sexual reporduction Flashcards
what is a diploid cell?
the bodies of most animals and plants ontain diploid(somatic cells and gametes )he bodies of most animals and plants ontain 2 sets of chromosomes each in geir nucleas that contain two sets of chromosomes
what is a haploid cell?
cells that contain a single set of chromosomes in its nucleas are called haploid.gametes are haploid
what is fertilisation?
fertilasation is the fusing at the nucleas of a male gamete with the nucleas of a female gamete is called fertilisation.sexual reproduction produces genetically new organisms
what is the function of the bladder?
where urine is stored
what is the function of the sperm duct?
a vessel for mature sprem to trsvel from the testes to the urerthra

what are semeforuous tubules lined with?
prematuee cells that divide to produce sperms

supports the anther
what is the function of the petal ?

what is the fumction of the stem?
holds the plant upright
what is the function of the ovary? plant
contains the ovules (female gamete)
what is the fumction of the anther?
contains the polle(male gamete)
what is the function of the style?
tube like sructurethat connects the stigma and the ovary
what is the male gamete(plant)?
pollen
where is pollen produced?
in the anthers
how can pollen be ditrubuted to other plant?
by wind or pollinators(bees and wasps)
what is the female gamete in plants?
