Answer:

b. a capsule

Explanation:

The capsule is mainly made up of polysaccharides and surrounds many bacteria. Capsule staining includes mixing of the bacterial cells with dye and spread out in a thin film on a slide. After air-drying, the cells appear as light-colored structures present in a relatively dark blue-black background. This occurs since the dye particles cannot penetrate either the cell or its capsule. Therefore, the given slide with a colorless ring around the cells in a dark background represents the presence of a capsule around the observed cells.

How are the equations for photosynthesis and cellular respiration related?
Reptile [31]

Answer:

The equation of the photosynthesis becomes reverse in the cellular respiration. In both process the reactants and products are altered.

Photosynthesis is the light harvesting process. Here the plants use water, carbon dioxide, light as raw material to produce glucose, energy and oxygen. This process occurs in the chloroplast of the leaves. In this reaction the products are oxygen and glucose.

In cellular respiration, the byproduct of photosynthesis i.e. glucose is oxidised to release energy and carbon dioxide, along with the ATP molecules. This reaction is the reverse reaction of the photosynthesis.

In cellular respiration the product of the photosynthesis becomes becomes reactant.  

The cellular respiration occurs in the cytoplasm of the cell and involves many steps to release energy. The various cellular respirations are glycolysis, kreb's cycle, electron transport chains, etc.
