Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Produced when the pollen fertilizes the egg.
A
seed
B
Roots
C
fruit
D
petals
Explanation: 

Detailed explanation-1: -After fertilization, the fertilized ovule forms the seed while the tissues of the ovary become the fruit.

Detailed explanation-2: -Fertilisation takes place inside the ovary when the nucleus of pollen grain fuses with the nucleus of an ovule to produce a zygote.

Detailed explanation-3: -This pollen tube carries a male gamete to meet a female gamete in an ovule. In a process called fertilisation, the two gametes join and their chromosomes combine, so that the fertilised cell contains a normal complement of chromosomes, with some from each parent flower.

Detailed explanation-4: -From the anther the pollen grains are first deposited on the pistil’s surface, the stigma. There they germinate and form pollen tubes, which grow downward through the style toward the ovules. Fertilization occurs as a sperm cell in a pollen tube fuses with the egg cell of an ovule, resulting in a plant embryo.

Detailed explanation-5: -When sperm fertilizes (meets) an egg, this fertilized egg is called a zygote (ZYE-goat). The zygote goes through a process of becoming an embryo and developing into a fetus.
