Correct Answer: E
Solution :
Ovule is an integumented megasporangium food in spermatophytes which develops into seed after fertilization. In most plants belonging to the sympetalae with unitegmic tenninucellate ovules, the nucellus degenerates at an early stage of ovule development and the innermost layer of integument becomes specialised to perform the nutritive function for the embryo sac. This specialised tissue, present on either side of the embryo sac, is called endothelium.
