ABSTRACT

This research paper reviews the contribution of photosynthesis and how it is very important to plants. It also examines the relationship between chichorium intybus and spinacia oleracea chloroplast absorbency levels.Photosynthesis is a very important part for plants. Photosynthesis is what allows plants to survive. It provides ATP were it can be used for energy. In them it consumes Carbon Dioxide to produce Oxide. The Chlorophyll in the chloroplasts of a leaf are responsible for absorbing wavelengths of light. This paper also mentions how light is used to synthesize organic molecules? This question was answered by basing of how their are many leafs with different colors. The reason being that chlorophyll is the main pigment at work in green plants but there are other pigments conned in the chloroplasts of purple plants. Because there are other pigments that are at work in the leaves of purple plants the chloroplasts will have different spectrums of absorbance when compared to the leaves of the green plant. From gathering all this information it was theorized that because green leaves absorb light poorly at green wavelengths, the purple lights will absorb poorly at violet wavelengths. In theory, the pigment should reflect its own color and absorb the other wavelengths well, like we see with the chloroplasts in green spinach leaves. The experimental strategy was to use chichorium intybus plant for this experiment . Follow the same protocol from the previous experiment except green leafs wouldn't be tested on. The chloroplasts will then be isolated and the absorbance will be determined by the various wavelengths of light.

INTRODUCTION

Photosynthesis is a highly required multistep process needed for plants to survive. Photosynthesis takes place inside the chloroplasts which contain a green substance called chlorophyll. Because of chlorophyll chloroplasts is capable of absorbing light energy for photosynthesis. Another way photosynthesis can be looked at is by viewing it as its overall reaction: 6H2O + 6CO2 + light → C6H12O6+ 6O2. ( Six water molecules + 6 carbon dioxide molecules + light is converted into one glucose molecule and six oxygen molecules). Photosynthesis is the conversion of light energy into chemical energy by living organisms. Photosynthesis is the process by which plants and some bacteria use sunlight to produce sugar which cellular respiration converts into ATP were its used for energy. Photosynthesis is not the only process plants undergo. Another step plants undergo are pigments which are chemical compounds that reflect only on certain wavelength of visible light. This is why there are so many plants with different colors. Since pigments interact with light and absorb at certain wavelengths pigments are useful to plants and other autotrophs.There are three different pigments Chrophyll, Carotenoids and Phycobilins. Chlorophyll is a greenish pigment which contain a porphyrin ring. This ring is a stable ring molecule which allows electrons to move freely. Making the ring have the potential to gain or lose electrons easily and thus making it potential to provide energized electrons to other molecules.Carotenoids are usually red, orange or yellow pigments. Carotenoids cannot transfer sunlight energy directly to the photosynthetic pathway but must pass their absorbed energy to chlorophyll.Phycobilins are water soluble pigments and are therefore found in the cytoplasm or in the stroma of the chloroplast. As for this experiment the levels of chloroplast of chichorium intybus is being compared with spinach leaves as the control. This second experiment was based on the resources found. For instance Chloroplasts exist in plants cells and absorb certain wavelengths of light. And this can be proven from the previous experiment that was conducted which was
