Animal Reproduction Flashcards
these are known as sex cells
gametes
individuals arise from outgrows
budding
union of egg and sperm
fertilization
reproduction which involves the union of gametes
sexual reproduction
separation of 1 parent into 2 or more individuals
fission `
2 classifications of reproduction
sexual and asexual
this accompanies fragmentation; is the regrowth of lost body parts
regeneration
known as “virgin birth”
parthenogenesis
the release of mature egg cells
ovulation
creation of offspring without union of sperm and egg
asexual reproduction
breaking of body parts that develop into adults
fragmentation
one organism with both male and female reproductive organs
hermaphrodite
common opening in nonmammalian vertebrates of the digestive, excretory, and reproductive system
cloaca
sex organs that produce gametes
gonads
male gonads
testes
female gonads
ovaries
male gametes
sperm
female gametes
egg
what forms when a sperm and egg fuse?
zygote
reproduction seen in sea stars
fragmentation
reproduction seen in earthworms
hermaphroditism
reproduction seen in hydra
budding
reproduction seen in sea anemone
fission
give 3 benefits of sexual reproduction
- more variation in species
- increases rate of adaptation
- gene shuffling or recombination eliminates bad genes
which type of reproduction produces more gametes?
asexual reproduction
which type of reproduction provides more protection and parental care?
sexual reproduction
