• A. Same pollen tube of a pollen grain
• B. Different pollen tube of a pollen grain
• C. Different pollen tubes of a different pollen grain
• D. Both 1 and 3

Answer 1

The correct option is A Same pollen tube of a pollen grain

Angiosperms undergo 2 fertilization where a zygote and endospherm are both formed

It involves two sperms cells, one fertilizes the egg cell to form the zygote, while the other fuses with the two polar nuclei that form the endosperm. After fertilization, the fertilized ovule forms the speed while the tissues of the ovary becomes the fruit.

In the first stage of embryonic development, the developing embryo has a heart shape due to the presence of cotyledons. As the embryo grows, It begins to bend as it fills the seed; at this point, the seed is ready for disposal. After pollen gets deposited on the stigma, It must germinate and grow through the style to reach the ovule. The microspores, or the pollen, contain two cells; The pollen tube cell and the generative cell.

$\therefore A$ is the correct answer.
