Red blood cells are carried along through veins and blood vessels throughout the body. One of their most important functions is to carry oxygen to cells, and to bring carbon dioxide (used up oxygen waste) back to the lungs to be exhaled out of the body. They also help to transport nutrients, water, and other essential items to cells and parts of the body.

What mature cells have a nucleus?
All mature cells in the human body have a nucleus, except for red blood cells. This includes cells such as muscle cells, nerve cells, and skin cells. The nucleus contains genetic material (DNA) that controls the cell's functions and activities.
Do all white blood cells retain their nucleus throughout the life of the cell?
No, not all white blood cells retain their nucleus throughout their life. Some white blood cells, such as lymphocytes and monocytes, maintain their nucleus throughout their lifespan to support their functions, while others, like neutrophils, eject their nucleus as they mature to increase their efficiency in fighting infections.
What does a reticulocyte have to do to become an erythrocyte?
A reticulocyte needs to mature by shedding its ribosomes and becoming a fully developed erythrocyte in order to function as an oxygen-carrying red blood cell. This process takes about 1-2 days in the bone marrow before the reticulocyte is released into the bloodstream as a mature red blood cell.
What is the role of the cell nucleus?
To direct all of the cell's functions.
Which animal cell does not have a nucleus?
Red blood cells do not have a nucleus. They lose their nucleus during development to make more room for hemoglobin, which allows them to carry oxygen efficiently.
What mature cells have a nucleus?
All mature cells in the human body have a nucleus, except for red blood cells. This includes cells such as muscle cells, nerve cells, and skin cells. The nucleus contains genetic material (DNA) that controls the cell's functions and activities.
Which type of blood cell looks different from cell to cell the red or white blood cells?
Red blood cells all look like red blood cells. White cells have different shapes mainly because they have different functions.
Do all white blood cells retain their nucleus throughout the life of the cell?
No, not all white blood cells retain their nucleus throughout their life. Some white blood cells, such as lymphocytes and monocytes, maintain their nucleus throughout their lifespan to support their functions, while others, like neutrophils, eject their nucleus as they mature to increase their efficiency in fighting infections.
Why organeles are not present in blood?
On the contrary, organelles are present in the blood. Blood cells are cells. All cells have organelles as they are what allow the cell to carry out its every functions.
Do brains contain hereditary information?
Yes, all cells have DNA (hereditary material) except the mature red blood cell.
What does a reticulocyte have to do to become an erythrocyte?
A reticulocyte needs to mature by shedding its ribosomes and becoming a fully developed erythrocyte in order to function as an oxygen-carrying red blood cell. This process takes about 1-2 days in the bone marrow before the reticulocyte is released into the bloodstream as a mature red blood cell.
Does a food vacuole control all functions in a cell?
No, if you had to answer what controls all functions in cell, it would be the nucleus.
What are functions that are preformed by a molecule in a cell?
cell is the basic and structural unit of our body. all the functions are performed by cell
Name one substance that a red blood cell carries?
Red blood cells carry oxygen to all areas of the body. Oxygen is vital to all of the body's organs and functions.
What is the volume of two new cells relative to a mature cell in telophase?
Each cell would be half the size of a mature cell that's ready to undergo mitosis. After all, mitosis is a process that literally splits a mature cell in two.
What part of a cell carries out all life functions?
The nucleus has DNA which has all the blueprints that direct the functions of each cell.
What is the role of the cell nucleus?
To direct all of the cell's functions.
