Question

In plant cells, chlorophyll is present in
(a)Chromoplasts
(b)Stroma
(c)Leucoplasts
(d)Chloroplasts

Answer 1

Hint: Chlorophylls are some green colored pigments that give the plant leaves its color. This is essential for Photosynthesis and is vital for every living being on earth. Besides plant leaves, the algae also contain these pigments.

Complete answer:
Chloroplasts of the plant cells contain the green pigments named chlorophyll. These pigments are essential for photosynthesis as it takes the major role in absorbing the energy of sunlight. Without these pigments or chloroplasts, the leaves can not produce food and the whole ecosystem will fall apart.

Additional Information:
Let us know more about these pigments and the structures:
Along with chloroplasts of algae and plants, the green pigments are also found in the mesosomes of cyanobacteria, therefore these bacteria can also carry out photosynthesis. Without these pigments, no organism can carry photosynthesis, because these pigments only can absorb light in the blue portion of the electromagnetic spectrum, required by the process. The green portion absorbed by them gets reflected and gives the green appearance of the chlorophyll-containing parts.
Chloroplasts are the organelles of the plant leaves that contain the chlorophyll pigments that carry out Photosynthesis. Other than that, they also take part in fatty acid synthesis, amino acid synthesis, the immune response of plants, etc.
Chromoplasts also contain the chlorophyll pigments but in a very less amount than that of chloroplasts. These are heterogeneous organelles and are found in fruits, flowers, roots, and aged leaves and give them a distinctive coloration. It is because of the massive amount of carotenoids stored in them.
Leucoplasts are non-pigmented and are found in non-photosynthetic parts of the plants, mainly for the storage of starch, lipid, or protein. These are known as amyloplast, elaioplast, and aleuroplast respectively.
Stroma is nothing but a fluid-filled space in chloroplast cells that surrounds the thylakoids and grana and contains starch, chloroplast DNA and ribosomes as well as the necessary enzymes of the Calvin cycle.
So, the correct answer is “chloroplasts”.

Note: There are two several types of chlorophyll- a and b chlorophyll are found in higher plants and green algae and c and d types are found in algae and e is a rare one found in golden algae. There's a specific type of chlorophyll found in certain bacteria named bacterio-chlorophyll. The molecule of any chlorophyll is made of a central magnesium atom and a porphyrin ring surrounding it. A phytol chain is attached to this ring.
