Hybridization 11/29/2022 Making a new organism out of two existing organisms Gregory Mendall, who was the  founder of Mendalls crosses also Hybridization which is where you take two true breeding organisms and cross them. This why you can a patch of red roses and white roses and get pink one's "Hybridization, as related to genomics, is the process in which two complementary single-stranded DNA and/or RNA molecules bond together to form a double-stranded molecule."(Sidransky 1). This quote from NIH further explains the process and what hybridization is. This is how farms and other planters make certain colors or unique crosses of plants. This process is extremely popular in making new species. that aren't native to mother nature. "Hybridization is widespread across the tree of life, spanning both ancient and recent timescales and a broad range of divergence levels between taxa"(Moran 2021). This quote from life gives evidence that hybridization doesn't ju

 Plants forever changing 11/6/2022 The world is changing because of Mother Nature and human interference. In the beginning all of the plants were in the ocean, then slowly made the transition to land by developing four key parts. First the cuticle which prevented them from drying out. Then they developed a vascular system which dug deep in the ground and helped support the plant and provided water. After that came the seed which was part of the reproductive system. Finally the flower which was a carrier for the seed. "Plant adaptations to life on land include the development of many structures — a water-repellent cuticle, stomata to regulate water evaporation, specialized cells to provide rigid support against gravity, specialized structures to collect sunlight, alternation of haploid and diploid generations, sexual organs, a multicellular embryo protected by parental tissue, a vascular transport system, and  rhizoids , roots and root hairs essential for the absorption of nutrient
