What is the green pigment found in the chloroplasts of both plants and algae?
Svetradugi [14.3K]


The correct answer is A - chlorophyll.

It is a green pigment found in the chloroplasts of green plants. Chloroplasts are mostly found in the leaves of green plants and also in some algae.

Plants use chlorophyll to trap light energy from the sun. Without the light energy, plants cannot be able to carry out the process of photosynthesis, which converts water and carbon dioxide  into starch that plants use for food. 

Photosynthesis also releases oxygen which is vital for animal life.

Due to the presence of mycolic acids in the cell wall of Mycobacterium spp., the ________ staining procedure can be used as a di
UNO [17]

The question is incomplete as it does not have the option which are:

-acid-fast

-DAPI

-lipo

-Gram

Answer:

Acid-fast  staining

Explanation:

Acid-fast staining is the technique used to stain and identify the species of the mycobacterium.

During the acid-fast staining, the carbolfuchsin stain is used to color the bacteria as carbolfuchsin solubilizes the lipid of the bacterial wall and the pink stain enters the cell. When these cells are treated with the methylene blue counterstain, the mycobacterium due to the presence of thick cell wall does not allow the entry of the methylene blue as a result of which they appear red o pink.

Thus, acid-fast staining is correct.
