Natiijada casharka

Waxaan sharxi karaa waxa walaxda hidaha tahay iyo halka ay ku kaydsan tahay xayawaanka, dhirta iyo noolaha yaryar.

Hordhac

Soo dhawoow darsiga maanta oo ka tirsan cutubka: Dhaxalka iyo DNA. Casharku wuxuu ku saabsan yahay maaddada hidaha (genetic material) iyo DNA. Kahor intaadan daawashadan bilaabin, waa inaad hore u garanaysaa in unugyadu yihiin dhismaha noolaha iyo inay leeyihiin qaybo kala duwan.

Muuji qoraalka

Plant and animal cells are made of parts including a cell membrane, cytoplasm and a nucleus. In plant, animal and fungi cells, the genetic material is stored in the nucleus. Bacteria are microorganisms and do not have a nucleus; their genetic material is stored in the cytoplasm. The genetic material of all organisms is made of a chemical substance called DNA. DNA is built from molecules that form a code used as instructions to build inherited features and control life processes

Imtixaannada

1. Waa xagee lagu kaydiyaa maadada hidaha (genetic material) unugga xayawaanka? Dooro qaab-dhismeedka saxda ah.
- Mitochondria
- Cytoplasm
- Jawaabta saxda ah:Nucleus
- Cell membrane
2. Dooro astaamaha ay leeyihiin unug kasta oo nool.
- Jawaabta saxda ah:cytoplasm (dheecaanka unugga)
- xuubka unugga (cell membrane)
- nucleus (xudunta)
- waxyaabaha hidaha (genetic material)
3. War, hadalkee ku saabsan bakteeriyada ayaa sax ah?
- Bakteeriyadu ma laha wax hidde-side ah (genetic material) maxaa yeelay ma tarmaan.
- Jawaabta saxda ah:Waxyaabaha hidde-side ee bakteeriyadu waxay ku jiraan cytoplasm-ka, sababtoo ah ma laha nucleus.
- Waxyaabaha hidde-side ee bakteeriyadu waxay ku jiraan gudaha nucleus-ka, sida unugyada dhirta iyo xayawaanka.
4. Waa maxay arrinta ku gudbisa sifooyinka dhaxalka (heredity)?
- Jawaabta saxda ah:maaddada hidaha (genetic material)
- hab-nololeedka
- deegaanka

1. Unugga bakteeriyada, meeye lagu kaydiyaa maadada hidaha (genetic material)?
- nucleus (xudunta)
- Jawaabta saxda ah:cytoplasm (sitoobaasim)
- cell membrane (xuubka unugga)
- cell wall (gidaarka unugga)
2. Shaqada DNA waa inay...
- Jawaabta saxda ah:sidato koodhka hidaha (genetic code) ee go'aamiya astaamaha la dhaxlo.
- ka tagto sawir gaar ah oo faraha ah goobta dambiga.
- laga siiyo aabayaasha ilmo si loo caddeeyo qofka aabaha ah.
