검증된 단계별 안내1
Understand the life cycle of a fern, which includes both a sporophyte and a gametophyte stage. The gametophyte stage is where the sex organs develop.
Identify the male gametangium in ferns, which is responsible for producing sperm cells. This structure is known as the antheridium.
Differentiate between the male and female gametangia. The female gametangium is called the archegonium, which produces eggs.
Recognize other parts of the fern: the frond is the leaf-like part, rhizoids are root-like structures, and sporangium is where spores are produced.
Confirm that the multicellular male gametangium in ferns is indeed called an antheridium, as it is the structure that produces sperm cells.
