Select all of the true statements concerning the prokaryotic ancestors of mitochondria and chloroplasts: Chloroplasts arose from prokaryotes with circular DNA. Mitochondria arose from ancestors that contained numerous linear chromosomes. Mitochondria arose from aerobic heterotrophic bacteria. Mitochondria arose from cyanobacteria. Chloroplasts arose from photosynthetic prokaryotes. Which of the following statements support the endosymbiotic theory of eukaryotic origin? Mitochondria and plastids reproduce by splitting. all of these. Mitochondria and plastids contain DNA in the form of circular molecules. Mitochondria and plastids contain special ribosomes and transfer RNAs.

Which of the following statements regarding the endosymbiosis theory is TRUE? A) Chloroplasts and mitochondria used to have smaller genomes when they were free-living organisms, but now need more genes in order to carry out tasks for their eukaryotic hosts. B) There can sometimes be transfer of genes between closely related species. C) The endosymbiosis theory tells us how the eukaryotic cell first arose. D) Cyanobacteria arose when a chloroplast was lost from a primitive eukaryote due to a mistake in cell division. E) Strong evidence in support of the theory is that the DNA of chloroplasts and mitochondria is very closely related to DNA sequences from 2 different groups of bacteria.

Which of the statements are true of endosymbiotic theory? - explains the origin of all organelles found within a eukaryotic cell - explains the origin of some eukaryotic organelles, such as chloroplasts - provides insight about why mitochondria can survive outside of a eukaryotic cell - states that an ancestral eukaryotic cell engulfed an aerobic protobacteria - explains why mitochondria contain a double membrane

Which of the following statements are correct? Explain your answers. A. The hereditary information of a cell is passed on by its proteins. B. Bacterial DNA is found in the cytosol. C. Plants are composed of prokaryotic cells. D. All cells of the same organism have the same number of chromosomes (with the exception of egg and sperm cells). E. The cytosol contains membrane-enclosed organelles, such as lysosomes. F. The nucleus and mitochondria are surrounded by a double membrane. G. Protozoans are complex organisms with a set of specialized cells that form tissues, such as flagella, mouthparts, stinging darts, and leglike appendages. H. Lysosomes and peroxisomes are the sites of degradation of unwanted materials.
