Read the following features of a specific cellular structure: Membrane 'M' is a component of a double-membrane bound organelle and is relatively less permeable. The compartment 'Y' enclosed by membrane 'M' contains enzymes required for the synthesis of carbohydrates and proteins, along with 70S ribosomes. Identify membrane 'M' and compartment 'Y'.

Step-by-step solution

According to NCERT, chloroplasts are double-membrane bound organelles. Of the two membranes, the inner chloroplast membrane is relatively less permeable. The space limited by the inner membrane of the chloroplast is called the stroma. The stroma contains enzymes required for the synthesis of carbohydrates and proteins, as well as 70S ribosomes and circular DNA. The inner mitochondrial membrane encloses the matrix, but the matrix does not primarily synthesize carbohydrates. The outer chloroplast membrane is more per
