Hello Student
Correct answer is 2. Nucellus and Integument Tissue
Agamospermy :-Theasexualformationofembryosandseedswithouttheoccurrenceoffertilization occurs mainly in two forms
1) Gametophytic Apomixis : – The embryo arises from an unfertilized egg cell in a gametophytic that was produced from a cell that did not complete meiosis.
2) Adventitious Embryony : – An embryo is formed directly from nucellus or integument tissue.

The correct answer is (2) nucellus or integument.


In adventitious embryony (sporophytic apomixis), an embryo is formed directly (not from a gametophyte) from nucellus or integument tissue


The nucellus (plural: nucelli) is part of the inner structure of the ovule, forming a layer of diploid (sporophytic) cells immediately inside the integuments. It is structurally and functionally equivalent to the megasporangium.
