Mitosis and cell specialisation - OCR GatewayCloning in plants

Mitosis is cell division which produces two identical diploid cells for growth and repair. Differentiation occurs when cells become specialised. Stem cells can develop into different cell types.

Cloning in plants

Cells from meristems can be . These cells can be removed from a plant and grown in . The cells are grown in a that contains 鈥 to provide support and water for the growing cells 鈥 along with nutrients and plant to stimulate growth and cell division.

Plants are cloned to produce identical plants quickly and economically.

Producing new plants by cloning is quicker than allowing plants to reproduce then collecting and sowing seeds. It's therefore an effective way of producing new individuals from rare and endangered plants, helping to preserve the species.

Clones will also be genetically identical to the original plant providing the meristem cells. This is useful to provide crop plants for large-scale cultivation that have desirable characteristics such as disease resistance.

Tissue culture and cloning are important in growing identical plants produced by .

Cloning in plants also occurs naturally, for instance, in in strawberry plants. An older, simpler method of cloning plants that gardeners use to produce new, identical plants is by taking .
