Detailed explanation-1: -Each pollen grain is a minute body, of varying shape and structure, formed in the male structures of seed-bearing plants and transported by various means (wind, water, insects, etc.) to the female structures, where fertilization occurs. In angiosperms, pollen is produced by the anthers of the stamens in flowers.
Detailed explanation-2: -The male reproductive system contains the external genitals (the penis, testes and the scrotum) and internal parts, including the prostate gland, vas deferens and urethra.
Detailed explanation-3: -Stamens: Male Reproductive Organs A stamen consists of an anther (which produces pollen, the male reproductive cell) and a filament.
Detailed explanation-4: -Pollen grains consist of three parts: The inside of the cell, which is filled with living cytoplasm, deteriorates rapidly during fossilisation. Intine, the inner layer of the cell wall comprises the cellulose and pectin. Similar to the cytoplasm, the intine also degrades rapidly during fossilisation.
