Sexual and Asexual Reproduction Quiz Review
1. List and describe the 5 types of asexual reproduction.
Binary Fission – one cell breaks into two cells with the same DNA. Example – bacteria.
Budding – Offspring begins to form on parent organism and breaks off when it is mature enough to survive on its own.
Example – Hydra
Fragmentation – Parent organism breaks and each piece forms a new organism. Example – star fish
Spore Formation – Parent organism undergoes frequent cell division to produce many identical cells. Example –
Mushrooms or mold
Vegetative Reproduction – Offspring are formed from runners that the parent organism sends out. Example –
strawberry, spider plant, mint
2. List and describe the 3 types of sexual reproduction.
Separate Sexes – Male and female organisms are separate and are required to reproduce. Males are XY and Females are
XX. Example – most mammals
Conjugation – two cells come into contact and exchange small pieces of DNA. Example – Bacteria
Hermaphrodites – The organism is able to produce both male and female sex cells. Example – earth worms, tomatoes
