The answer is the second one: chloroplast.

Explanation:

  • Chlorophyll: This is a photosynthetic pigment found in plants, algae, and cyanobacteria. It plays a crucial role in absorbing light, primarily in the blue and red wavelengths, and is essential for the process of photosynthesis.

  • Chloroplast: This is not a pigment but an organelle found in plant cells and some algae. Chloroplasts contain chlorophyll and other pigments, and they are the site where photosynthesis takes place.

  • Carotenoid: This is a class of pigments found in plants, algae, and photosynthetic bacteria. Carotenoids absorb light in the blue and green regions and contribute to photosynthesis by passing absorbed energy to chlorophyll.

  • Phycobilin: This is a photosynthetic pigment found in cyanobacteria and certain algae. Phycobilins absorb light in the orange to red wavelengths and are involved in capturing light energy for photosynthesis.

In summary, chloroplast is not a photosynthetic pigment; it is an organelle that contains pigments like chlorophyll and carotenoids.
