I agree with Shreya, They are talking about pollination and not dispersal. Pollination and dispersal are two different terms. If I am correct, Pollination by water occurs only in aquatic and semi-aquatic plants.

Ans 14:

Class : Class 7
yeah

Ans 15:

Class : Class 8
The answer is incorrect! Dammit1

Ans 16:

Class : Class 8
Actually, the question should be "Select the plants that are NOT pollinated by water". Vallisneria and Zostera are two plants that are aquatic, so by default their pollination is going to happen through water. All the other options are grown on land and their pollination happens through other agents. I am disappointed with SOFs repetitive errors in several worksheets and ask them to PLEASE, PLEASE rectify this error and all other errors IMMEDIATELY WITHOUT ANY DELAY.

Both options a and b are not correct as statements 1 and 4 are wrong in my opinion. In fact none of them are correct since statement 2 is the only correct statement.

Ans 8:

Class : Class 9
The answer shows d but the solution says that its c. What is this? P,ease rectify SOF.

Ans 9:

Class : Class 7
Answer should be C.When mass of an object increases, weight also increases since g (9.8 m/ses-sq) is constant and Weight = Mass x g.Hence statement (iii) is correct and hence choice C is the correct choice.Please change the answer.
