Chloroplasts also have a third internal membrane called the thylakoid membrane ... transport chains used in photosynthesis (Figure 2). Plant cell walls are primarily made of cellulose, which ...

Mitochondria and chloroplasts are also surrounded by membranes, but they have unusual membrane structures — specifically, each of these organelles has two surrounding membranes instead of just one.

2. The chloroplast is surrounded by a more or less permanent sheath of non-granular cytoplasm. 3. No evidence was found of the existence of an osmotic membrane around the chloroplast. 4. Certain ...

The paper focused on enzymes that help build the photosynthetic chloroplast membranes in plant cells. One of those enzymes is ...
