Blood cells resemble unicellular organisms due to the similarities in their functions. They are all single, separate cells with specific functions that can freely move.
they can divide and are also made of the same components
they are small and oval shape
These single celled organisms are called prokaryotes.

This is a good time for "Yes... and no." It all depends on the type of organism.In animals, which should be the both of us (If you are a human :) all cells are generally the same size. Of course, cells like nerve cells and muscle cells might not count in the reason that they can stretch to be relatively large or be the same size as other cells. For the most part, the same types of cells (i.e. bone cells, skin cells, blood vessel cells, eye cells) are the same size even in different animals. Small animals like bugs have the same size cells as larger animals like elephants or whales or birds.Bacteria though, and other single celled organisms, have cells much smaller than animal cells. In fact, more bacteria cells are present in the human body than animal cells! So, the cells of single-celled organisms are much smaller than those of multi-celled organisms. In animals, small and large have about the same size cells.
cells in a multicellular organism have the ability to specialize in certain functions for the overall success of the organism. some genes will be expressed in some cells while other genes in other cells. this creates the difference between skin cells versus liver or blood cells. a unicellular organism must cover all the functions of an entire organism and all the necessary genes must be expressed plus all the functions of created and breaking down compounds necessary for growth, development and producing offspring.
They generally consist of only one cell (!)Above that I cant give you a better answer as there is such variety in unicellular organisims. Bacteria (and all prokaryotic life), single celled eukaryotes such as amoebia, white blood cells and fungus to name the main offenders.To keep it general all single celled organisms must be able to reproduce, sustain their life and consist of one cell. The reason viruses are not classed as living organisms is that they are unable to reproduce without invading it's host and hijacking their reproduction machinery.
These single celled organisms are called prokaryotes.
Your blood is not single-celled, is is muti-celled because all of the red blood cells in your blood.
Protists are single celled organisms. They include water borne contamination. Protists are, eukariotic, single celled organisms. Paramecium, amoeba are protists
A single celled organism has ONE cell to do everything - breath, eat, excretion of wastes and other functions that organism does. Multi-cellular organisms have specialised cells for certain functions. For example, TWUNNY WUN.
Larger bacillus. Multi-celled organisms. White blood cells.
A white blood cell is not an organism because it cannot live separately from the rest of the cells making up a human being. It is, however, similar to single-celled organisms like amoebae.
Cells come in many forms, including: -Red blood cells inside our bodies. -Single-celled organisms. -Spores from fungi.
capillaries are microscopic blood vessel that have single-celled walls.
Because an amoeba is a single celled organism and single cells do not contain blood (which is itself made up of millions of cells).
Unicellular organisms usually come from Protista kingdom, but in order for them to reproduce and survive there is a nucleus of course. im not aware of any exceptions though. Well if i could answer ur question i'd say animalia , without being 100% correct. animals have red blood cells! (anucleated cells!)
Single-celled organisms like the amoeba are neither coldblooded nor warmblooded because they don't have blood. The cell absorbs its nutrients and excretes its waste products directly through its cell wall into the environment. Complex multicellular organisms need a means of moving food in and waste out and so developed blood as a transport mechanism.
