Fill in the blank. After fertilization, the zygote
will undergo multiple divisions to form the blank. (A) Fruit, (B) embryo, (C) pollen
tube, or (D) cell membrane.
You may remember that fertilization
is the process where male and female gametes, that is, egg and sperm, fuse during
the process of sexual reproduction. The cell that results from
fertilization is called the zygote. This is the first cell of the
offspring. This cell will then divide, and
each of those cells will then divide, and so on, during the process of the
development of that offspring.
Once the zygote cell has divided
into multiple cells, it is referred to as an embryo. The fruit that develops will often
carry the seed that contains the embryo. However, the cell divisions of the
zygote itself do not form the fruit. The pollen tube is what carries the
pollen to the ovary after pollination and before fertilization. And the cell membrane is part of a
cell, not something produced by multiple divisions of a cell.
Therefore, the correct answer to
this question is (B), embryo. After fertilization, the zygote
will undergo multiple divisions to form the embryo.
