Answer 2

Lactobacilli, Tobacco mosaic virus, and rhizobium have a "Rod shape".

Lactobacillus:

• Lactobacillus is a genus of Gram-positive, aerotolerant anaerobes or microaerophilic, rod-shaped bacteria that do not form spores.
• Lactobacillus had over 260 phylogenetically, ecologically, and metabolically varied species until 2020, when a taxonomy revision classified lactobacilli into 25 genera.
• Lactobacillus species are probiotics ("good" bacteria) commonly found in humans' digestive and urinary systems.
• They can be used to treat diarrhea and "gut health."
• Lactobacillus and other "good" bacteria can assist the body in breaking down food, absorbing nutrients, and fighting off "bad" organisms that may cause disease.

Tobacco mosaic virus:

• Tobacco mosaic virus is a positive-sense single-stranded RNA viral species of the genus Tobamovirus that infects a wide variety of plants, particularly tobacco and other Solanaceae members.
• The infection generates distinctive patterns on the leaves, such as "mosaic"-like mottling and yellowing.
• Tobacco mosaic virus (TMV) is a plant virus in the Tobamovirus genus.
• The infection causes the leaves to have a mosaic-like pattern, mottling, and discoloration.

Rhizobium:

• Rhizobium is a genus of nitrogen-fixing Gram-negative soil bacteria.
• Rhizobium species associate with the roots of legumes and other blooming plants to fix nitrogen.
• Rhizobium is a soil bacteria that aid in nitrogen fixation in leguminous plants.
• It adheres to the roots of leguminous plants and forms nodules.
• These nodules fix atmospheric nitrogen and transform it into ammonia, which the plant can use for growth and development.
