Mitochondria and chloroplasts are organelles of a cell possess their own DNA. Thus, option (b) is correct.
In both plant and animal cells, mitochondria are membrane-bound organelles that are essential for producing the chemical energy required for the cell's metabolic processes.
On the other hand, chloroplasts, which are only present in plant cells, are in charge of photosynthesis. Both organelles are involved in protein synthesis and have their own genetic material.
As a result, the significance of the organelles of a cell possess their own DNA are the aforementioned. Therefore, option (b) is correct.

cell membrane?
Answer:
Water channel proteins are helps the molecules move through a cell membrane.
Explanation:
this protein acts like a pore in the membrane that lets water molecules or small ions through quickly. This proteins (aquaporins) allow water to diffuse across the membrane at a very fast rate. Ion channel proteins allow ions to diffuse across the membrane.
Answer:
Gated Channel protein
Explanation:
The parasympathetic nervous system is most likely to be dominant while someone is napping after a big meal?
The cell membrane has two functions and one is a barrier keeping the constituents of the cell in and unwanted substances out and, second, to be a gate allowing transport into the cell of essential nutrients and movement from the cell of waste products.
