Biology Question on Kingdom Protista
Photosynthetic bacteria have pigments in
A
chromoplasts
B
chromatophore
C
leucoplasts
D
chloroplasts
Answer
chromatophore
Explanation
Solution
Photosynthetic bacteria have pigments in structures called chromatophores. Chromatophores are the extensions of cytoplasmic membranes. These are membrane-bound vesicular structures that contains photosynthetic pigments. These structures also carry electron carriers and enzymes for the process of photosynthetic phosphorylation. Chromatophores contains pigments like bacteriopheophytin and bacteriochlorophyll.
The other options are incorrect:
- Chromoplasts - These are plastids, responsible for the synthesis and storage of pigments in photosynthetic eukaryotes.
- Leucoplast - These are the colorless organelles present in plants. They are used for storage of starch or oil.
- Chloroplast - Chloroplasts are found in plant cells and act as the site of photosynthesis in plants.
