What is the floral part?
Sepals = Calyx
Receptacle
Pistils = Carples
In Magnolia, we see muliple, unfused
carpels. Each is considered a pistil.

What floral parts are fused?
The sepals are fused together. The petals (corolla) are
fused together, and the stamens are fused to the corolla.
Two carpels are fused to form a compound pistil.

and nucellus
What is the structure of lily?
8-nucleted, 7-celled megagametophyte
This is the mature megagametophyte.
What is the structure of lily?
The central cell of the mature megagametophyte
with two nuclei.
What are these cells of lily?
The center cell is the egg. The other two are synergids.
Together, these three cells are the egg apparatus
What are these cells of lily?
These three cells are the antipodals.
What is this cell of lily?
This is one sperm nucleus undergoing karyogamy with the
egg nucleus to generate the zygote.
