Concept explainers
Introduction:
According to biology, living beings like humans, animals, bacteria, plants, and
Mitochondria and plastids have their own circular DNA (Deoxyribonucleic acid); have a size that is almost equal to that of bacteria; their composition of inner cell membrane also matches with bacterial plasma membrane and possess similar ribosomes to that of bacterial cells. They are known to have established a symbiotic relationship with eukaryotic cells after being engulfed by eukaryotic cells.

- The concept of endosymbiosis as applied to chloroplast and mitochondria found in eukaryotes: a) is based on evidence that Chloroplasts and Mitochondria were originally prokaryotes, b) changes present day animals into plants, c) explains how chemical evolution caused the appearance of life, d) allowed chloroplasts to carry out aerobic metabolism, e) all are true.arrow_forwardYou discover a new multicellular, heterotrophic, eukaryotic organism. What is one characteristic that will allow you to classify this new organism as an animal? Group of answer choices a. cell walls made of chitin b. structural proteins c. multicellular haploid stage in its life cycle d. cell walls made of cellulose e. external digestionarrow_forwardWhich one of the following is not a characteristic of all prokaryotes (Archea and Bacteria)? A. no nucleus B. smaller ribosomes than (most) of eukaryotes ribosomes C. existed before eukaryotic cells D. Contain some organelles like mitochondriaarrow_forward
- For each of the following indicate if they evolved once, twice, or perhaps several times. a) acquisition of mitochondria b) acquisition of chloroplast c) multicellularity d) origin of ribosomesarrow_forwardThe endosymbiotic theory argues that prokaryotes become some of the organelles of early eukaryotic cells. All of the following support this hypothesis Except: A. The mitochondria and chloroplasts have their own DNA and are nearly idential to some free-living prokaryotes b. Mitochondria and chloroplasts are nearly idential to some free-living prokaryotes. c. Mitochondria and chloroplasts have their own DNA d. The vacuoles can come and go across the plasma membranearrow_forwardThe extra energy required for the evolution of the highly complex eukaryotic cell was possible because: a) mesosomes released enzymes into the nucleus b) two types of prokaryotic bacteria became endo symbiotic invaders of the complex cells c) the DNA of the eukaryote cell functions within the nucleoid area d) chloroplasts were able to use O2 to conduct photosynthesis e) the space between the two layers of the nuclear membrane contained mitochondriaarrow_forward
- What features of mitochondria are similar to bacteria? Select all that apply. A. Membrane-bound ribosomes B. Cellular machinery for photosynthesis C. Independent movement D. Circular DNA similar to plasmidsarrow_forwardThe membrane structure that eventually evolved into the double nuclear membrane of the eukaryotes first appears in the: A) Chemical evolution, B) Prokaryotes, C) Eukaryotes, D) the protocell, E) Plants.arrow_forwardWhich of the following is thought to be the most closely related to the common animal ancestor? a. fungal cells b. protist cells c. plant cells d. bacterial cellsarrow_forward
- Which of the following statements is false? a. All multicelled organisms have cell walls. b. All multicelled organisms are eukaryotic c. All multicelled organisms have cell membranes. d. The nuclei of multicelled organisms are membrane-bound.arrow_forwardAccording to the theory of endosymbiosis, organelles, like mitochondria and chloroplasts, were once free-living cells that were absorbed into another cell. The relationship benefited both cells to stay together. What evidence do scientists observe today that supports the theory of endosymbiosis? Select all that apply. a There are ribosomes found inside mitochondria and chloroplasts just like there are inside cells. b Looking inside mitochondria and chloroplasts, one will find that they each contain their own DNA. c Mitochondria and chloroplasts are found inside all cell types. d Mitochondria and chloroplasts each have a membrane around them just like a cell would.arrow_forwardWhich is a piece of evidence that supports the endosymbiotic theory? Select all that apply. (Group of answer choices) A. many bacteria are resistant to antibiotics B. eukaryotic cells have cell membranes C. mitochondria have their own DNA D. chloroplast DNA is more similar to cyanobacteria DNA than eukaryotic DNA E. ribosomes are present in eukaryotic cells F. mitochondria must divide to multiply, cells can't build themarrow_forward
