Match the following
Column-IColumn-II(i) Micropyle(a) Opposite to Micropyle(ii) Chalaza(b) Female gametophyte(iii) Embryo Sac(c) Pore of the ovule(iv) Nucellus(d) Nutritive tissue(v) Ovule(e) Integumented megasporangium(i)-(c), (ii)-(a), (iii)-(b), (iv)-(d) , (v)-(e)
Nucellus is the nutritive tissue present inside the ovule. It is the actual megasporangium which has developed from the megaspore mother cell during megasporogenesis. Hence, ovule is the integumented megasporangium. Micropyle is the apical pore through which pollen tube enters the ovule. Opposite to micropyle, the tissue connecting the nucellus and the integuments is the chalaza which forms the basal part of the ovule.
