5.4 Asexual Reproduction KEY CONCEPT Many organisms reproduce by cell division. 5.4 Asexual Reproduction • I can compare and contrast binary fission and mitosis. • I can describe how some eukaryotes reproduce through mitosis. 5.4 Asexual Reproduction Binary fission is similar in function to mitosis. • Asexual reproduction is the creation of offspring from a single parent. – Binary fission produces two daughter cells genetically identical to the parent cell. parent cell – Binary fission occurs in prokaryotes. DNA duplicates cell begins to divide daughter cells 5.4 Asexual Reproduction • Environment determines what form of reproduction is most advantageous. – Asexual reproduction is an advantage in consistently favorable conditions. – Sexual reproduction is an advantage in changing conditions. 5.4 Asexual Reproduction Some eukaryotes reproduce through mitosis. • Budding forms a new organism from a small projection growing on the surface of the parent. Hydra bud Yeast 5.4 Asexual Reproduction • Fragmentation is the splitting of the parent into pieces that each grow into a new organism. • Vegetative reproduction forms a new plant from the modification of a stem or underground structure on the parent plant. 5.4 Asexual Reproduction The most common form of reproduction among prokaryotes is • a. sexual reproduction. • b. binary fission. • c. budding. • d. fragmentation. 5.4 Asexual Reproduction What is the main difference between binary fission and mitosis? • a. There is no DNA replication in binary fission. • b. Two parents are required for mitotic reproduction. • c. Binary fission occurs in single-celled organisms only. • d. Mitosis takes place only in sexual reproduction. 5.4 Asexual Reproduction Which of the following statements is true of asexual reproduction? • a. It produces few offspring. • b. It produces genetically identical offspring. • c. It produces genetic diversity. • d. It produces offspring that are resistant to antibiotics. • 5.4 Asexual Reproduction Starfish that reproduce by splitting into pieces are reproducing by • a. binary fission. • b. vegetative reproduction. • c. budding. • d. fragmentation. 5.4 Asexual Reproduction Vegetative reproduction, budding, and fragmentation are examples of • a. asexual mitotic reproduction. • b. reproduction through binary fission. • c. prokaryotic colony formation. • d. increased genetic variation.
