1
New cards

microsporangia (2n)

produce microspores (1n) thru meiosis

2
New cards

microspores

develops into pollen grains (male gametophytes 1n) thru mitosis

3
New cards

Pollen grains

divide by mitosis to form 2 sperm cells

4
New cards

embryo

2n, the young shoot that will develop into the adult plant

5
New cards

embryo sac

female gametophyte within ovule of angiosperms

6
New cards

embryo sac formation

- Within each ovule, a diploid microspore mother cell undergoes meiosis to produce 4 haploid megaspores

- Usually only 1 megaspore survives, enlarges and undergoes repeated mitotic divisions to produce 8 haploid nuclei

- Enclosed within embryo sac

7
New cards

double fertilization

One sperm fertilizes egg, another forms endosperm.

8
New cards

endosperm (3n)

nutrient-rich tissue formed by union of a sperm with two polar nuclei during double fertilization.

provides food to developing embryo in seeds.
