#chlorophyll

• Aeginetia — The Romanian adapted form for the plant genus Aeginetia, a category of annual or perennial holoparasitic plants in the broomrape family Orobanchaceae, native to the tropical regions of Asia. These plants completely lack chlorophyll, having leaves reduced to scales and large, tubular pink, red, or purple pipe-like flowers, extracting their nutrients exclusively from the roots of host plants (especially grasses).
• Allochlorophyll — An isomeric form of chlorophyll, obtained artificially or arising through minor chemical and structural alteration of the natural green pigment in plant or algal cells. This organic compound retains its basic properties in capturing the light spectrum, but exhibits modifications in the molecular structure of the porphyrin ring, being studied in plant physiology laboratories to understand the stability of the photosynthesis process.
• Alga — A lower, cryptogamic thallophyte plant with a body unsegmented into true roots, stems, or leaves, containing chlorophyll and other photosynthetic pigments. It lives primarily in aquatic environments or high-humidity spots. Classified into green, brown, or red variants, it plays a vital role in global ecosystems.
• Bacteriochlorophyll — A tetrapyrrolic photosynthetic pigment, structurally related to the chlorophyll of green plants, present in anoxygenical phototrophic bacteria (such as purple and green sulfur bacteria). Biochemically, bacteriochlorophyll absorbs light in the near-infrared wavelength ranges, allowing photosynthesis to occur without producing oxygen in deep aquatic environments or dark sediments.
