OB51 distinguish between asexual and sexual reproduction in plants and describe a way in which a named plant can reproduce asexually

Sexual reproduction Asexual reproduction• involves two parent plants• a cell from each combining to produce a seed which becomes a new plant• this plant has features of both parentse.g. apple, dandelions

• involves only one parent• cells from this parent divide and a new plant grows from these cells• this plant is identical to the parente.g. strawberries, potatoes
