Difference Between Totipotency and Pluripotency in Plants

Totipotency  in Plants

Totipotency is the cell’s ability to generate all of the mature organism’s differentiated cells, tissues, and organs. Totipotent cells are found in plants and sometimes animals.

The root word “totipotent” means “having all potentialities.” Totipotent cells are cells that have the ability to give rise to all of the tissues of a multicellular organism. This is different from pluripotency, which is a property of embryonic stem cells and allows them to differentiate into any cell type in the body. Totipotent cells can develop into one or more types but not all; for example, adhesive disk tissue in plants can only form roots and disks.

Totipotency is the cell’s ability to give rise to all of the mature organism’s differentiated cells, tissues, and organs. Totipotency is not the same as pluripotency, which indicates that an embryonic stem cell will give rise to any kind of tissue or organ.

Although both are derived from totipotent cells that have committed to a particular fate in pre-embryonic development, their properties are different.

Pluripotency in Plants

Pluripotency is a term used in developmental biology to refer to cells’ ability, whether they are embryonic stem cells or skin fibroblasts, to produce any of the cell types found in an embryo. This is in contrast to cells that can produce only specific cell types.

Pluripotency in Plants is a topic of interest in developmental biology. Plants may be said to be totipotent as they are able to form an entire organism from a single cell. In comparison, animals are termed pluripotent because they are formed from the fusion of two pluripotent cells: a sperm and an ovum. Although it is unlikely that such an organism is formed, it would be totipotent.

Totipotency (and pluripotency) in plants doesn’t mean that the plant can develop into a whole new plant. It is strictly used as a method of examining the properties of cells in a developing plant. It can be used to look at the endosperm’s development in fruits such as the seedless watermelon, which can be developed without fertilization and grow into a whole pod with baby melons inside.

Difference Between Totipotency and Pluripotency in Plants

Totipotency is the cell’s ability to divide into two cells, which are genetically identical to each other and the original.  Pluripotency refers to cells that have the capacity for developing into any type of body cells, such as those found in muscles, skin, or organs.

Difference Between Totipotency and Pluripotency in Plants

The difference between totipotent and pluripotent stem cells is that totipotent stem cells can differentiate only into different tissue types from an embryo. In contrast, pluripotent stem cells can become any type of cell in the body.

In summary, 

Pluripotency is the ability for a cell to differentiate into a specialized cell from any of the three germ layers- endoderm, ectoderm, and mesoderm. Pluripotent cells are able to become any cell type in the body. Totipotency is the ability for a cell to differentiate between any of the three germ layers. Unlike pluripotency, totipotency is characteristically limited to cells in the blastula stage.
