Answer:
Step 1: Pollination
In general, male gametes are contained in pollen, which is carried by wind, water, or wildlife (both insects and animals) to reach female gametes. The pollen is deposited on a plant's stigma, which is part of the pistil (the elongated part of a flower extending from the ovary). This process is called pollination.
Step 2: Germination
Within a few minutes, pollen tubes begin growing, or germinating, toward the egg cell. These tubes will provide a path for the sperm carried in the pollen to reach the egg.
Step 3: Penetration of the Ovule
The pollen tubes penetrate the ovule, which contains the female gametes.
Step 4: Fertilization
Sperm travel down the pollen tubes and fertilize an egg. Most angiosperms undergo double fertilization, where both an egg and the polar nuclei in the embryonic sac are fertilized.

Explanation:
Each chromosome represents a twin.like pairs of socks.
This is an analogous problem: you have 2 pairs of socks, one white, one black. Each of the sock is tailored to a specic foot, right or left. How many different ways can the socks be mixed and matched , one for each foot?
Here are the possibilities : left = black, right = black is one such match. Left = white, right = black is another.
so also we will have 23 chromosome pairs
