An inner layer of cells, known as the tapetum, provides nutrition to the developing microspores and contributes key components to the pollen wall. Mature pollen grains contain two cells: a generative cell and a pollen tube cell. The generative cell is contained within the larger pollen tube cell. Upon germination, the tube cell forms the pollen tube through which the generative cell migrates to enter the ovary. During its transit inside the pollen tube, the generative cell divides to form two male gametes (sperm cells). Upon maturity, the microsporangia burst, releasing the pollen grains from the anther]]> 2020-12-10 01:43:25 UTC https://padlet.com/MadamNash/lsvhoxyfs8h0nqdo/wish/1004681580 ques 3 mms2023110519 https://padlet.com/MadamNash/lsvhoxyfs8h0nqdo/wish/1004684848 cells within pollen sacs are called microsporocytes. each of microsporocytes cell is diploid. they will divide by meiosis to produce 4 microspores.
4 micropores are called tetrad of tetraspores and they are haploid.

each microspore will divides by mitosis to form 2-celled microspore. and then will differentiates into pollen grain by developing heavy, thick. and sculptured wall around itself.
and at this stage the pollen grain is an immature male gametophyte.

pollen grain will mature when the generative nucleus divides by mitosis to form two sperm cells. Usually mitosis occurss after pollen grains lands on stigma of carpel.

carpel is located in the centre of flower.

sepals are leaf0like ijn shape and usually in green colour.
they cover and protect the flowers part when flower is a bud.
the collective term for all the sepals of a flower is called a calyx.

carpen has 3 parts:
petals, stamens and carpel.

the female gametophytes are egg-producing structures called embryo

for MALE reproductive organs are called stamens.
stamen has 2 parts.
