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.
Answer:
Mark thinks Karen is trying to represent the democratic type of parent.
Explanation:
Karen did not impose that Daniel keep playing tennis, which indicates that she is not trying the authoritarian style of parenting. Furthermore, she is not failing to care whether or not Daniel will stop playing tennis, which indicates that she is not trying the negligent parenting style.
However, Karen preferred to explain to Daniel that playing tennis is a beneficial activity and that she is helping him to stay on the team, which made Daniel reason and realize that she was right. This is an example of the democratic type of parentability, where countries explain their opinions on a particular topic, but allow their children to make their own decisions, without imposing reprisals, and without acting as if they don't care.
