module 5- reproduction Flashcards
what is sperm?
-it is the male sex cell in animals
-it is a small cell with a tail to allow it to swim
-it is haploid
-it has a nucleus in its head
what is an ovary?
it is the site of female gamete (egg) production in plants and animals
what is a gamete?
a haploid sex cell
what is an egg?
-female sex cell in animals
-large cell
-contains food storage and haploid nucleus
what is an anther?
it is the site of male gamete (pollen) production in plants
what is fertilisation?
the fusion of male and female gamete nuclei to form a diploid zygote
what is a haploid?
it is a cell that contains 1 set of chromosomes
what is a diploid?
it is a cell that contains 2 sets of 𝗺𝗮𝘁𝗰𝗵𝗶𝗻𝗴 chromosomes
what are testes?
they are the site of male gamete (sperm) production in animals
what is a zygote?
it is a diploid fertilised egg that will develop into the embryo, it is also genetically unique and increases variation within a species
what is pollen?
it is the male sex cell in plants
what is the oviduct?
site of fertilisation in humans
is the egg haploid or diploid?
haploid, which means it has 23 chromosomes
is sperm haploid or diploid?
haploid, which means it has 23 chromosomes
is the zygote haploid or diploid?
diploid, which means it has 46 chromosomes
what is restored during fertilisation?
the full chromosome complement of a cell
how is a zygote formed?
the nucleus of the male gamete fuses with the nucleus of the female gamete to form a zygote
how is an embryo formed?
the embryo is formed after the zygote has divided
what is the female gamete in plants and where is it produced?
the female gamete cell in plants are ovules, and they are produced in the ovaries
