There are two main methods of reproduction: sexual and asexual. Sexual reproduction requires two genetically distinct gametes to combine, and usually it involves two members of a species (though not always).

The filtration process is simple, but effective. The basic principle is that there are passages through the filter that are wide enough for water droplets to pass through, but too narrow for pathogens. Tests with the deadly E-coli bacterium have seen the filters remove 96.4 to 99.8 per cent ...
Plasmodesmata are small channels that connect plant cells. They facilitate interactions between the cytoplasm of adjacent cells through the the transfer of small and large molecules. They are an important route for cell-cell communication. Plants are multicellular organisms; they are made of hundreds ...
