During sexual reproduction in flowering plants, the male gametes are carried inside (1) ______________ grains. These grains are produced in the (2) ______________ of the stamen. To reach the female reproductive organs, they must be transferred to the (3) ______________ of a carpel during a process called (4) ______________.

Following this transfer, a tube grows down the style into the ovary. The male gamete enters an (5) ______________ , where it fuses with the female gamete, the (6) ______________ . This fusion, known as (7) ______________ , forms a single diploid cell called a (8) ______________ .

This diploid cell begins to divide by (9) ______________ to form a multicellular embryo, while the surrounding outer structure of the ovule hardens to become a (10) ______________ .
