Heya !!!

Here's your answer !!!

Phanerogams are the flowering plants of the plant kingdom.... They are also called as Spermatophytes...

They are two groups namely Gymnosperms and Angiosperms

▶ Gymnosperms :
➡ In Gymnosperms , ovules are not enclosed by the ovary....

➡Direct pollination occurs...

➡In gymnosperms , pollination is Anemophilous..

➡Female gametophyte is Archegonium within the ovule...

➡ Triple fusion is absent...

➡ Female gametophyte directly act as endosperm....

➡In cycas , both siphonogamy and zooidogamy occur...

➡ Endosperm is Haploid....

➡Ovules in gymnosperms are integumented and naked. ...

➡No fruit formation....


▶ Angiosperms :

➡In angiosperms, ovules are enclosed by ovary...

➡ Indirect pollination occurs....

➡ Pollination in Angiosperms may be Anemophily or Hydrophily or Zoophily...

➡ Female gametophyte is embryosac within the ovule....

➡ Triple fusion is present...

➡PEN i.e primary endosperm nucleus act as Endosperm...

➡In Angiosperms , only siphonogamy occurs...

➡ Endosperm is Triploid...

➡In Angiosperms, the ovules may be ategmic , unitegmic or bitegmic and enclosed by ovary...

➡ Fruits are formed....
