chlooplasts
...ns and these proteins are synthesized in the cytoplasm of the cell, but used within the chloroplast. These membranes are extremely important to chloroplasts because they control what enters the cell. This enables the cell to perform is intended functions. In the thylakoid membrane there are specific proteins that are imbedded within its membranes. The thylakoid encloses a lumen: a system of vesicles that are interconnected. Grana are the vesicles stacked on top of each other and they form assemblies of proteins, which include chlorophyll, carotenoid and ATP. Chlorophylls are classified in two types A and B. The difference between Chlorophyll A and B are their structure, where A is more complex. Chlorophylls absorb light is the red and violet parts of the spectrum and enable plants to have their green pigment. Caratenoids contain pigments that range from red to yellow and absorb light in the blue portion of the spectrum. The stroma surrounds thylakoid membranes and contains specific enzymes that are needed to carry out photosynthesis. The main function of the Chloroplast is that it plays a major role in Photosynthesis....
