Understanding Plant Germ Cell Fusion

The question asks for the immediate outcome when male and female germ cells fuse in plants. This fusion process is known as fertilization.

Fertilization in Plants

• Fertilization occurs when the male gamete (from the pollen grain) successfully fuses with the female gamete (egg cell) located inside the ovule.
• This fusion combines the genetic material from both parents.

Result of Fusion: The Zygote

The Zygote is the single diploid cell formed immediately after the fusion of the male and female gametes. It is the very first stage in the development of a new plant embryo.

Analyzing Other Options

• Seed coat: This protective outer layer of the seed develops from the ovary wall, not directly from the fusion of germ cells.
• Pollen tube: This structure grows from the pollen grain to deliver the male gametes to the ovule; it is a pathway, not the fusion product.
• Ovule: This structure contains the female gamete but is the container/recipient, not the result of the fusion itself. The ovule later develops into the seed after fertilization.

Therefore, the immediate result of the fusion between male and female germ cells in plants is the formation of a Zygote.
