The Many Causes of Fatigue. Fatigue is mainly a symptom and not a disease in itself. The key is for the doctor, with the patient's help, to discover the underlying cause of fatigue.
Chlorophyll is vital for photosynthesis, which allows plants to absorb energy from light. Chlorophyll molecules are specifically arranged in and around photosystems that are embedded in the thylakoid membranes of chloroplasts. In these complexes, chlorophyll serves two primary functions.hlorophyll is vital for photosynthesis, which allows plants to absorb energy from light.

  Chloroplast are organelles found in plant cells and other photosynthetic eukaryote organisms. Chloroplasts get energy from the sun and use it to make food and to produce â¦ ATP to use by animals and other consumers. Chloroplast have chlorophyll which gives plants their green color.he chloroplast is the organelle that contains the photosynthetic  pigment chlorophyll. This facilitates the conversion of carbon  dioxide, water and sunlight into sugars wh â¦ ich the plant uses for  energy (through photosynthesis).
