Male gametes in angiosperms are formed by
1 Mitotic division in vegetative cell
2 Mitotic division in generative cell
3 Meiotic division in generative cell

Sporopollenin is chemically
1 Fatty substance
2 Protein
3 Homopolysaccharide
4 Heteropolysaccharide
Explanation:
Sporopollenin is the main component of exine of spores and pollen. Chemical analysis has revealed that it is a biopolymer that contains majorly long chain fatty acids, phenylpropanoids, phenolics, carotenoids and xanthophyll.

The germ pores in the pollen grain are the regions:
1 That can withstand high temperature and strong acids and alkalies
2 Through which sperms are released into the female gametophyte
3 Which are made up of lignin and suberin
4 Which lack sporopollenin
Explanation:
The exine is thin at several places and consists of apertures known as germ pores. At these places, sporopollenin is absent. The function of germ pores is to allow pollen tubes to emerge during germination of pollen grain.

Male gametophyte of angiosperm is
1 Microspore
2 Microsporangium
3 Nucellus
4 Stamen
Explanation:
Microspore is haploid, uninucleate, minute spore produced in large numbers as a result of meiosis in microspore mother cells inside the microsporangia. These are the first cell of gametophytic generation in angiosperm.
