Question

Quantasome are present in
A) Chloroplasts
B) Mitochondria
C) Golgi Body
D) Lysosome

Answer 1

Hint: Quantasome particles are components stored within chloroplasts thylakoid membranes which is the main site for the photosynthesis to occur.

Complete Answer:
Quantasome, the components of the chloroplasts thylakoid membrane are embedded in a paracrystalline array along the surface of their thylakoid disks. The quantasomes consist of both proteins and lipids including various redox carriers and photosynthetic pigments. They are principally of two categories – small quantasomes where photosystem I takes place and large quantasomes where photosystem II takes place.

Option A: The thylakoid membranes of the chloroplasts are responsible for the secretion of quantasomes. Thus, this is the correct alternative for the given question.
Option B: Mitochondria is the energy house or the powerhouse of the cell. Thus, this is an incorrect option for the given question.
Option C: The Golgi apparatus or the Golgi bodies contributes in the transport, modification, and packaging of both the proteins and lipids for being delivered to their targeted site of action. Thus, this is an incorrect option for the given question.
Option D: The lysosomes are responsible for storing the cellular enzymes. Thus, this is an incorrect option for the given question.

Thus, the correct answer for this question is Option A i.e. chloroplasts.

Note: The function of chloroplasts is,
- They have a role in converting light energy into chemical energy.
- They help by providing various metabolic activities for plant cells - synthesis of membranes of lipids, fatty acids, etc.
