As such, they have fewer nutrients to live on and many will never become established. This is fertilisation. A diploid megaspore mother cell is produced within the megasporangium, which will divide by meiosis to produce the haploid megagametophyte (see Chapter 7.3.2: Angiosperm Life Cycle for a refresher). 3. Those things we think of as strawberry seeds aren't seeds and the big, red strawberry "fruit" isn't technically a fruit. ovary. 73 ARNOLDIA A continuation of the BULLETIN OF POPULAR INFORMATION of the Arnold Arboretum, Harvard University VocuME 27 DECEMBER 8, 1967 NUMBERS 10-11 I SEED DISPERSAL BY BIRDS AND ANIMALS IN THE ARNOLD ARBORETUM I N nature's scheme of things, many remarkable methods have been evolved for dispersal of seeds.Study of these methods is fascinating indeed, and The production of fruit aids in seed dispersal. 466) rendering them buoyant: (i) Seeds of Moringa oleifera, Oroxylum indicum, Lagerstroemia speciosa, Swietenia mahogoni, Cinchona, etc., are provided with wings developed from the testa.

The size of the seed is not a factor in determining whether or not a seed can float. Seed parts ,Seed germination process ,Seed dispersal methods for Kids . And the answer surprised me.
