NEET BIOLOGY

Detailed explanation-1: -Sori are formed on sporophyte generation, sporangia present in the sori produce haploid meiospores.

Detailed explanation-2: -Sori (singular: sorus) are groups of sporangia (singular: sporangium), which contain spores. Sori are usually found on the underside of the blade. Young sori are commonly covered by flaps of protective tissue called indusia (singular: indusium).

Detailed explanation-3: -Each of the sori contains diploid cells called spore mother cells. Spore mother cells undergo meiosis to produce haploid spores, which are stored in a structure called a sporangium. Remember, a haploid cell, which is often represented as n, contains only one set of chromosomes, half the number of most other body cells.

Detailed explanation-4: -Sori form on the fronds. Each contains many sporangia mounted on stalks. Within each sporangium, the spore mother cells undergo meiosis producing four haploid spores each.

Detailed explanation-5: -The fern sori
