Bryophyta
Mosses, non-vascular
Gametophytes
Haploid generation
Gametes production
Sporophyte
Diploid generation
Spore production
Club mosses or Ground pines
top of the sporophyte life cycle of club mosses
Contain large number of Sporangia
Sporangia
Located in the strobilus of club mosses.
Where spores are produced
Whisk fern
Have dominant sporophyte generation with dichotomous branching
Sporangia form on scale leaf-like structures
True Ferns
Seedless Vascular plant
Sporangia are found on Sori
Location on True ferns where sporangia are located and produce spores
Alternation of Generations
Plant life cycle which alternates between a sporophyte dominate lifestyle and a gametophyte dominant lifestyle
Heterospory
production of two distinct types of spores in two distinct types of sporangia
Microsporangia
produce microspores
Microspores
precursor to male gametophytes (pollen grains) which produce sperm in heterosporous organisms
Macrosporangia
produce macrospores
Macrospores
percursor to female gametophytes (egg sacs) which produce eggs in heterosporous organisms

Male reproductive parts in an angiosperm
includes anther and filament
Carpels
Female reproductive parts of an angiosperm
includes Style, Stigma, and Ovary
Anther
male reproductive organ in a flower where meiosis takes place and microsporangia create male gametes (pollen grain)
Ovary
Female reproductive parts in an angiosperm with contains one or more ovules
Where meiosis takes place to create female gametophytes (egg sac)
Female reproductive parts of an angiosperm
includes a stigma, style and ovary
Male Gametophyte (consists of what?)
One Generative cell
One Tube cell
Generative cell
part of a pollen grain which eventually divides to form two sperm cells
Tube Cell
Part of pollen grain which forms a tube to the ovule where generative cell can begin fertilization
Megasporocyte
large diploid cell within ovule which undergoes meiosis to form four megaspores
Megaspore
divded via mitosis to form eight nuclei including the egg and two polar nuclei
Polar Nuclei
Part of the embryo in an angiosperm which develops into endosperm
Female parts of a flower which lead to and protect the ovary
zygote
diploid formed when egg and sperm combine
double fertilization
Union of two sperm cells with two cells in the embryo
endosperm
nourishes the embryo during development
