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.

Best Answer: The pistil's function is reproduction. The stigma, the head of the pistil, provides a place for pollen grains to land and germinate.The style, the long part of the pistil, provides protection for the pollen tube that emerges from the pollen grain and grows down the inside of the pistil into the ovary.t is the female portion of the plant. So you must take a look at the three things that make up the pistill (otherwise known as carpel) and determine their function. 1. Stigma-Sticky portion at the top of the style where the pollen grains land on and germinate into a pollen tube.
