Q&A - PSLE Science

Hi meimeitan


You may end up with different answer depending on the grouping.

If you use natural material instead of man-made as the group heading, then disposable cup is the odd one out. That is assuming disposable cup is made of man-made material.

Is your question from past years papers?

I think the heading cannot be \"natural material\" because there will be overlap as \"from animal\" and \"from plant\" may also be classified as \"natural material\".

A general question here:

Where are the stomata found on the leaves of water plants? Are they still found mainly on the underside of the leaves?
WHY ?
Thank-you.

Cheers,
Belle.

Hi Belle2011


Stomata are openings in leaves which allow for gaseous exchange. For water plants like water lilies, stomata are found on the upper sides of leaves, where they are exposed to the surrounding air.

Please check with your school teacher if the topic on stomata in aquatic plants is covered in PSLE science syllabus.

Dear all,


How do money plants adapt themselves to grow upwards to get sunlight to carry out photosynthesis?
(a) They have woody stems
(b) They twine round supports
They have tendrils to help them climb
(d) They have roots to help them climb.

Thank-you.

Cheers,
Belle

Hi

I am more inclined to go for option (d) ----- They have roots to help them climb.

Dear tianzhu,
Yes, the model answer is (d).

What is the meaning of \"having roots to help them climb\"? I thought money plant seems to be able to stand alone and unlike those with weak stems which need to twine around supports or have tendrils to help them climb?

Thank you very much for your advice.

Cheers,
Belle

Hi Belle


I think you’re referring to those decorative money plants in pots found on tables in many houses.

When I was a young boy many years ago, I saw money plants climbing on fences in the kampong I lived in.

Please refer to page 8 and 9 of this link.

Dear tianzhu,
Thanks for sharing the website. Guess the materials involved are way beyond PSLE level but good to read for info.
Thank-you.

Cheers,
Belle.

Hi Belle

Good Morning

If I remember correctly, there are some information on money plants in primary science textbook and guidebooks.

Have you tried reading your science guidebooks from MC and EPH?

I think adaptation of climbing plant ( weak stems) is covered in PSLE science syllabus.
