Structure of the Stem The internal structure of the stem is usually more complex than the other plant organs for it performs and provides various functions. These functions are: * For mechanical support * For conduction of water * For conduction and storage of manufactured food * For continuous growth of the stem in thickness These functions are centered at the fibro vascular system that is composed of two major tissues‚ the xylem and the phloem. Internal Parts of Woody Stems 1. Protective

Follicle Stem Cell Niche and the Function of the Rac1 protein within the niche. Abstract: An adult stem cell’s niche is responsible for the preservation of the stem cell’s undifferentiated state through either intrinsic or extrinsic expression of specific proteins (Scadden‚ 2006). Situated in the bulge of the hair follicle‚ hair follicle stem cells (HFSC) are quiescent in nature and are responsible for not only its self renewal but also in the production of rapidly proliferating cells. These cells

I have always had a passion for the STEM field. Ever since I was a child I have been exposed to biomedical engineering from a young age‚ have always loved my science and classes‚ and have had experiences that have introduced me to different fields of STEM. So far I have taken ten STEM classes in Highschool. and my favorite was Biology. I remember loving every second of every lab we did and excelled in them. I have taken 4 lab based courses Pre-AP Biology‚ Pre-AP chemistry‚ AP physics and AP Chemistry

Embryonic Stem Cell Research: How does it affect you? Embryonic stem cell research is widely controversial in the scientific world. Issues on the ethics of Embryonic Stem (ES) cell research have created pandemonium in our society. The different views on this subject are well researched and supportive. The facts presented have the capability to support or possibly change the public’s perspective. This case study is based on facts and concerns that much of the research done on embryonic stem cells

have a huge impact on the communication between cells. Cell communication is a crucial process necessary for cells to carry out various functions. Drugs such as Methylenedioxymethamphetamine (MDMA)‚ known as ecstasy‚ can create barriers or confusion to cells. Cell to cell communication carry messages from signaling cells to target cells. Usually a cell will bind with a target cell through a receptor protein in the plasma membrane of the target cell

Analysis of STEM fields Analysis of STEM fields 1. Introduction STEM is an acronym that referring to Science‚ Technology‚ Engineering‚ and Mathematics (Rotherham‚ 2011). What is STEM? The simple answer is that STEM means jobs. A complicated answer is that it is an educational key to a better U.S. economy; it addresses the growing disconnect between the skills that employers need in a rapidly increasing technological world and the lack of talent that the education
