nucleus
Platelets are cell fragments that lack a nucleus and are key players in the blood clotting process. They help to seal off leaks in damaged blood vessels by sticking to the injured area and releasing chemicals that promote clotting.
yes
true
The concave disc shape of red blood cells maximizes the surface area of the cell, allowing for rapid movement of oxygen or carbon dioxide to and from the hemoglobin within the cell. The cell has no nucleus, and few organelles, as it does not reproduce.
blood cell? ha ha just joking. Prokaryotic cells do not have a nucleus, their genetic material is free in the cytoplasm as they do not have a need for compartmentalisation like more complex Eukaryotic cells that carry out more internal chemical mechanisms. Some Eukaryotic cells do not have a nucleus though, for example a red blood cell ejects its nucleus when mature as it no longer has a need for it and it needs as much room as possible for storing oxygen. did that answer ur question
white blood cells have a system they use to produce antibody that surrounds the cell with antibody to protect the cell from the virus by having the antibody come in the cell and kill it. But sometimes white blood cells just kill the infected cells. to make sure they don't spread.
The nucleus hangs by cytoplasmic strands in a spirogyra cell.

It Help Keep its Organelles (Cell Organs) from exiting its mass, and help in the process of osmosis.
Red blood cells contain hemoglobin, a protein that carries oxygen from the lungs to the rest of the body and carbon dioxide back to the lungs. They are also filled with enzymes and molecules that help maintain their shape and function.
