Module 9 Flashcards
cells from only one individual produce the offspring
Asexual Reproduction
asexual reproduction in which a female can produce an embryo without fertilizing an egg with sperm
Parthenogenesis
when animals can break body parts off or be cut in half, then regenerate the missing
portion of the body
Fragmentation
is done via the fusing of two complementary haploid cells, to produce a diploid zygote.
Sexual Reproduction
is what humans do and is when the fusion of gametes occur within the body
internal Fertiliation
the sperm
and egg fuse outside of the
organisms.
External Fertilization
is an organism that has both male and female sex organs fully developed.
Hermaphrodite
is when your genetics determine which gametes are produced (like humans).
- Genotypic sex determination
Some plants, insects, and fungi can have sex with themselves. This is called
selfing
- Produces and stores fluid, that mixes
with sperm
Seminal-Vesicle
adds more fluid and contracts
during ejaculation.
Prostate Gland
refers to the distal end of the penis and is
extremely sensitive.
Glans Penis
the production of mature sperm capable of fertilizing an egg
Spermatogenesis
is where developing embryos mature.
Uterus
is a separate opening for urination.
Urethra
the production of mature eggs capable of being fertilized
Oogenesis
Germ line cells develop via meiosis into
immature diploid egg cells called
Primary Oocytes
organisms that can change their sex from their inborn sex to the opposite sex at some point in their lives
Sequential Hermaphrodites
happens when climactic (temp.) or social factors (no females) determine which gametes are produced.
Environmental sex determination
A type of hormone made by the body that helps develop and maintain female sex characteristics and the growth of long bones.
Estrogen
a steroid hormone that plays a vital role in the reproductive system and is involved in many other bodily functions
Progestogens
is a sex hormone that helps develop and maintain male characteristics, such as the genital tract, secondary sexual characteristics, and fertility. Androgens also contribute to the anabolic status of somatic tissues
Androgen
paired embryonic structures that serve as progenitors of the male internal genitalia and are involved in the incipient development of the renal system in both sexes.
Mesonephric duct
A coiled tube that carries the sperm out of the testes
