question 84

Short Answer

The following diagram depicts the life cycle of a cherry, a eudicot. Match the specified labels in the diagram with the corresponding life cycle stage. a.The pollen tube reaches the ovule, penetrates it, releases two sperm cells, and double fertilization occurs.
b.Mitosis of a microspore followed by differentiation results in a two-celled pollen grain.
c.Three megaspores disintegrate; in the remaining megaspore, three rounds of mitosis without cytoplasmic divisions produce a single cell with eight haploid nuclei.
d.Pollen grain lands on a receptive stigma and germinates.
e.An ovule forms in the ovary and a cell in the ovule enlarges.
f.Pollen sacs form in an anther.
g.Four haploid (n ) megaspores form by meiosis of the enlarged cell in the ovule.
h.Four haploid (n ) microspores form by meiosis of a cell in the pollen sac.
i.Uneven cytoplasmic divisions produce a seven-celled female gametophyte.
j.When the pollen sacs split open, the anther releases pollen grains.
