It is a leaf that has evolved from a branch system and is characterized by branching veins. Cladophyll: Also called phylloclade, this is a flattened stem that looks like a leaf. Get to know some interesting stem cell research facts and…. Facultative Aerobe (Facultative Anaerobe): Organisms that use oxygen when available, however, can even live without it. Tissue: A tissue is an ensemble of cells featuring similar structure and performing a specific function.

It was the plants present in his backyard that inspired Gregor Johann Mendel to propose the first laws of genetic inheritance, that are studied even to this day. Abscisic Acid (ABA): A growth inhibiting hormone enabling perennial plants to tolerate stressful conditions by promoting dormancy, stomatal closure and inhibiting growth. Codon: Triplet of adjacent nucleotides in messenger RNA, which specify the amino acid to be incorporated into a protein. Endosymbiont Hypothesis: According to this hypothesis, mitochondria and plastids were free-living bacteria, which got incorporated into the cells. plural botanicals.
