The chromosome (the genomic material) is a cellular component that determines the functioning of the cell. The number of chromosomal sets present in a cell defines the ploidy of that cell; sporophytic cells have two sets and are denoted as 鈥�2n鈥�, while gametic cells have a single set and are denoted as 鈥榥.鈥�

The female reproductive structure of angiosperm plants generates female gametic cells with a single set of chromosomes. These gametic cells are denoted with the term egg cell and have a ploidy level of 鈥榥.鈥�

Thus, egg cells are the female gametic cells and have an 鈥榥鈥� set of chromosomes.

Therefore, the given option is false.

The megaspore is a haploid (n) structure developed after the meiotic division of the diploid (2n) megaspore mother cell. The megaspore further divides to produce the egg cells and other structures within the female ovule.

Thus, the chromosomal content of megaspore is 鈥榥鈥� and not 鈥�2n鈥�.

Therefore, the given option is true.

Microspores are structures that develop from the meiotic division of the diploid microspore mother cell. These are produced in tetrads, have haploid chromosomal content (n), and are responsible for forming pollen grains in male angiosperms.

Thus, the pairing of chromosomal content and cell type is accurately matched in this statement.

Therefore, the given option is false.

The fertilization of the egg cells with the male pollen cells results in forming a diploid single-celled structure that divides and differentiates to form a new organism. The term zygote denotes this diploid structure.

Thus, the chromosomal content of zygote is 2n.

Therefore, the given option is false.
