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.
The pollen created by the anther is often sticky so that it attaches to pollinators and is passively transferred between plants. After pollination, the pollen grain that is now attached to the stigma at the top of the pistil will begin to burrow a tunnel through the length of the style to get to the ovary.
