Botany : Alterations Of Generations Flashcards
Gametophyte
Sexual and produces gametes
Sporophyte generation
Asexual and produces spores
Diploid
Total number of chromosomes in body cells 46 chromosomes (2n)
Haploid
Total number of chromosomes in gametes (sperm and eggs) 23 chromosomes (n)
Mitosis
Nuclear division in which daughter cells are produced from single parent cell with no change in chromosome number
Meiosis
Nuclear division producing haploid cells from a single diploid cell (involves 2 cycles of division)
Fertilisation
the action or process of fertilizing a plant, involving the fusion of male and female gametes to form a zygote.
Germination
Germination is usually the growth of a plant contained within a seed
Sexual reproduction
2 parents are involved and their genetic material combines
Asexual reproduction
Only one parent is involved and all offspring have the same genetic composition as the parent
