Stem cells
Yes, stem cells are unspecialized cells that have the potential to develop into different types of specialized cells in the body. They can divide and replicate to produce more stem cells, or they can differentiate into specific cell types depending on the signals they receive from their environment.
meristem cells are unspecialized cells,similer to our own stem cells in our bones that make red blood cells.
Phloem tissue consists of: conducting cells, generally called sieve elements; parenchyma cells, including both specialized companion cells or albuminous cells and unspecialized cells; and supportive cells, such as fibres and sclereids.(attribution: wikipedia, Phloem)
All cells come from a stem cell, which is an unspecialized cell that gives rise to a specific specialized cell, such as a blood cell. These cells differentiate and give rise to the various kinds of cells we have in our body.
The correct order is as follows: Mesenchymal stem cell - an unspecialized stem cell that can differentiate into various cell types, including bone cells. Osteoprogenitor cell - a partially differentiated cell that is committed to becoming a bone cell. Osteoblast - a bone-forming cell that synthesizes and secretes the matrix of bone. Osteocyte - a mature bone cell that maintains the structure and function of bone tissue.
Meristems
They are called stem cells.
The thymus gland, it promotes the maturation of T-cells.
The thymus produces thymosin, which promotes the maturation of t cells.
You have specialized cells in your body (ostioblasts) that make bone matrix.
Yes, sponges are living organisms. They are multicellular animals that live in water and are known for their ability to filter feed. Sponges lack true tissues and organs but are still considered living organisms.
