Autotrophic Nutrition Photosynthesis
Posted in Health and Nutrition on 05/07/2008 02:54 pm by Steven Nerenbergbiology help'm a little confused about this filling 1 in XX?
othere evidence of endosymbiosis: first protists bacteria themselves and the bacteria became XX (internal symbionts) formed mitochondria and chloroplasts! oThree major groups, depending on the mode of nutrition (ie is a bit clearer how the text groups them!) xx = Like animals protists (heterotrophic) • Grouped by how they move: ciliates, amoebas, flagellates, Sporozoa • [Know the characteristics of the types discussed in the text] xx = type plant protists (autotrophs: You can perform photosynthesis) • grouped by color (pigment type): green, red, brown • The diatoms and brown algae should be in this group because they are autotrophs! molds water and mold xx = similar to fungi protists (heterotrophic decomposers)
Dear Mother First take live questions answered you are welcome to the ongoing series on biology at 19:00 IST wiziq.com as July 13 is the session of the fungi. So get to your question: 1. Endosymbiont THEORY: Lynn Margulis, suggests that mitochondria and chloroplasts are derived from prokaryotes that were taken by a much larger cell. Perhaps mitochondria were originally aerobic heterotrophic bacteria and chloroplasts were originally cyanobacteria. The host cell that have benefited from the ability to use oxygen or synthesize organic foods, when by chance the prokaryote was not destroyed. Therefore, after these prokaryotes entered by endocytosis, a symbiotic relationship was established. Evidence endosymbiotic hypothesis of the following: 1. Mitochondria and chloroplasts are similar to bacteria in size and structure. 2. Both are bounded by a oragnelles double membrane can be derived from the outer membrane that surrounds the bladder and the interior can be derived from the plasma membrane of prokaryotes original. 3. Mitochondria and chloroplasts contain a limited amount of genetic material and are divided by division. Your DNA (deoxyribonucleic acid) is a circular, such as bacteria. 4. Although most proteins in mitochondria and chloroplasts are produced by the eukaryotic host, which have their own ribosomes and they do produce some proteins. Their ribosomes resemble those of bacteria. 5. RNA (ribonucleic acid) base sequence of the ribosome suggests a eubacterial origin of chloroplasts and mitochondria. 6. The protein synthesis in the chloroplast and mitochondria is also inhibited by antibiotics which have similar effects on the ribosomes of bacteria, but not made in nuclei. These similarities between these organelles and bacteria are evidence of the hypothesis of the origin or endosymbiotic chloroplasts and mitochondria. Similarties physiological and genetic also point to the largest group of bacteria as a source of the ancestors of these organelles. For example, one member existing in this group, Prochlorothrix contains chlorophyll, which is known only in plants and some algae. Other photosynthetic bacteria lack this pigment. However, other pigments certain bacteria similar to the chloroplasts of red algae. Your second question petaining to Protista: The most diverse group of organisms on the basis of food 1. PROTISTS PLANT … Alaga for autotrophic 2. Protista ANIMAL .. PROTOZAONS .. 3 HOLOZOIC or SAPROZOIC for heterotrophs. ADVANCED PROTISTS .. SLIME MOLDS .. Saprophytes and fungi. Enjoy http://bisbio.in
