PPT-Viruses Smallest unicellular organisms that are obligate intracellular.

Viruses are the most primitive microorganisms infecting man General properties Obligate intracellular Possess either DNA deoxyribonucleic acid or RNA ribonucleic acid but never both Smaller than bacteria can be passed through the bacterial filters. As living things are constantly being investigated, new attributes are revealed that affect how organisms are placed in a standard classification system.. . . Classifying Living Things. Carl Linnaeus was a . Multicellular. Which is better?. Questions to Consider. How quickly can it reproduce?. How specialized can it be?. How large can it grow?. How long does it take to develop?. How long can it live?. How quickly can it adapt and evolve?. Turn and Talk. What is a cell?. What is an organism?. What is a single-celled organism?. What is a multicellular organism?. Cell Video. Single-Celled Organisms. Organisms made up of only one cell. . EQ: Why are viruses considered to be non-
living?. Characteristics:. *Nonliving particles made of . nucleic acid. and a . protein coat . enlosed in a . capsid. shell... *In order to reproduce, all viruses must have a . 7. th. Grade Science. P.S. DuPont Middle School. The History of Classification. In the 1700’s, Linnaeus separated all life into 2 Kingdoms: Plants and Animals.. More kingdoms added as knowledge of the diversity of organisms increased.. Biology: Science of Life What do Biologists do? Study past, present and future life Interactions, structures , functions Solve biological problems Agriculture Disease Conservation/Remediation to maintain diversity of life arboviruses. ) are viruses that can be transmitted to man by arthropod vectors. . Arboviruses. belong to three families:. Togaviruses. . Bunyaviruses. e.g. . Sandfly. Fever. .. Flaviviruses. e.g. Yellow Fever, dengue, Japanese Encephalitis. . . The process of transfer of virus into host is referred as . TRANSMISSION. and this is an important step in the life cycle of viruses.. Person to person infections are said to be . HORIZONTAL. .

Glue in your skeleton notes. Fitua. Al-. Saedi. Department of Clinical Laboratory Science. College of Pharmacy. Medical Microbiology. Microbiology . Is . the study of Microorganisms, a large and diverse group of microscopic organisms existing as single cells or clusters. Micro- organisms include some eukaryotes and prokaryotes, viruses, . Standards. GSE S7L1: Obtain, evaluate, and communicate information to investigate the diversity of living organisms and how they can be compared scientifically.. GSE 7L1b: Evaluate historical models of how organisms were classified based on physical characteristics how that led to the six-kingdom system (currently archaea, bacteria, protists, fungi, plants and animals). ®. Cytokines are rapidly secreted upon expression which results in. low / not detectable intracellular concentrations.. The use of secretion inhibitors allows for intracellular accumulation of cytokines:. Your Objective. 1. You will understand that . organisms. are composed of one or more . cells. . . 2. You will . identify the basic characteristics of organisms: . unicellular organisms. multicellular organisms. Multicellular.  organisms, or organisms that are made up of many cells..  . “multi,” meaning . many . Examples of Multicellular organisms: All animals, plants, most fungi. Cells are very small, so you usually need a microscope to see.
