Verb Activity
• The process of adsorb(v) light(n) energy(n) by chlorophyll(n) and transform(v) it into
chemical(adj.) energy(n) for use(v) in the Synthesis(n) of sugar(n) from water(n) and
carbon dioxide. ANSWERS
Absorbing(verb + -ing)
Transforming(verb + -ing)
Use(v)
PHOTOSYNTHESIS?
STARCH(N) IN ALL…….
LETS TEST IT!!!
PROCEDURE(n)
SAFETY: Ensure the ethanol is
keep(v) away from naked flames. Students should wear(v) eye protect(n)
when work(v) with ethanol or iodine solution. Take
care(v) with hot liquids. Be aware that plant sap may
irritate (v)the skin.
• Collection(v) leaves from the plants to be test(v).• __(prep.) your desk, pour some boil(v) water from a kettle ____(prep.) a large beaker.• Use(v) forceps, pick up one of your leaves and hold it in the hot water for about one minute.• Using forceps, remove the leaf from the boiling water and note how it has change(v).• Drop the leaf into a boiling tube and push(v) it to the bottom with a glass rod. • Put ____(prep.) your eye protection.• Add enough ethanol to cover(v) the leaf, and stand(v) the boiling tube in your beaker of hot
water, or in the hot water bath.• Watch as the ethanol boil(v) and the green colouring (chlorophyll) is remove(v) from the leaf. This
will take a few minutes.• Use(v) forceps, remove the leaf from the boiling tube and rinse (v)the leaf in cold water.• Put(v) the leaf in a Petri dish ___(prep.) a white tile.• Add(v) iodine solution to the leaf from the dropper bottle. Make sure the leaf is complete(adv.)
covered with iodine.• If starch is present, the leaf will turn(v) blue-black in colour.
