The double membrane. It's theorized that chloroplasts used to be their own single-celled organism in the environment (and therefore with its own membrane). Then, the theory states, a larger cell took in the chloroplast by endocytosis, which involves surrounding the chloroplast in the large cell's own membrane. The chloroplast would then have two membranes surrounding it. This is similar to the thinking for mitochondria becoming an organelle as well. Hope this helps! :)
The answer would be no. T-Tubules or Transverse tubules are
additions of the sarcolemma that infiltrate into the center of cardiac and
skeletal muscle cells. There would be no functional contraction since it
would not be capable to communicate or interconnect with the other cells.
