because in the stem there are special vessels (xylems) that carry the water and glucose from the roots and leaves of the plant.
no
The use of stem cells is not unethical in and of itself, the ethics component revolves around the source of the stem cells and the concern that fetuses will be produced and intentionally destroyed in order to obtain stem cells.
Red blood cells are produced by stem cells in bone marrow.
basal stem cells.
Hematopoietic stem cells are the parent cells for all formed elements of blood, including red blood cells, white blood cells, and platelets. These stem cells have the ability to differentiate into various specialized blood cells through a process called hematopoiesis.
lymphocyte counts
There are three types: totipotent, multipotent, and pluripotent. Totipotent: cells produced from the fusion of an egg and a sperm (embryo) Multipotent: cells that can give rise to a small number of different cell types--for example, bone marrow and brain contain this type Pluripotent stem: this type can produce almost all type of cells in the body; called 'true' stem cells I know there are Endothelial Progenitors, Germline Stem Cells, Hematopoietic Progenitors, Mesenchymal Stem Cells, Neural Stem Cells, Signaling Pathway, Embryonic Stem Cells, Cancer Stem Cells and Stem Cell Cytokines.

There are five basic stem cells classifications there is embryonic stem cells, fetal stem cells. There are the Umbilical cord stem cells, placenta stem cells, and lastly there are adult stem cells.
T-lymphocytes are produced in the bone marrow from hematopoietic stem cells. They mature in the thymus, hence their name "T cells."
During primary growth of the stem, new cells are produced in the apical meristem located at the tip of the stem. These cells differentiate into various types of tissues, such as epidermis, cortex, and vascular tissues, allowing the stem to increase in length. The elongation of cells in the stem is mainly due to cell division and expansion.
