Question

The photosynthetic unit having 250 chlorophyll molecules is called
A. Photon
B. Quantum
C. Quantasome
D. Oxysomes

Answer 1

Hint: Chlorophyll is a type of pigment present in all green plants and in some other organisms, which helps in the photosynthesis reaction of the plant. Chlorophylls absorb sunlight and later it converts into chemical energy. Due to its pigmentation, the color of the leaves become green.

Complete answer:
Photosynthesis is a process executed by all green plants and some other organisms in the presence of light. In this process phototrophs, i.e green plants used to convert light energy to the chemical energy and store the energy for the purpose to release it when it is required to perform the various metabolic reactions. In the daytime, the green plant performs this process by absorbing carbon dioxide from air and water from the soil through the root.
The photosynthesis process occurs in the chloroplasts with the help of some photosynthetic pigments such as chlorophyll a, chlorophyll b, carotene and xanthophyll.
Chlorophyll is a type of green pigment that is present in the chloroplasts of algae and plants and the mesosomes of cyanobacteria. Chlorophyll is essential in photosynthesis, as it is mainly responsible for absorbing the energy from the sunlight.
A photosynthetic unit is a complex form of pigments and proteins which is found in the centre of the reaction where the initial stage of reaction takes place. Quantasome is a type of photosynthetic unit which contains 230-250 chlorophyll molecules. The photosynthetic unit containing about 250 chlorophyll molecules is referred to as quantasome which was invented by Park and Biggins. In the thylakoid membrane of the chloroplast of plant cells, the quantasome is located. The quantasome is the form of proteins and lipids. In the quantasome, several types of enzymes are also present which is required for the process of photophosphorylation. It formed two types of photosystem or pigment system which is known by PS1 and PS2.

Hence, the correct answer to the question is option C.

Note: Photosynthesis is a type of reaction which is essential to produce the energy in a plant. In this process, light energy from the sun is transformed into chemical energy. This process is performed by the chlorophyll which presents in the chloroplast of the plants. This chlorophyll mainly absorbs light. Generally 230-250 chlorophyll present in the photosynthetic unit quantasome.
