Answer:
Cell of and integument
Explanation:
When flowering plants reproduce by sexual reproduction, they form seeds contained into fruits. The fruit is derived from the maturation of the flower's ovary (female part) after fertilization.
A mature seed contains three generations:
- a diploid embryo (the new sporophyte),
- The embryo is surrounded by haploid female gametophyte tissue that supplies nutrition
- All the above structure is in turn surrounded by the seed coat (diploid parental sporophyte tissue). The seed coat is produced by integument cells to protect the embryo during its development and before its can germinate. As it is produce by it parental plant, its ploidy level diploid.
In contrast, the generative nucleus and sperm cell are part of male gametophyte (pollen grain) and therefore haploids. Synergid cell is part of embryo sac, therefore belongs to female gametophyte and thus being haploid. Finally, cell of endosperm is usually derived from the fusion between a sperm cell and one of the two female gametes present within the embryo sac, thus being triploid.
The answer is thinner. the air gets thinner :)
I might go in there on mondays and fridays
because the flowering plant is very important
if you don't make it
you may damage them
good lucks :)
Answer:
This could mean that the pink ball had a little bit more air in it than the blue ball. They could also have been dropped at the same time, but they were dropped on a hill, and the pink one landed first at the top of the hill, and the blue one landed second at the bottom of the hill.

Have a nice day! :)
Hello there!
For a cell to be responsive to a lipid-soluble hormone, it must have <span>a specific receptor in the cytoplasm or nucleus. I hope I was able to help you, and you're welcome :)
