The bacterium used in the production of acetic acid (vinegar) is: MCQ with Answer and Explanation

Explanation:
Rhizopus stolonifer belongs to the class Phycomycetes (or Zygomycetes). These fungi are characterized by a coenocytic (multinucleate, aseptate) mycelium and reproduce asexually by forming motile or non-motile spores in sporangia. Ascomycetes (sac fungi) have septate hyphae and produce ascospores in asci. Basidiomycetes (club fungi) produce basidiospores on basidia. Deuteromycetes are imperfect fungi lacking a known sexual stage.

Explanation:
Lysosomes contain hydrolytic enzymes that can digest cellular components and even the whole cell if they burst, a process called autolysis. Hence, they are called suicide bags. They also perform autophagy and phagocytosis. Peroxisomes detoxify peroxides, Golgi modifies proteins, ribosomes synthesize proteins. Lysosomes are formed from the Golgi apparatus.

Explanation:
Cyanobacteria contain chlorophyll a (like plants) along with phycobilins (phycocyanin and phycoerythrin). Chlorophyll b is in green plants, phycocyanin is an accessory pigment.
