Mavzu: Turning morfologik mezonlarini o'rganish
Maqsad: Ta'lim muassasalari atrofida keng tarqalgan ikki xil tur yoki uning gerbariysi, yoki kolleksiyasidan foydalanib turning morfologik mezoni bilan tanishish. turga xos morfologik belgilarni aniqlay olish, morfologik mezonga ko'ra individlarning bir turga yoki har xil turga mansubligini aniqlash.
Jihоzlаr: 2 ta turga mansub o'simliklarning 3-5 tadan gerbariysi yoki tirik na'munalari.

Ishni bajarish tartibi:

1.O'simlik na'munalarini diqqat bilan o'rganing.
2.O'simliklarni morfologik mezon asosida turlarga ajrating.
3.Har bir turga morfologik tavsif bering.
4.Har bir turga mansub o'simliklarning ildizi, poyasi, bargi, gulkosa, gultojbargi, mevasining shakli va rangiga e'tibor bering?
5.O'simlik tipidagi gul va mevalar soni, ularning rangi va shakliga ahamyat bering.
6.Jadvalni to'ldiring:

Xususiyatlar	1-o'simlik turu	2-o'simlik turi
O'simlik nomi
Sistematikadagi o'rni
Ildiz sistemasi turi
Bargi oddiy yoki murakkab
Barglarining tomirlanishi
Bargning poyada joylashuvi
Poyasi o't yoki yog'och
Poyasining fazoda joylashuviga ko'ra turi
Gulqo'rg'oni oddiy yoki murakkab
To'pguli
Mevasi

7.Nima uchun organizmlarning qaysi turga mansubligini aniqlash uchun barcha mezonlardan foydalanish zarur? Nima uchun morfologik mezon turlarni aniqlashda asosiy o'lchov bo'la olmaydi?
8.Morfologik mezonning nisbiy ekanligiga misollar keltiring?
9.Kuzatganingiz asosida xulosa chiqaring?
