Concentration Of Sucrose Affect The Growth Of Common Wheats

Introduction

I chose this topic for my experiment, because my mother has always been very interested in taking care of flowers and growing them form seeds to adults. We have many different plants in our home and every one of them has different watering and fertilizer instructions, which need to be followed in order to make the plant grow and develop as safely as possible. Every plant has unique features and appearance, which makes them intriguing. Even the individuals from one specific species can differ in size and height. Because the characteristics of every plant are unique and exceptional, they are very interesting topic to investigate. My mother’s excitement for plants also had an impact on my interest on this fascinating topic and because of this plant biology became one of the most interesting areas in biology and finally became the topic of my biology internal assessment.

My mother thought that watering
Null hypothesis
The concentration of sucrose in the soil will not affect the growth of the common wheat seeds.
Alternative hypothesis
The concentration of sucrose in the soil will affect by slowing down the growth of the common wheat (Triticum aestivum) seeds. The sucrose solution (sucrose mixed with water) added to the soil makes high concentration outside the common wheat cells and the common wheat cells become an area of low concentration. Because the osmosis is reversed, the water molecules from the common wheat cells starts to flow to an area of high concentration, in this case into the soil. The water is lost from the common wheat cells and this reduces the amount of water available for the common wheat to use in growth and photosynthesis. If the sucrose concentration is high enough, the common seeds will not be able to get water in their cells and this will cause the death of the common wheat.
