Question

Which of the following cellular structure contain pigments?
A) ER, golgi body, chloroplast
B) Vacuole, chromoplast, chloroplast
C) Chloroplast, chromoplast, leucoplast
D) Chloroplast, mitochondria, nucleus

Answer 1

Hint: The presence of cellular pigment is one of the characteristics of plants. The plants have green colour pigment chlorophyll present in the leaves which helps in synthesising food through photosynthesis. The several other colour pigments are responsible for the colour of fruits, flowers.

Complete answer:
The pigments are the biological pigments that are most essential for the photosynthesis in plants. The different colour pigments absorb the light of various colours and reflect others. The pigments are present in the cellular organelles like plastids. Chloroplast is one of the important cellular organelles (type of plastid) in the plant cell which contains chlorophyll that is a green colour pigment that is responsible for photosynthesis.

The other pigment-containing organelles are chromoplast- They also type of plastids which is responsible for the colour of fruits, flowers. They are responsible for the synthesis and storage of carotenoids.
The vacuole is the storage organelles in plants. They contain anthocyanin which provides red and blue colour to the fruits and flowers. (option B correct)

The other type of plastid is leucoplast. They are colourless and is responsible for the storage of oil. (option c is incorrect)

The endoplasmic reticulum is found in the eukaryotic cell. The function is to transport proteins. Golgi bodies- Saclike structure containing flattened sacs. They are responsible for the sorting of biomolecules. Option A incorrect.

Mitochondria- It is known as the powerhouse of the cell. It produces ATP. It has its own genetic material.

Nucleus- It is the principal organelle of the cell which contains the genetic material. It is responsible for controlling the physiology of the cell. (option D is incorrect)

Therefore the correct answer is option ‘B’.



Note: Some of the prokaryotic bacteria also have chloroplast. So they can perform photosynthesis. The chloroplast is embedded in the plasma membrane so that it can perform photosynthesis. In the case of eukaryotes, the chloroplast is present in the cytoplasm.
