Yes, all cells contain DNA because it is necessary for life. DNA codes the RNA which makes the proteins that determine essentially ever characteristic of an organism and the parts of the cell. Tissues are made of cells, so the individual cells contain DNA. Note: in prokaryotic cells, the DNA is not contained in the nucleus, but they DO have DNA, it just floats around freely in the cytoplasm.
You would expect to find numerous gap junctions in cardiac muscle tissue, as they allow for rapid electrical communication between cells, coordinating the contraction of the heart.
You would expect to find a high concentration of mitochondria in cells that require a lot of energy, such as muscle cells and nerve cells.
Chloroplast
no. muscle is animal tissue
Chloroplasts, and a cell wall.
Yes
Not in the leaves
Chloroplasts, and a cell wall.
Brain and the spinal cord.
In the stele, which is the central cylinder of vascular tissue within the root.

cells would be specialized to expand and contract
