Question

Give the short note on development of embryo in angiosperms

Answer 1

Hi.



here is your answer.


Development of embryo in angiosperms :-----


********************************


● Within ovules present highly reduced female gametophyte termed as embryo sac .


● the pollen grains germinate on the stigma and the resulting Pollen tubes grow through a tissue of stigma and style and reach the oval .



●the Pollen tube enter the embryo sac where two male gametes are disturbing one of the main game excuses with the Excel to form of zygote .



●The Other male gametes fuses with the diploid secondary nucleus to produce the triploid primary endosperm nucleus . because of the environment of to fusion this event is termed as double fertilization an event unique to endosperm



● The zygote develops into an embryo with one or two cotyledons and the pea and develops into endosperm which provides nourishment to the developing embryo




● the synegrids and antipodals degenerate after fertilization during the cement store which develops into seeds and ovaries develop into fruit .



hope it helps you ☺

Answer 2

 In angiosperms, the young plant contained in the seed, begins as a developing egg-cell formed after fertilization (sometimes without fertilization in a process called apomixis) and becomes a plant embryo. This embryonic condition also occurs in the buds that form on stems.
