Ans:

Pine Pine Embryo Diploid Sporophyte Staminate cones Diploid Sporophyte Sporophyte Diploid Ovulate cones Diploid Sporophyte Microspores Pine pollens Haploid Gametophyte Megaspores Haploid + Gametophyte

Explanation: Pine is a tall, evergreen treen and the main plant body is sporophyte and diploid in nature. Fertilization between male nuclei and egg cell gives rise to diploid zygote, This zygote undergoes several division and produces diploid embryo which is also sporophyte and this embryo cotains suspensors, cotyledons, radicle, hypocotyl, endosperms. Both the staminate and ovulate cones are diploid and sporophytic nature. The staminate cone is small and oval in shape and consists of microsporophylls while the ovulate cone is large and consists of megasporophylls with ovuliferous scale. Both microspore and megaspore are haploid and gametophytic in nature. The microspre is also called pollen contains two wings.
