Q&A - P4 Science

Niedino:

Hi usaik,

Yes, the part you circled is the leaf. However, as you can see in the diagram, it has not fully emerged and grown fully, hence, it is unable to photosynthesize. At that stage, the plant is still using food stored in the seed leaf to germinate. Hence, (1) D only is the correct answer.

Hope it helps!

Hi smartmummy,

I would say that your child needed to add in these words to get the full marks 'Substance Q ... does not have a definite shape' To do well for the Science exams, you need to convince your child to give the full answer. One common weakness is a false sense of security, where a child thinks that his/her answer is adequate when it is not. Remind your child to imagine that the marker does not know the answer and it is his job to explain clearly.

Hope it helps!
