2. What is the function of ovary?

• It connects stigma to the ovary

• It contains the ovules

• It recieves pollen grains

3. "Transfering pollen grains from the anther to stigma" is the process of ....

• pollination

• fertilisation

• dispersal

4. Observe the following statements! Arrange the statements below based on the process of fertilisation correctly.

1. Pollen grains land on the surface of stigma,

2. The tube grows down from the stigma, through style to the ovary,

3. Each pollen grains produces a pollen tube,

4. When pollen tube reaches the ovules, the male reproductive cell in pollen tube fuses with the egg cells
