Plant cells are also surrounded by a relatively tough but elastic wall. It is known that each and every plant cell possesses a definite cellulosic cell wall and the protoplast lies within the cell wall except some reproductive cells and the free floating cells in some fruit juices like coconut water. Nowadays, we know that the cytoplasm is very complex and that it contains intricate organelles. It is where the organelles with various essential functions are found. [3] In the case of plant cells, protoplasts may be regenerated into whole plants first by growing into a group of plant cells that develops into a callus and then by regeneration of shoots (caulogenesis) from the callus using plant tissue culture methods.
