Answer 2

Heya !!!



Here's your answer !!!

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

They are Classified into two groups by the basis of presence of naked seeds and seeds enclosed by fruit...


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....
