need help with



what is a good conductor and a bad condutor? :?:

Well good conductors of what? Heat or electricity?
Since you in p3/p4, i assume you mean heat.

Heat conductors include metal like iron and steel.
Heat insulators include non metals like plastics, water and rubber.

Heat conductor means the material (example Steel) allows heat to pass through it easily.
Heat insulator means the material (example Plastic) does not allow heat to pass through easily.

Hi,

In primary science, students learnt that excess food is stored in different parts of plant. They are root, stem, flower and fruit.

The food in water chestnut is stored in the stem.

Another \"proof\" that the tiny food carrying phloem tubes are bi-directional.
