Alternation of Generations
Cards in this deck (9)
- 1Alternation of Generations
- 2Alternation of Generations (in words)The phases a plant goes through during reproduction. Plants alternate between a haploid phase (spores to gametophyte to gamete) and a diploid phase (zygote to sporophyte).
- 3gametea type of cell organisms make to reproduce sexually (in humans it's the sperm or ovum/egg)
this cell is haploid, then joins with another gamete to make the zygote (diploid) - 4zygotethe cell created when two gametes join
it is diploid - 5haploidthis describes a cell with only half the normal number of chromosomes
when organisms reproduce sexually, they create haploid cells (in humans, sperm cells or ovum/egg cells) - 6diploidThis describes a cell that has a full set of chromosomes. Most cells in an organism are diploid.
The zygote is the first diploid cell of a new organism (a baby starts as a zygote). - 7gametophyteThe haploid multicellular stage during the alternation of generations in plants.
This is the plant that produces the gamete. - 8sporophyteThe diploid multicellular stage during the alternation of generations.
In most plants, when you think of the plant, you are thinking of the sporophyte. (In flowering plants, the sporophyte is everything except the pollen and embryo sac - like whole trees). - 9sporebasically seeds
haploid and unicellular
