Limiting reactant is the reactant that limits the amount of a product that can be formed in a chemical reaction. For example, suppose we have 4 bolts and 8 nuts. No matter how many nuts are there, we need only 4 nuts as we have got 4 bolts. Same thing about a chemical reaction. If the limiting reactant is fully consumed, the reaction will stop even if the other reactant still remains unreacted. That reactant is called excess reactant.
Function of the Stamen. The main function of the stamen is to produce the pollen grains, which house male gametes, or sex cells, necessary for reproduction. The anther is located within the stamen where these gametes are created.lowers house the female and male reproductive structures. The female reproductive part is called the pistil and is comprised of the stigma, style, and ovary. The male reproductive part of a flower is referred to as the stamen and consists of the filament and the anther.
Parts of the Flower As the reproductive part of the plant the flower contains the male pollen and/or the female ovule plus accessory parts such as petals, sepals, and nectar glands. The pistil is the female part of the plant.
