In the development of the female gametophyte, the lower megaspore toward the centre of the nucellus remains functional. This functional megaspore undergoes successive mitotic divisions. This entire method of embryo sac development is called:

What is the term for genetically identical progeny produced from a single organism through asexual reproduction?
Which of the following statements about Pollination by Water (Hydrophily) are correct?
i. It is found only in some 30 genera of aquatic monocots.
ii. In Hypohydrophily, the pollen grains are lighter than water and float on the water surface to reach the stigma.
iii. In Vallisneria (Epihydrophily), the female flowers reach the water surface temporarily to ensure pollination, and the male flowers float on the surface.
iv. Pollen grains of hydrophilous flowers are long and unwettable due to the presence of mucilage, and they lack exine in some species like Zostera (sea grass).
Which of the following statements about DNA packaging in eukaryotes are correct?
i. The negatively charged DNA helix wraps around a positively charged histone octamer to form a nucleosome.
ii. The histone octamer consists of eight molecules, two of each of the four types: H2A, H2B, H3, and H4 .
iii. One nucleosome contains approximately 200 base pairs (bp) of DNA helix.
iv. The chromatin fiber is further organized into a solenoid structure of 30 nm diameter, needing additional NHC (Non-Histone Chromosomal) proteins for higher-level packaging.
