It is a double-membrane structure in which the outer membrane is more permeable than inner membrane. The inner membrane possesses more proteins. The outer membrane may be attached to ER. They are present in the cytoplasm of green algae and higher plants. Based on the given information, answer the given questions
Name the given structure

Explanation

**Step-by-Step Solution:**

1. **Identify the Structure**: The question describes a double-membrane structure. The outer membrane is more permeable than the inner membrane, which is a key feature to note.

2. **Membrane Characteristics**: The inner membrane contains more proteins, indicating that it may have specific functions related to transport or enzymatic activity.

3. **Connection to Other Organelles**: The outer membrane may be attached to the endoplasmic reticulum (ER), which is significant as it suggests a close relationship between these organelles.
