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.

Flowers 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.elf-pollination is the more simple method, whereby pollen from the anther of a flower is transferred to the pistil of the same flower. The pollen is often transferred by falling from the anther, which is held above the pistil by the filament, down to the top of the pistil.
