celltype. For plantcells, enrichment with nitrogen, phosphorus, and potassium is especially important. Water is provided as a constituent part of the gel media.
A plantcell callus consists of somatic undifferentiated cells from an adult subject plant.
A callus is not necessarily genetically homogeneous because a callus is often made from structural tissue, not individual cells. Nevert

But no, human cloning is real.
One benefit of human cloning is that it will allow scientists to better understand cell
differentiation. Research on the basic processes of cell differentiation can lead to dramatic mew
