Question

Which of the following specialized structures/inclusions would aquatic photoautotrophic bacteria likely possess? 1. Thylakoids 2. PHB Granules 3. Carboxysomes 4. Gas vacuoles 5. Chloroplasts

Answer 1

Answer:

1. Thylakoids 2. PHB Granules 3. Carboxysomes

Explanation:

1. Thylakoids are membrane bounded compartments present in bacteria for light dependednt reactions.

2. PHB Granules help in carbon fixation

3. Carboxysomes help to retain carbon when enough supply isn't available.

Answer 2

Answer: Option 1,2 and 3.

Thykaloids, PHB granules and carboxysomes.

Explanation:

Carboxysomes consist of polyhedral protein and enzymes Rubisco which is important to supply carbon and fix it.

Thykaloids are membrane bound part of chloroplast which is the site of light dependent reaction during photosynthesis.

PHB granules are important component which help to fix carbon .
