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.

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.It is generally shaped like a bowling pin and located in the center of the flower.It consists of the stigma, style, and ovary. The stigma is located at the top, and is connected to the ovary by the style.ypes of Flowers If a flower has a stamen, pistils, petals, and sepals, it is called a complete flower. If one of these parts is missing, the flower is designated incomplete. If a flower contains functional stamens and pistils, it is called a perfect flower.
