Noun Noun 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) STARCH(N) IN ALL……. LETS TEST IT!!! 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. Investigate(n) • • • • • • • • • • • • 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. Fate of Glucose Fats CO2 + H2O Darkness(?) Starch (n) Glucose(n) ___(prep.) Green(?) Leaves • Storage • Cellular respiration • Making protoplasm (living matter) Daylight(?) Use(v) ___(prep.) tissue respiration to provide energy for cellular(?) activities Sucrose(n) Transported to storage organs e.g. Fate: An event that will happen in the future. seeds, tubers, corms. Nitrates(n) from soil and glucose make amino acids. Amino acids join to make Proteins. The important(n) of Photosynthesize(n) • Source of: • Fats(noun) • Protein(noun) • Other organic(adj.) compounds(n) Carbohydrate (Noun) Chemical Energy • Remove(n) of Carbon dioxide. (Noun) • Supply of Oxygen • Usage(v) by living organisms in respire(n). • Thus, helps in sustaining(n) of life Fossils (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.) • Coal(n) come (v) from trees(n) • Contains sunlight’s store(v) energy • From Photosynthesis(n) • Burning(v) = Energy set free…!!! • Cooking, Running Machines like Rails etc. ANIMAL FOOD PURIFICATION(N) of AIR(N) Important to IMPORTANCE Photosynthesize to PHOTOSYNTHESIS Food to FEED Direct to DIRECTLY Come to COMES Store to STORED Remove to REMOVAL Usage to USED Respire to RESPIRATION Sustaining to SUSTENANCE Vein(n) Lamina(n) Midrib(n) Stalk(n) Waxy(adj.) cuticle(n) Upper(adj.)

Epidermis(n) Structure Adaptation Large flat(adj.) surface Absorb(v) maximum(adj.) light(adj.) energy(n) Thin(adj.) Lamina(n) 1. Allows(v) CO2 – reach(v) inner(adj.) cells rapidly(adv.) 2. Enables(v) sunlight(n) reach(v) all mesophyll(adj.) cells Chloroplast(n) contains(v) Chlorophyll(n)- all mesophyll(adj.) cells Chlorophyll(n) absorbs(v) transforms(v) light energy(n) to chemical energy(n) used(v) Photosynthesis(n) More(adj.) chloroplast(n) in(prep.) upper palisade(adj.) tissue(n) More(adj.) light(n) can be absorbed(v) near(adj.) sunlight(n) Air spaces(n) in mesophyll(n) Rapid(adj.) diffusion(n) of CO2 and O2. Stomata(n) present in the epidermal(adj.) layers(n) Open(adj.) in sunlight(n), allowing(v) CO2 to diffuse(v) in and O2 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. Essential(adj.) Growth(n) Elements No chlorophyll.
