What do budding, binary fission and spore formation have in common ?
They require two parents
They require only one parent cell
They produce only one daughter cell
They are all forms of sexual reproduction
Which of the following methods do bacteria that cause tooth decay and cavities reproduce?
Budding
Binary fission
Spore formation
Vegetative reproduction
What are the end products of binary fission?
Two independent daughter cells that are identical to each other
One daughter cell that is genetically different from the parent
Two independent daughter cells that are different from each other
Two daughter cells that are genetically different from the parent cell
Yeast reproduce by
Budding
Binary fission
Spore formation
Vegetative reproduction
During budding, what is usually formed?
A bud from the daughter cell
New DNA from the parent cell
An outgrowth from the parent organism
New stems and roots
Which method does mould use to produce more mould on a piece of cheese or bread?
Budding
Binary fission
Spore formation
Vegetative reproduction
Which of the following best describes when spores or bacteria will grow and divide?
When they are inside a dying host organism
When they are in an environment with harsh conditions
When they are in an environment with favorable conditions
When the existing organism is dying
Asexual reproduction requires
Only one parent to produce offspring
Two parents to produce offspring
A combination of parents to produce offspring
Two clones to produce offspring
Bacteria reproduce by
Budding
Binary fission
Spore formation
Vegetative reproduction
One disadvantage of asexual reproduction is
A species cannot survive when predators increase
Large colonies can out compete other organisms for nutrients and water
Large numbers of offspring reproduce slowly
Extreme temperatures can wipe out entire colonies
One key advantage of asexual reproduction is
Offspring complete for food and space
It allows organisms to reproduce quickly
Extreme temperatures can wipe out entire populations
Offspring are different than parent organism
The stage of bacterial growth where a population of bacteria undergo a period of rapid growth is
The lag phase
The exponential or log phase
The stationary phase
The death phase
The stage on the bacterial growth curve where a population of bacteria is stable is
The lag phase
The exponential or log phase
The stationary phase
The death phase
The stage on the bacterial growth curve where a population of bacteria begins to rapidly decline is
The lag phase
The exponential or log phase
The stationary phase
The death phase
