Cell wall for higher growth rates in diatoms. In brown algae, phlorotannins may be a constituent of the cell walls. The group Oomycetes, also known as water molds, are saprotrophic plant pathogens like fungi. Until recently they were widely believed to be fungi, but structural and molecular evidence has led to their reclassification as heterokonts, related to autotrophic brown algae and diatoms. Unlike fungi, oomycetes typically possess cell walls of cellulose and glucans rather than chitin, although some genera (such as "Achlya" and "Saprolegnia") do have chitin in their walls. The fraction of cellulose in the walls is no more than 4
Pharmacy school must study six years to become pharmacists. The best school of pharmacy is at Universidad de Chile , in Santiago de Chile. Chilean pharmacists are prepared not only to dispense and be able to work at clinical and communitary pharmacies, but in Pharmaceutical, Food and Cosmetic industry at every level, including drug development (a Degree is needed here), manufacturing, management, marketing, etc., due to the very strong scientific preparation they receive, including engineering and pharmaceutical technology topics. The official title for pharmacists in Chile is Químico Farmacéutico (Pharmaceutical Chemist), and their degree is Licenciado en Ciencias Químicas y farmacéuticas (Bachelor
