduction without the fusion of gametes. Asexual reproduction is the primary form of reproduction for single-celled organisms such as the archaea‚bacteria‚ and protists. Many plants and fungi reproduce asexually as well. While all prokaryotes reproduce asexually (without the formation and fusion of gametes)‚ mechanisms for lateral gene transfer such as conjugation‚ transformation and transduction are sometimes likened to sexual reproduction

Outbreak of fungal meningitis Disease outbreaks are one of the biggest concerns in the world‚ because they can happen out of nowhere and cause a lot of damage before being dealt with. The United States faced such an outbreak when a‚ supposedly safe‚ pain relief medication resulted in an outbreak of fungal meningitis. Fungal meningitis is a rare infection that occurs mostly in patients with compromised or suppressed immune systems; however‚ the epidural steroid injections used to treat inflammation

Cell: The cell is the basic structural‚ functional and biological unit of all known living organisms. Cells are the smallest unit of life that is classified as a living thing‚ and are often called the "building blocks of life". Discoverer: The cell was discovered by Robert Hooke in 1665. The cell theory‚ first developed in 1839 by Matthias Jakob Schleiden andTheodor Schwann‚ states that all organisms are composed of one or more cells‚ that all cells come from preexisting cells‚ that vital functions

in coal‚ oil and natural gas returns to the atmosphere when these fossil fuels are burnt and during natural combustion occurrences such as volcanic eruptions. Fossil Fuels such as coal are constructed when a living organism dies and decomposers‚ ie Fungi and microbes are unable to decompose it. After the organic material is untouched for millions of years‚ it eventually turns into fossil fuels. Petroleum‚ coal and natural gas Carbon is stored in fossil fuels until they are released from the ground
