primitive life consisted of RNA,which was a self replicating molecule.RNA molecule was surrounded by a lipoprotein vesicle and formed a primitive cell,which formed proteins.then the DNA molecule was produced from the RNA molecules by reverse transcription.then DNA replaced RNA as the genetic material.Likewise the first cell was formed that was coacervaetes.
The only reason cells arise is from the division of cells or for better understanding is they come from OTHER CELLS.
Other cells. Cells cannot come into existence spontaneously.
Existing cells and other cells
cells!!!!!
Schwannomas originate in the Schwann cells
Spleen
B cells and T cells both originate from the haematopoietic (or hematopoietic) stem cells located in the bone marrow. T cells mature in the thymus. B cells mature in the secondary lymphoid tissues (such as the spleen).
Bone marrow
The beginning of time as we know it created all forms of the beginning stages and chains of life therefore creating the first cells.
All T-cells originate in the same place in humans. They originate from hematopoietic stem cells which are located in the bone marrow.

All cells originate from a previous cell, and if there is only one of them it is called the "parent cell". In the context of reproducing, the cell made from a parent cell is called the "daughter cell".
Bone marrow
what is the scientific name for the daughter cells
They both originate in the red bone marrow. B lymphocytes mature there. T lymphocytes mature in the thymus gland.
There are three kinds of blood cells, red, white, and plasm blood cells. Also called eurythrocytes, leukocytes, and thrombocytes. They all originate from a pluripotent stem cell.
Red blood cells start out in the marrow of bones. After about seven days they enter the blood stream and survive for about one hundred and twenty days.
They originate in the deepest layer of epidermis, called stratum basale. The columnar cells of this deep layer are constantly dividing to produce new cells that move outward to undergo metamorphosis at different levels.
