_______ is the arrival of pollen on a receptive stigma.

Concept introduction:
A flower is the reproductive part of the modified thick shoot of an angiosperm plant. The transfer of pollen from a male part to the female part of a plant allows the fertilization to occur and later develops into a seed. Pollination takes place with the help of pollinating agents such as wind or animal.
Answer to Problem 1SQ
Correct answer: Pollination is the arrival of pollen on a receptive stigma.
Explanation of Solution
In the flowering plants, pollination is one of the necessary processes for sexual reproduction. Pollination involves the arrival of pollen grains on a receptive stigma. The flowers containing both carpels and stamens are called perfect flowers and they can pollinate themselves. On the other hand, the flowers which don’t possess the carpels and stamens are called imperfect flowers and do not pollinate themselves.
