Concept #1: Endosymbiotic Theory and Mitochondria

Concept #2: Chloroplasts and Peroxisomes

Practice: Endosymbiotic theory is supported by the discovery of non-nuclear DNA in the _________ and __________ organelles.

Practice: Mitochondria have a single membrane.

Practice: Chloroplasts carry out what process?

Additional Problems
Chloroplasts contain their own DNA, but the genes on these chromosomes only encode about 10% of the proteins required for photosynthesis. This is evidence for:  a. competition. b. photosynthesis. c. predation. d. parasitism. e. endosymbiosis.
Multicellularity and endosymbiotic relationship is not observed in a. animalia b. planta c. bacteria d. fungi e. protista
In eukaryotic cells DNA is found in the:  a. Nucleus b. Chloroplasts c. Mitochondria d. All are correct
The theory of endosymbiosis is based on:  a. The knowledge that ribosomes are structures found in bacteria, plants, and animals b. The experiments in which bacteria were made to grow in plant cells forming chloroplasts c. The knowledge that chloroplasts and mitochondria resemble bacteria d. Similarities between chloroplasts and other organelles in animals
An organelle found in plant cells and some members of the kingdom Protista but not in animal cells is:  a. A centriole b. A ribosome c. A cell membrane d. A lysosome e. A chloroplast
Chloroplasts are not:  a. Glucose factories b. Responsible for respiration c. Found in plants d. Organelles that carry out photosynthesis e. Found in members of the kingdom protista
Mitochondria do not:  a. Have their own DNA b. Extract energy from nutrients c. Have two membrane layers d. Have cristae e. Carry out photosynthesis
Unlike most organelles, chloroplasts and mitochondria contain:  a. Membranes b. Ribosomes and DNA c. Ribosomes d. DNA e. Membranes and ribosomes
A wild duck needs a steady supply of energy to be able to fly for hours and has dark breast meat. Domesticated chickens rarely fly and have white breast meat. As a result you would expect to find _____ in the breast muscles of wild ducks than domesticated chickens. a. Fewer mitochondriab. More cytoplasmc. Less cytoplasmd. More Golgie. More mitochondria
In eukaryotes, mitochondria are the organelles primarily involved ina.  energy release/captureb.  phospholipid assemblyc.  export of enzymesd.  lipid synthesise.   protein synthesis
Endosymbiosis is a theory based on the resemblance of chloroplasts and ribosomes to bacteria.  a. True b. False
Endosymbiosis is a theory based on the resemblance of chloroplasts and mitochondria to bacteria.  a. True b. False
Describe the different functions for a mitochondria and a chloroplast.
Describe three symbioses that include protists.
Some of the strongest evidence for the Endosymbiotic Theory comes from specific features of the mitochondria and chloroplasts in eukaryotic cells. Describe at least three features of these organelles that suggest that they had a prokaryotic origin.
