Which of the following is an advantage of asexual reproduction?
a) It is a slow process.
b) Two parents are needed.
c) The organism can increase in number quickly.
d) It introduces genetic diversity in the offspring.
Which of these choices describes a zygote?
a) a structure or organ within an organism that produces gametes
b) a cell that forms as the result of fertilization and has a full set of chromosomes
c) a spore-like cell that is produced during asexual reproduction and can grow into a new organism
d) a specialized cell that contains half the number of chromosomes found in other cells of an organism
Which of these statements correctly describes a difference between asexual and sexual reproduction?
a) Asexual reproduction increases genetic diversity, but sexual reproduction does not.
b) Asexual reproduction involves one parent, and sexual reproduction involves two parents.
c) Asexual reproduction increases a species' chances of surviving unfavorable conditions, but sexual reproduction does not.
d) The offspring produced by asexual reproduction are not identical to each other but those of sexual reproduction are identical
Which reason best explains why reproduction is necessary?
a) Environmental conditions might change.
b) Reproduction requires complex body structures.
c) Reproduction increases the genetic variability of the species.
d) The survival of every species depends on the ability of organisms to reproduce.
Which of these statements is true of sexual and asexual reproduction?
a) Both types of reproduction requires two parents.
b) Both types of reproduction result in offspring that are identical to parent to offspring.
c) Both types of reproduction enable genetic information to be passed from parent to offspring
d) All organisms can reproduce sexually and asexually, depending on environmental conditions.
Which statement about a zygote that forms by fertilization is correct?
a) A zygote has a full set of chromosomes, half from each parent
b) A zygote has half the full set of chromosomes from one parent.
c) A zygote has two full sets of chromosomes, one set from each parent.
d) A zygote has half the full set of chromosomes, one-fourth from each parent.
Which of these statements is true of asexual reproduction?
a) It produces offsprings genetically identical to each other and requires one parent.
b) It produces offspring genetically identical to each other and requires two parents.
c) It produces offspring genetically different from each other and requires one parent.
d) It produces offspring genetically different from each other and requires two parents.

b) binary fission, budding, spore formation
c) fertilization,vegetative reproduction, binary fission
d) spore formation, fertilization, vegetative reproduction
When an organism reproduces by budding, how does the new organism start growing?
a) from within the parent organism
b) from the merging of two parent organism
c) from a spore produced by a parent organism
d) from the outer surface of the parent organism
Which of these statements best describes what happens during vegetative reproduction?
a) A single-celled organism divides into two new organism.
b) A parent plant produces spores, which grow into new plants.
c) A new plant develops from a stem or root of its parent plant.
