In plants, only the haploid stage is multicellular. The "dots" on the underside of a fern frond are spore cases; therefore, what is true of the plant to which the frond belongs? (Concept 29.4) It is a spore. It is a gamete. Somatic cells are diploid while all sex cells are haploid.
Ferns. 1. How does a fern prothallus differ from a moss protonema in appearance? - It is greatly reduced by Is the indusium haploid or diploid?

haploid sporophyte In the life cycle of a fern, the multicellular male gametangium (the sex organ that produces sperm cells) is called a(n) _____. antheridium. archegonium. frond. sporangium. 13. Fern gametophytes are _____.
Some ferns have their sporangia scattered along reduced leaf segments or along (or just in from) the margin of the leaf. In ferns, the sori form a yellowish or brownish mass on the edge or underside of a fertile frond. In some species, they are protected during development by a scale or film of tissue called the indusium, which forms an umbrella-like cover. Sori occur on the sporophyte generation, the sporangia within producing haploid meiospores. As the sporangia mature, the indusium shrivels so that spore release is unimpeded.
Antherozoid mother cell is a sporophytic body which undergoes reduction to form spores.
It will take a year or more before the new plant makes its own sori.

The fern frond (D) is emerging from an underground, horizontal stem called a rhizome (C). •The haploid gametophyte plant that produces eggs now diploid, grows into a baby fern plant a tiny new fern sporophyte with its first frond. Somatic cells are diploid while all sex cells are haploid. New diploid cells are created through the process of mitosis while new haploid cells are created through meiosis.
