Natiijada casharka

Waxaad aqoonsan kartaa waxyaabaha ka falgala iyo waxyaabaha ka soo baxa photosynthesis, waxaadna qori kartaa soo koob erayo ah oo ku saabsan habkan.

Hordhac

Sideed tahay maanta? Darsigani wuxuu ka hadlayaa photosynthesis, waxaanan u baahan tahay inaad hore u ogaatid in dhirta ay cuntadooda samaystaan iyagoo isticmaalaya iftiinka qorraxda. Haddaba diyaar u noqo inaad barato waxyaabaha la isticmaalo iyo kuwa la soo saaro habkan muhiimka ah.

Muuji qoraalka

Producers make their own food using a process called photosynthesis. Photosynthesis can only happen when there is light. Photosynthesis is a series of chemical reactions that take place inside cells. The reactants of photosynthesis are water and carbon dioxide, and the products are oxygen and glucose (a carbohydrate). Photosynthesis involves many chemical reactions; a word summary of the reactants and products is a model of the process.

Imtixaannada

1. Waa **labo** shey oo dhirta ka qaato agagaarkooda iyagoo isticmaalaya **xididdada**?
- cuntada
- gaasaska hawada
- iftiinka
- Jawaabta saxda ah:macdanta (minerals)
- biyaha
2. Yaa saxan?
- **Laura:** “Dhirta uma baahna cunto – iyagu cunto bay yihiin!”
- Jawaabta saxda ah:**Aisha:** “Dhirta waa soosaarayaal (producers). Cuntadooda ayay samaystaan.”
- **Sam:** “Dhirta waa kuwa cuna (consumers) maxaa yeelay waxay cunaan cunto.”
- **Sofia:** “Dhirta waxay qaataan nafaqo (nutrients), taas oo ah cuntada oo dhan oo ay u baahan yihiin.”
3. Haddii aad fiiriso caleenta mikroskoob hoostiisa, maxaad arki lahayd?
- Jawaabta saxda ah:Caleentu waxay ka samaysan tahay unugyo badan (cells).
- Caleentu waxay ka samaysan tahay hal unug oo weyn.
- Caleentu kama samaysna unugyo.
4. Fal-galka kiimikada waxaa ku jira fal-celiye iyo wax soo saar. Waa maxay **fal-celiye (reactant)** fal-galka kiimikada?
- Wax uusan **ka qayb qaadanaynin** fal-galka kiimikada.
- Wax uu fal-galka kiimikada soo saaro.
- Jawaabta saxda ah:Wax uu fal-galka kiimikada isticmaalo.
- Wax uu fal-galka kiimikada dedejiya laakiin **aan isbeddelin** isaga.

1. Afar carruur ayaa sheegaya sababta ay photosynthesis ugu dhici waydo xididdada dhirta. Yaa sax ah?
- **Alex:** “Xididdadu waa kaliya barroosin ay ku haysato geedka meeshiisa.”
- **Izzy:** “Unugyada xididku uma baahna cunto si ay u noolaadaan.”
- **Jun:** “Xididadu waxay ka qaadaan cunto kasta oo ay u baahan yihiin ciidda.”
- Jawaabta saxda ah:**Lucas:** “Ma jiro iftiin dhulka hoostiisa si ay photosynthesis u dhacdo.”
2. Iftiinku wuxuu u gudbiyaa _____ caleemaha dhirta si ay u sameeyaan photosynthesis.
- carbon dioxide
- unugyo
- Jawaabta saxda ah:tamarta
- oxygen
3. Waxyaabaha soo socda midkee yahay **fal-celiye (reactants)** ee photosynthesis-ka?
- Jawaabta saxda ah:carbon dioxide (kaarboon laba oksaydh)
- nitrogen (nitrojiin)
- oxygen (oksijiin)
- water (biyo)
4. Maxaa dhici lahaa haddii musiibo aduunka ku riddo mugdi muddo aad u dheer?
- Dhirta waxay sii wadi lahayd inay cunto ka qaataan agagaarkooda.
- Jawaabta saxda ah:Dhirta waxay dhiman lahayd sababtoo ah cunto la'aan.
- Dhirta waxay noolaan lahayd iyagoo cuntadooda samaysanaya.
- Dhirta waxay sii noolaan lahayd waligood iyagoo biyo qaadanaya.
