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)
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. Investigate(n)
Fate of Glucose Fate: An event that will happen in the future. Starch (n) CO 2 + H 2 O ? Fats Storage Cellular respiration Making protoplasm (living matter) Use(v) ___(prep.) tissue respiration to provide energy for cellular(?) activities Glucose(n) ___(prep.) Green(?) Leaves Sucrose(n) Transported to storage organs e.g. seeds, tubers, corms. Nitrates(n) from soil and glucose make amino acids. Amino acids join to make Proteins.
The important(n) of Photosynthesize(n) Carbohydrate (Noun) Source of: Fats(noun) Protein(noun) Other organic(adj.) compounds(n) Chemical Energy (Noun) Sunlight(n) = Ultimate(adj. source(n) of radiant(adj.) energy. Converted(v) to chemical(adj.) energy(n) in Carbohydrates(n) Animals(n) food(v); gain(v) energy direct (adv.) Fossils (Noun) Coal(n) come (v) from trees(n) Contains sunlights store(v) energy From Photosynthesis(n) Burning(v) = Energy set free…!!! Cooking, Running Machines like Rails etc. Eventually (adv.) becomes(v) Helps (V) PURIFICATION(N) of AIR(N) Remove(n) of Carbon dioxide. Supply of Oxygen Usage(v) by living organisms in respire(n). Thus, helps in sustaining(n) of life

Stomata(n) present in the epidermal(adj.) layers(n) Open(adj.) in sunlight(n), allowing(v) CO 2 to diffuse(v) in and O 2 to diffuse(v) out. Veins(n) contain(v) Xylem and Phloem.Xylem(n): transports(v) water and Minerals to mesophyll cells. Phloem(n): transports(v) sugars away from leaf. Petiole (n) (leaf stalk)Holds(v) leaf(n) in position to absorb(v) maximum(adj.) light energy.
