NEET Questions / Botany / Sexual Reproduction in Flowering Plants / Post Fertilization Structure And Events
A unique feature of angiosperm embryogenesis is the formation of a suspensor. Which statement regarding the suspensor is INCORRECT?
It connects the developing embryo to the maternal tissues.
It provides a conduit for nutrients and growth regulators.
It pushes the embryo into the endosperm.
It undergoes extensive cell divisions to form the embryo proper.
Which of the following accurately describes the difference between the development of the nuclear endosperm and the cellular endosperm?
Nuclear endosperm is formed after fertilization, while cellular endosperm is formed before fertilization.
Nuclear endosperm is triploid, while cellular endosperm is diploid.
Nuclear endosperm is found in monocots, while cellular endosperm is found in dicots.
Nuclear endosperm involves free-nuclear divisions before cell wall formation, while cellular endosperm involves cell wall formation after each division.
In some plants, the integuments develop into a hard seed coat. What is the primary function of this hardened structure?
Nutrient storage for the embryo
Facilitation of seed dispersal
Promotion of germination
Protection of the embryo
The process of apomixis bypasses which critical step in sexual reproduction?
Pollination
Meiosis and fertilization
Seed dispersal
Fruit formation
The role of the endosperm is to:
Protect the embryo
Form the seed coat
Develop into the fruit
Provide nutrition to the developing embryo
Which of the following nutritive tissues in a seed is derived from the nucellus?
Endosperm
Perisperm
Coleoptile
Coleorhiza
What happens to the male gametes after they are released inside the embryo sac?
One fuses with the egg cell, and the other fuses with the polar nuclei.
Both fuse with the egg cell.
Both fuse with the polar nuclei.
They degenerate.
In angiosperms, after the pollen tube enters the synergid, what is the function of the two male gametes?
Syngamy and triple fusion
Formation of the embryo sac
Development of the pollen tube
Initiation of meiosis
