spontaneous generation : ancient belief: life can arise from nonliving matter Key scientists of spontaneous generation : Francesco Redi, John Needham, Lazzaro Spallanzani Francesco Redi : This scientist disproved spontaneous generation by showing that maggots do not spontaneously arise from decaying meat. John Needham : Believed there was a life force that caused spontaneous generation Lazzaro Spallanzani : replicated redi and needham's experiments, disproved of spontaneous generatio...

Not very many proteins in the eukaryotic cytoplasmic membrane. Where did they go? - Answer-They are still in the membrane and they are still busy, but most of the proteins went to the mitochondrial membrane in eukaryotes. Cellulose and Chitin - Answer-Use specific b-1,4-glycosidic bonds between sugars provides strength and rigidity. In algae Fungi - Cell Wall - Answer-You have a NAG in chitin for cell walls in fungi. The cell wall is all NAGs Cytoskeleton Function - Answer-Involved in intr...

IB Biology 1.5 Latest Version Already Graded A Endosymbiotic theory a theory that some eukaryotic organelles, such as mitochondria and chloroplasts, originated as free-living prokaryotes that invaded primitive eukaryotic cells. Allowed growth of smaller cells in a cytoplasm, through endocytosis, and the rapid replication they could persist indefinitely inside the large cells. It also states that mitochondria were once free living prokaryotic organisms that had developed the process ...

Biology cells Questions and Answers with Certified Solutions What is shown in the image? eukaryote The endosymbiotic theory helps to explain the origin of which structures? mitochondria Which statement is most likely to apply to a cell that has DNA within its cytoplasm? It performs all functions for the organism. Which statement is least likely to support the endosymbiotic theory? Mitochondria and chloroplasts are much larger than prokaryotic cells. A scientist is studying a cell and can cle...

pontaneous generation - Hypothesis stating that life could arise from nonliving matter. Endosymbiotic theory - theory that eukaryotic cells formed from a symbiosis among several different prokaryotic organisms Germ Theory of disease - the principle that microorganisms cause disease Ribosomes - organelles made of protein and RNA that direct protein synthesis in the cytoplasm Prokaryotic cells - cells without a nucleus or other membrane-bound organelles Eukaryotic cells - Larger, complex, wi...

The association of ribosomes with _____ invaginations would support the _____ theory. - ANSWER membrane, endomembrane After a cell is pancake shaped in a cell culture dish, the order of events that occurs as a cell walks is? - ANSWER filapodia, lamellipodia, cell muscle, retraction fiber T/F It is presumed that the peroxisomes evolved in these primitive, protoeukaryotes to remove oxygen, which was toxic to the primitive cells. - ANSWER true T/F In an extant prokaryotic cell the outer...
