The picture on the right shows the structure of peach blossom. Please answer the following questions according to the pictures. (1) When the bees came back from collecting honey from this flower, they found that they were a little yellow. (1) Peach blossom is an insect-borne flower, which attracts insects to collect pollen with its bright corolla and fragrant smell. Pollen is produced by anthers with flowers, which is 1 in the above structure.

(2) Double fertilization refers to the phenomenon that the anthers of angiosperms fall on the stigma of flowers, which stimulates the stigma to germinate and produce pollen tubes. The pollen tube is constantly elongated and reaches the interior of the ovary. There are two sperm in the pollen tube, one of which fuses with the egg cell to form a fertilized egg, and the other fuses with the polar nucleus of the central cell (usually two) to form the polar nucleus of the fertilized egg. Double fertilization is a unique fertilization method for green flowering plants.

(2) After double fertilization, the ovary finally develops; Ovary wall develops into fruit skin; Ovules in ovary develop into seeds; The integument develops into seed coat; The fertilized egg develops into embryo, and the fertilized polar nucleus develops into endosperm.

So the answer is: (1) pollen; 1 anther; It has bright petals, fragrant smell and sweet nectar.

(2)4 pollen tubes; Ovary; Second; Egg cell; Polar nucleus; Green flowering plants; double fertilization
