Fertilization in a any type of flower. It happens when 2 flowers ( one male and one Female) take their 2 haploid cells and come together to create a diploid zygote. The gamete cells each has one pair of their parents chromosomes. The only way to grow an embryo is that the 2 haploid cells have to come together as one. Each different flowers as it own pistil (female part) and a stamen (male part). Even though every flower has these 2 parts they still need a pollinator (bee or the wind for example) to carry the pollen grain (sperm) to another flowers pistil. the pollen grain starts its journey on the anther (the top of the stamen) and is full of the flowers sperm. Then it waits for a pollinator to come down ,and when it starts to rub up against the anther it's letting the pollen grain stick to them. Then it stays on their until the pollinator travels to another plant. Here the grain sticks to the stigma of that plant and stretches or shrinks the pollen tube depending on the gain size. Then the gamete sperm cells travels down the pollen tube were it eventually lands in the flowers ovary(the eggs) inside the ovule, which then fertilizes the eggs to create a gamete cell (embryo). The gamete cell is created by taking the 2 parents different traits (chromosomes) and combining those 2 as one.
In order to create a gamete cell you first need to make the 2 haploid cells from their parents. This process is called meiosis. Meiosis is cell division where the parents split their chromosomes into a diploid cell then doing the same thing over again until it created 4 haploid cells. This will allow their offspring to receive both their parents traits.
A haploid cells are sex cells that are directly linked to the passing on their specific traits.
This is a picture is showing us both the pistil and the stamen of the flower. The stamen is used to hold the pollen grain until a pollinator comes to pick it up. While the pistil catches the grains when the pollinator comes over to the plant and then it allows the sperm inside the grain to go down the plants pollen tube.
This is an extreme close-up of the pistil (the female part of the flower). This part captures the pollen seeds that then let the sperms go into the pollen tube.
This is an extreme close up on the stamen (the male part of the flower). This is used to hold the pollen cells until a pollinator comes by and picks it up.
This is a close up on the flowers ovaries and their ovule. This is where the pollen tube takes the sperm, so that sperm and the eggs inside the varies can join together to form a gamete cell. This is located directly under the pistil.
