The vascular tissue contains xylem cells, which are important for transpiration because the xylem cells allow the water to move against gravity to reach the uppermost leaves in the plant. The stomata are important for transpiration because they contain guard cells that control the amount of water that can enter and exit the plant. This is important because in hot conditions the guard cells close up and becomes turgid to prevent water loss because they cannot afford to lose too much water to the environment and in cold conditions the guard cells open up and lose water so they become flaccid. 4 ...

Bioinformatics can be defined as "The mathematical, statistical and computing methods that aim to solve biological problems using DNA and amino acid sequences and related information.9" A fundamental principal of biology is that the genes within each DNA cell are encoded with RNA, which produces the proteins that regulate all of the biological processes within an organism. The human body is made up of an estimated 1012 cells, each of which contains 23 pairs of chromosomes that are comprised of approximately 20,000 - 40,000 genes which in turn contain some 3 billion pairs of DNA bases....
