Asexual reproduction
Asexual reproduction Cuttings
Asexual reproduction: Grafting
stock = main body (usually roots & some stem)
scion = new plant part
Asexual reproduction:Tissue culture
artificial seeds
(usually use alginate to encapsulate)
Asexual reproduction
seeds without sex
Eudicot flower
= microspore mother cell
(tetrad arrangement)
Making a male gametophyte
2-3 cells
Eudicot flower
= megaspore mother cell
Making a female gametophyte
micropyle
7 cells
