During asexual reproduction in a certain organism, a new organism begins to form on the adult's body. Eventually, when the new organism is large enough, it breaks off from the adult and lives separately. This type of reproduction is known as
parthenogenesis.
binary fission.
budding.
regeneration/fragmentation.
Which of the following is an example of binary fission?
An unfertilized egg develops into a worker or drone in a bee hive.
A starfish is cut into two pieces. Each piece forms into a whole starfish.
A seed from an apple germinates.
A bacterial cell undergoes mitosis.
What type of reproduction is happening in this hydra?
binary fission
parthenogenesis
fragmentation/regeneration
vegetative propagation
Which of the following is not an example of vegetative propagation?
I wrap some bean seeds in moist paper towels. After a few days, the seeds have sprouted.
I go to my pantry and find that there are several sprouts growing out of a potato.
I cut a stem from a rose bush and put it in some water. It forms roots, so I then replant it in my yard.
A strawberry plant sends out horizontal stems that take root and grow into whole new plants.
Some organisms can reproduce both sexually and asexually.
True
False
A hydra reproduces when an outgrowth, or bud, forms and continues to develop until it falls off of the parent. This is an example of:
Binary Fission
Sporulation
Budding
Vegetative Propagation
Fishermen work hard to catch and remove all the starfish that get into their favorite shell fishing beds and the “underwater farms” where they raise clams and oysters. In the past, they put the starfish into their boats, cut them up with knives, and then throw the pieces of starfish overboard. They thought this would kill the starfish. What they did not know was that each piece of starfish will grow into a whole new animal.
Which is a type of Asexual Reproduction
Sexual
Binary fission
Cells
organism
A planarian is a non-parasitic flatworm. If a planarian was injured by a predator, it could re-grow its body parts. If the body parts were not eaten by the predator, the part could re-grow into a whole new planarian as well.
