Gametogenesis
- What are gametes?
Gametes are cells specialized in sexual
reproduction.maximum number of chromosom They contain half of thees of (^)
the species and unite with another
gamete double of the number of chromosomgiving birth to a zygote with (^) es
of the gametic cells.
In humans gametes are formed by
meiosis; the male gametes are sperm cells and the female gametes arethe (^)
the egg cells.
- What is the type of cell
division that allows sexual
reproduction? What is
gametogenesis?
Meiosis is the type of cell dallows sexual reproduction since ivision thatit
reduces to a hchromosomes oalf the number off the species making (^)
possible the combination of two
gametes to some beings meiosisform a new individual. ( creates haploidIn
gametophytes that by means of mitosis
generate gametes. Even in this case thefunction of meiosis is the same: to
provide cells with half of the number of
chromosomes oseparation of the homologous.)f the species with
Gametoprocess of genesis is the name given to thgamete production. e
- What is the name of the
cells capable of making
gametes? What is the ploidy
of these gamete-forming
cells?
The cells that form gametes are thegerm cells as opposed to the somatic (^)
cells. The ploidy (number of
chromosomes) osame as the somaticf the germ cells is the cells (only during (^)
the formation of gametes meiosis occurs
and the number of chromosomreduced to half). es is
- What are gonads? What are
the male and the female
gonads in humans?
Gonads are gametes. They contain ththe organs that pre germ cellsoduce (^)
that undergo division and generategametes. In males the gonads are the (^)
testicles. In females the gonads are the
ovaries.
- Indicating the name and
respective ploidy of each
involved cell how can the
formation of sperm cells from
germ cells be described?
The formation spermatogenesis, begins with a gof sperm cells, or (^) erm
