NEET Questions / Botany / Sexual Reproduction in Flowering Plants / Apomixis And Polyembryony
Which of the following is NOT a potential evolutionary advantage of apomixis?
Increased genetic diversity within populations
Faster colonization of new habitats
Maintenance of advantageous genotypes in unstable environments
Reduced reliance on pollinators
In a species exhibiting pseudogamy, the pollen is essential for:
Embryo development
Endosperm development
Seed coat formation
Fruit development
Identify the INCORRECT statement regarding adventive embryony:
It involves the development of embryos from the nucellus or integuments.
It is a type of sporophytic apomixis.
The embryos are genetically identical to the parent plant.
It leads to the formation of multiple embryos within a seed.
A plant species exhibits diplospory. Which of the following statements accurately describes the origin of the embryo sac in this species?
The embryo sac develops directly from the megaspore mother cell without meiosis.
The embryo sac develops from a haploid megaspore after meiosis.
The embryo sac develops from a nucellar cell.
The embryo sac develops from an integumentary cell.
Which combination of reproductive processes would result in the highest degree of genetic uniformity within a plant population?
Apomixis and self-fertilization
Apomixis and cross-fertilization
Sexual reproduction and self-fertilization
Sexual reproduction and cross-fertilization
Which of the following is a defining characteristic of apomixis?
Seed formation without fertilization
Development of fruit without pollination
Fusion of male and female gametes
Formation of diploid spores
Polyembryony refers to:
The development of multiple seeds in a fruit
The formation of more than one embryo in a seed
The fusion of multiple pollen grains with a single ovule
The development of multiple fruits from a single flower
In apomixis, the embryo develops directly from:
A haploid egg cell
A diploid cell in the ovule
The fusion of gametes
A pollen grain
