|
|
seed cones
|
produce female gametophytes, larger than pollen cones, in gymnosperms
|
|
|
ovules
|
structure in seed cones in which female gametophytes develop, Angiosperm
|
|
|
pollen tube
|
structure grown by pollen, contains two haploid sperm nuclei, carry male gametophyte
|
|
|
petals
|
brightly-colored structure, just inside the sepals; attract animals
|
|
|
sepals
|

|
|
|
filament
|
long, think stalk, supports the anther
|
|
|
anther
|
an oval sac where meiosis takes place, produces haploid gametophytes- pollen grain. example: Lily

endosperm
|
a food rich tissue which nourishes the seedling as it grows
