- Blood is a connective tissue in animals and is composed of cells (like red blood cells, white blood cells) suspended in plasma.
- Water is a chemical compound ($H_2O$) and has no cells.
- Carbon dioxide ($CO_2$) is a gas and a chemical compound with no cells.
- A chromosome is a structure within a cell (made of DNA and proteins) and does not contain cells itself (it is part of a cell).
So, blood is the structure that contains cells.
