Position of Polar Nuclei in Relation to Egg ApparatusThe polar nuclei in plants are located in close proximity to the egg apparatus. However, their exact position in relation to the egg apparatus can vary depending on the plant species. Below or Above Egg ApparatusIn some plant species, the polar nuclei are located below the egg apparatus.

During double fertilization, one sperm cell fuses with the egg cell to form the zygote, while the other sperm cell fuses with the polar nuclei to form the endosperm, which provides nutrients for the developing embryo.AntipodalsThe antipodals are three cells found at the opposite end of the female gametophyte from the egg cell.

Question: Double fertilization occurs when O the sperm and tube nuclei fertilize the egg. two sperm cells fertilize the two polar nuclei one sperm fuses with the egg and the other sperm fuses with both polar nuclei O the polar nuclei fuse with the egg after it has fused with the sperm. None of these. Previous

41. Double fertilization means that A) flowers must be pollinated twice to yield fruits and seeds. B) one sperm is needed to fertilize the egg, and a second sperm is needed to fertilize the polar nuclei. C) the egg of the embryo sac is diploid. D) every sperm has two nuclei. 42. Unripe fruits protect seeds from predation and carly germination.

Question: 74. Double fertilization means that a. every sperm has two nuclei b. the egg of the embryo sac is diploid C. one sperm fertilizes the egg and the second sperm fertilizes the polar nuclei d. flowers must be fertilized twice to yield fruits and seeds 75. Which of these represents the female gametophyte generation of an angiosperm? a.

Identify the components involved in double fertilization: one sperm fusing with the egg cell and the other sperm fusing with the polar nuclei. In the above given questions 1st and 2nd questions are same. =}Answer is the EGG CELL.

One pollen grain combines with the egg to form the zygote, and one pollen grain combines with the polar nuclei to form endosperm. Two sperm combine with a polar nucleus to form endosperm O One sperm combines with the polar auclei to form the zygote, and one sper combines with the egg to form endosperm O One sperm combines with the egg to form ...

Question: What happens to the sperm nuclei that do not fertilize the egg to form a zygote? A.they fuse with the polar nuclei of the egg and form the endosperm nucleus B.they move to another egg and form a zygote with the second egg C.they form the wings that allow the fruit to disseminate D.they die and do not fuse with any nuclei

Multiple Choice One sperm fertilizes the egg and the other sperm unites with the two polar nuclei to form the endosperm. Two sperm fertilize the egg. The sperm must burrow into two different layers of the female gametophyte before it reaches the egg and forms the zygote. Each sperm unites with a different polar nuclei to help form the endosperm.
