Mendel took the pollen from one pea flower and put it onto anothers pistil. In order for there to be no other pollination, he covered them with protective bags, he also moved some into a greenhouse.
The pea plants used by Mendel in his experiments were pure-breeding meaning that they only had one type of gene. The flowers of the pea plant are closed so that cross fertilization does not occur naturally. Mendel used this to his advantage, and would cut off the stamens of the plants before maturity ensuring that the plant would not self pollinate. Then, he would use the pollen from another plant to pollinate the now stamen-less plant.
In short, because the pea plant doesn't use other plants to pollinate, he was able to ensure it used only the pollen he wanted to, and had only the genes he wanted it to have.
Gregor Mendel studied pea plants. Pea flowers have both male and female organs. He removed the stamen and hand pollenated the flowers so he was sure of the cross.
If you search on cross pollination images, you will get pictures of this.
Mendel cross-pollinated flowers by removing the stamens from one of his breeding pairs (females) with a brush and then cross-pollinate with pollen from stamens (males).
He accomplished cross pollination by cutting away the pollen-bearing male parts and then dusting pollen from another plant onto the flower.
by emasculation and hand pollination
Mendel allowed the offspring of his experimental plants to self-pollinate. That is, he allowed the male and female reproductive cells of the same plant to join and produce a seed. One of the characteristics of pea plants is that it is easy to cross different pea plants but, left to themselves, they self-pollinate with little chance of any accidental pollination between plants.

Well, gregor mendel studied the heredity of living things. He used for about 28,000 pea plants to cross-pollinate and self pollinate them. He also used and made the punnet square which helped him in the first and second expiriment. In the 1st expiriment he cross pollinate two pea plants and one trait appear in all of the offspring. That was called the dominant trait and the trait that disappear was called the recessive trait. When he did his 2nd expiriment the recessive trait appear again!

I think its cross filial generation...
Peas
So that the flowers wont self pollinate.
Gregor Mendel's pea plant experiment allowed him great control, as pea plants can self-pollinate or cross-pollinate, and he was able to pollinate them at will. He studied the characteristics of each plant he would cross-pollinate, perform the pollination and plant the resulting seeds, then study the characteristics of the resulting plants.

yes
yes it is

Mendel would not have discovered the nature of simple dominance.

Gregor Johann Mendel A monk with a scientific streak, Mendel made botanical discoveries which became the basis of modern genetics. His careful cross-breeding of thousands of pea plants led Mendel to key insights, now called Mendel's Laws of Heredity, about how inherited traits are passed on from generation to generation.
