Can someone help to explain the Q17? Answer key is 2.
Thanks.

Hi
Answer key is wrong.Answer should be 1.Look at cell d closely.You would observe it also has a regular shape.Cell B is a plant cell taken from the aquatic plants.Cell a has the same features as cell d.Therefore,all options except option c,in which the cell is irregular,is considered the answer.

Hi
I am not going to tell all the answers.Use the strategy that i taught you.Find the topic and the concept of the question.For the circuit question,trace the electricity path of each option.
For each question,you tell me the topic and the concept.Once i correct it,you could find the answer.
Cheers

Ok, but do correct my answer later in my post, because I am going to check.

Hi

Yes.Onion does reproduce by buds.But i think they should put 'reproduce by buds instead of the'reproduction in seeds'.But this does not affect the answer.Your understanding is correct.
cheers

Thanks

reproduction by other plant parts is not in syllabus anymore

Can help to explain this question? Thanks. My DD told me the answer should be 1 since 1 has the biggest surface area. :imdrowning:
