Red blood cells carrie oxegen to the different parts of your body allowing you to function and live.
The outermost layer of cells in an onion, the epidermis, forms a protective barrier against environmental stresses. The arrangement of cells in multiple layers allows for strength and flexibility, providing support to the parts underneath. Additionally, specialized cells called sclerenchyma cells provide extra structural support to the onion.
provides protection from harm
the reason you wouldn't see chloroplasts is because the onion root tip is underground where light can not reach and why would it need chloroplasts if it didn't need to produce energy form light?
All organisms are made of cells. An onion is and organism, hence all parts of an onion are made of cells.

Blood cells are cells. They are found in your circulatory system. Red blood cells are red and carry oxygen to your body parts. White blood cells fight infection and disease.
Red blood cells carrie oxegen to the different parts of your body allowing you to function and live.
The parts of the blood are the formed elements (solid parts) and the plasma (the liquid in which the solid parts are suspended). The formed elements include red blood cells, white blood cells, and platelets.
The onion cells are much more rectangle shaped, than the cheek cells and the nucleus in the onion cell is much more bigger and better seen in the microscope.
Four of the most important ones are red cells, white cells, platelets, and plasma.
In a normal drop of blood you will find red blood cells, white blood cells: Neutrophils, lymphocytes, eosinophils, basophils and platelets (not cells, but parts of megakaryocytes - cells formed in the bone marrow).

Lysosomes are organelles found in animal cells that serve to break down food and also recycle other cell parts. They are not present in blood cells.
