3. Explain how the products of photosynthesis are transported‚ partitioned and allocated during plant growth and reproduction. Photosynthesis has been the focus of much attention than any other physiological process in flora physiology. Photosynthesis is a complex plant metabolic process‚ similar to respiration and fermentation‚ in which a plant can synthesize organic matter using light and chlorophyll. According to Kirk 1994: Photosynthesis is a complex physic-chemical process that is the central

INTRODUCTION I. Have you ever wondered how the process of sexual reproduction begins in multi-cellular organisms such as ourselves? II. It all begins through a cell division process known as meiosis. III. I am currently a biology major at CSU-Pueblo looking to pursue a degree in wildlife biology. IV. During the process of meiosis‚ diploid cells split in half‚ forming four haploid cells‚ which each have a single set of chromosomes. These cells are called either gametes or sex cells. Female gametes

had a police officer tell you to do something and you did it without even considering otherwise? From an early age‚ we are conditioned to respond immediately when an authority figure gives us an order. For this reason‚ I chose an article about a reproduction of the Milgram study that took place in 1963 and established that people will go to extreme lengths to obey authority. The Holocaust was the motivation behind Milgram’s study and we are all knowledgeable of the atrocities ordered by Hitler (Simplepsychology

Parthenogenesis vs. Sexual Reproduction Jorge Pablo Velasco Borda Introduction: Parthenogenesis is a type of reproduction in which the sperm does not fertilized the ovum. In parthenogenesis some chemical agents fertilize the ovum most of times because the female does not have a male to have sex with. That’s the case of Flora a Komodo dragon that live at the Chester Zoo in England (Chiang. M). Flora gave birth to seven babies without having a male. Sexual reproduction is when a sperm fertilize
