The image is an educational graphic titled ‘Double Fertilisation.’ It contains a description of the process of double fertilisation in plants. The background is light blue with a white text box in the center. The text is in yellow and provides the following information: - After double fertilisation occurs, the triploid endosperm nucleus divides by mitosis and forms the endosperm tissue. - The endosperm tissue is the food-storing tissue which surrounds and supplies nutrients to the embryo. - The zygote divides by mitosis to form two cells, a larger cell and a smaller cell. - The larger cell develops into a suspensor that anchors the embryo to the wall of the embryo sac. - The smaller cell will become an embryo

Development of Seeds and Fruits

Only the fertilised ovule will develop into a seed.
Double fertilisation stimulates ovary wall to enlarges and develop to form fruit.

Part of Flower	Part of Fruits
Ovule	The ovule develops to become the seed in the fruit. Diploid zygote forms embryo which contains plumule,radicle and cotyledon. Triploid endosperm forms endosperm tissue to store food for growing embryo and seed germination. Intugement forms testa to protect seed.
Ovary wall	During the development of ovule and seed, the ovary develops into a fruit. Ovary wall which consists of epicarp,mesocarp and endocarp. Epicarp is the skin of fruit. Mesocarp is the flesh of fruit for most types of fruits. Endocarp surrounds seed.
Petal, stamen dan style	Degenerate and leave a scar on the ovary wall.

Development of Tomato Seeds and Fruits After Fertilisation

After fertilisation, the petals fall off, the stigma and style wither away and the carpel begins to swell.
Stigma and style degenerate while the sepals of the tomato plant can still be seen.
Ovary wall swells in the ripe fruit.
