Explanation:

To solve this, we analyze the stages of female gametophyte development in flowering plants (angiosperms) as described (in Uzbek) and match with the diagram:

Step 1: Identify Stage 1

The first row (stage 1) describes the megasporocyte in the ovule undergoing meiosis: "Urug‘kurtakdagi megasporotsit hujayra meyoz bo‘linishidan so‘ng 3 ta mayda, 1 ta yirik hujayra megasporani hosil qiladi" (Megasporocyte in the ovule, after meiosis, forms 3 small and 1 large megaspore). This is megasporogenesis (meiosis of megasporocyte). The diagram’s first box (top flower/ovule) corresponds to this.

Step 2: Identify Stage 2

Stage 2: "Murtak xaltaning bir qutbida uchta, ikkinchi qutbida ham uchta, markazida esa ikkita hujayraning do‘shilishidan hosil bo‘lgan markaziy hujayra joylashgan" (From the three at one pole, three at the other, and two in the center of the haploid set, the central cell is formed). This is the formation of the 8 - nucleate embryo sac (3 + 2 + 3 nuclei, then cell formation). The second diagram box (green structure) matches.

Step 3: Identify Stage 3

Stage 3: "Urg‘ochilik gametalar gulning urg‘chi tugunchasida rivojlanadi" (Female gametes develop in the embryo sac of the flower’s ovule). This is the maturation of the embryo sac (female gametophyte) in the ovule. The third diagram box (next green structure) fits.

Step 4: Identify Stage 4

Stage 4: "Megasporotsit hujayra urg‘chining tugunchasida yetiladi" (Megasporocyte matures in the ovule’s embryo sac). Wait, correction: Actually, stage 4 is the maturation of the megasporocyte? No, re - reading: It’s the megasporocyte (wait, no, megasporocyte is stage 1; stage 4 is "Megasporotsit hujayra urg‘chining tugunchasida yetiladi" – likely the embryo sac (female gametophyte) matures in the ovule. The fourth diagram box (with multiple nuclei) matches.

Step 5: Identify Stage 5

Stage 5: "3 marta mitoz bo‘linishidan so‘ng 8 yadroli murtak xalta hosil bo‘ladi" (After 3 mitotic divisions, an 8 - nucleate haploid set is formed). This is the mitotic divisions of the functional megaspore to form 8 nuclei. The fifth diagram box (with 8 - like nuclei and central cell) matches.

To label the diagram (assuming the boxes are top - to - bottom):

1. First box (top, flower/ovule): Megasporogenesis (Meiosis of megasporocyte) (Stage 1).
2. Second box: Formation of 8 - nucleate embryo sac (nuclear divisions) (Stage 2).
3. Third box: Maturation of female gametophyte (embryo sac) (Stage 3).
4. Fourth box: Mature embryo sac (female gametophyte) (Stage 4).
5. Fifth box: Final 8 - nucleate, 7 - celled embryo sac (with central cell, egg, synergids, antipodals) (Stage 5).

If the task is to match the text stages to the diagram boxes (numbered 1 to 5 from top):

• Box 1: Stage 1 (Megasporocyte meiosis, megaspore formation).
• Box 2: Stage 2 (8 - nucleate embryo sac formation).
• Box 3: Stage 3 (Female gamete development in embryo sac).
• Box 4: Stage 4 (Megasporocyte/embryo sac maturation).
• Box 5: Stage 5 (8 - nucleate haploid set via mitosis).

(Note: The exact labeling depends on the diagram’s visual flow, but the key is matching the text descriptions to the developmental stages of the female gametophyte in angiosperms: megasporogenesis (meiosis) → megagametogenesis (mitosis and cell formation) → mature embryo sac.)
