Asexual vs Sexual Flashcards
what is asexual reproduction?
a single parent organism producing offspring that are genetically identical to itself.
true or false: sexual reproduction involves two parents.
true
fill in the blank: In asexual reproduction, the offspring are _____ to the parent organism.
identical
name a advantage of asexual reproduction.
only one parent needed, produces a lot of offspring
which of the following is NOT a method of asexual reproduction? a) budding b) fragmentation c) fertilization
c) fertilization
what is a disadvantage of sexual reproduction?
takes a long time, produces 1-2 babies at a time
true or false: in sexual reproduction, offspring inherit traits from both parents.
true
what is fertilization?
fertilization is the process where male and female gametes combine to form a zygote.
list 3 examples of asexual reproduction
regeneration, budding, binary fission, parthenogenesis, sporulation, vegetative propagation
multiple choice: which process involves the exchange of genetic material? a) asexual reproduction b) sexual reproduction
b) sexual reproduction
what is sexual reproduction?
involves the fusion of gametes (sperm and egg cells) to produce genetically unique organisms
true or false: asexual reproduction requires two parents.
false
what is binary fission?
an organism duplicates its genetic material (DNA) and then divides into two parts with each new organism receiving an exact copy of the DNA. (ex. bacteria)
fill in the blank: __________ is a form of asexual reproduction where the organism is capable of regrowing certain body parts
regeneration (ex. starfish)
which type of asexual reproduction develops from some generative anatomical point of the parent organism?
Budding (ex. yeast)
what type of asexual reproduction does adult organisms produce single-celled diploid spores that grow into adults themselves?
sporulation (ex. fungi)
what is vegetative propagation?
a new plant grows from a fragment or cutting of the parent plant (ex. stems)
what is parthenogenesis?
spontaneous (random) development of an embryo from an unfertilized egg cell. (ex. reptiles)
what is a advantage of sexual reproduction?
a lot of genetic variation, better parental care- more likely to survive
name a disadvantage of asexual reproduction
little parental care, no genetic variation (vulnerable to diseases)
