INTRODUCTION

A. Background of the Study
Philippines is an agricultural country. The geographical location of this country in the Tropic plays the major role to this fact. Aside from rice, Filipinos produce most of the crops that they use to make food that they serve in their dining tables. In the countryside, houses have different kinds of vegetables, fruits and root crops planted on their backyards. Unfortunately, people living in urban places don’t have backyards. There are a few plants that will grow with only one light in a windowless office or a one-room apartment whose single window faces into an air shaft. (House Plants, 1975)
Artificial lighting is the answer for almost any kind of plant that can be grown if enough artificial light is provided, even in situations where no other light is available. Artificial lights allow regular people to plant whole gardens in places where no plant would ordinarily grow.
A lesson in cell metabolism-energy and photosynthesis mentions that “chlorophyll absorbs most red, orange, blue, and violet light. It reflects green and yellow light, giving its body a green coloring”. This statement got the researchers curious and wondered if plants act differently to the green and yellow colors of light, then they should have different reactions and effects to every color of light. (Capco C., Yang G., 2010).
This study aimed to find if there exist a significiant difference in the growth of plants when exposed to different colors of light specifically red, yellow, green, blue, and white. In this case, the researchers chose the mongo plant since it grows quickly and the researchers can quickly gather the needed data immediately.

B. Statement of the Problem
This study determined and compared the effect of different colors of light on the growth of mongo plants. Furthermore, it addressed the following
