PPT-An Introduction to Model Organisms

Krishanpal Karmodiya Template SlideShareAdhweat Gupta krishiiserpuneacin httpwwwiiserpuneacinkrish A model organism is a nonhuman species that is extensively studied to understand particular biological phenomena with the expectation that discoveries made in the organism model will provide insight into the workings of other organisms. A. Introduction – There are multiple criteria by which you can classify an organism. 1. Metabolic Activities (Carbon, Energy & Oxygen sources). A) Recall that microbes may vary in their carbon & energy sources. Kingdom Protista. A. Sometimes not considered a true kingdom because the organisms vary tremendously from one to another. The only universal characteristic among the group is that they are all eukaryotic.. Ecology. Ecology: The study of the relationship between organisms and their environment.. Example problems that ecology handles. How do humans affect the atmosphere and contribute to global warming? . Continuous spectrum which makes it difficult to place in distinct groups. Natural – evolutionary. Artificial - purposeful. Classification. Five Kingdoms:. Protoctists. Prokaryotes. Fungi. Plants. Animals. Bird, frog ,sea star, shark, sponge, squid, worm, jellyfish, clam, coral and other organisms. TRY and divide them into two main categories based on classification.. List the categories and divide them organisms into two groups. A. Introduction – There are multiple criteria by which you can classify an organism. 1. Metabolic Activities (Carbon, Energy & Oxygen sources). A) Recall that microbes may vary in their carbon & energy sources. LESSON 3. Unicellular Organisms. Organisms that consist of one cell. . They are also known as microorganisms. They also carry out all the life processes such as movement, response, respiration, digestion, excretion, reproduction, and growth. Biosphere: All life on earth and parts of earth in which life exists (land, water and atmosphere). Studying Our Living planet. Science of Ecology. Study of interactions of living things, their surroundings or environments. Needham theorized that if he took chicken broth and heated it, all living things in it would die. . After heating some broth, he let a flask cool and sit at a constant temperature.. . Result: Lots of microorganisms grew in flask. I. Biotic and . Abiotic. Factors. A. Biotic Factors-- all living things that inhabit an environment. 1. relationships with organisms of the same or different species. . B. . Abiotic. Factors: The nonliving environment. What is Ecology?. Ecology = . the study of . relationships. among living organisms and the interactions with their . environments. . . Ecologist = . a scientist who studies ecology . Perform tests in organisms’ environments. Biomedical Technology I. 3.03. GMO’s:. Also known as Transgenic Organisms. Are species that carry one or more genes from another species.. These have continued to improve since the 1970’s. Advantages:. 3.1.2 Micro-organisms. 3.1.3 Monera, e.g. Bacteria. Follow-Me – . iQuiz. Q. To which kingdom do bacteria belong?. Antibiotics. Capsule or Mucilage; Protection. Disease-causing. Decompose dead organisms; Recycle nutrients. 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).
