The spores which are produced in a sporangium are referred to as the sporangiospores. It can be composed of a single cell or can be multicellular. The sporangium generally terminates an elongate stalk, or seta, when the sporangium is ready to shed its spores. But in some species they range even from five to fifteen centimeters in their height and because of their horny appearance, the species are called 'hornworts'. It is the expanded bulbous mass of cells at the base of the sporogonium. E. 18 L).
