Subject :NSO    Class : Class 7

The following investigation was carried out using flower buds growing on three plants of the same species :
Plant 1 – The anthers were carefully removed and the buds left open to the air.
Plant 2 – The anthers were left untouched and a paper bag was tied tightly around each bud.
Plant 3 – The anthers were carefully removed and a paper bag was tied tightly around each bud.
All flowers were opened normally but only those on plant 1 produced seeds.
What can be inferred from it?

A Only cross-pollination can take place in this plant species.
B Only wind-pollination can take place in this plant species.
C Only insect-pollination can take place in this plant species.
D Both self and cross-pollination can take place in this plant species.

So, both forms of pollination can happen. Hence the answer should be D.

yes but they are talking about the species, not that particular plant. It's anthers were removed but it still gave fruit which means the flower is bisexual.

Ans 4:

Class : Class 8
There used to be anthers so it is D

Ans 5:

Class : Class 7
Answer should be D or options should have been framed better.
