Ferns and horsetails have two free-living generations: a diploid sporophyte generation (spore-producing plant) and; a haploid gametophyte generation (gamete-producing plant). Plants we …

2023年5月28日 · The fern life cycle is different from the life cycle of flowering plants. Ferns use alternation of generations, with a sporophyte diploid (2n) generation and a gametophyte (n) …

The gametophyte of ferns is a free-living organism, whereas the gametophyte of the gymnosperms and angiosperms is dependent on the sporophyte. The life cycle of a typical …

The life cycle of ferns is different from other land plants as both the gametophyte and the sporophyte phases are free living. This interactive illustrates the alternation of generations in …

In ferns, the multicellular sporophyte is what is commonly recognized as a fern plant. On the underside of the fronds are sporangia. Within the sporangia are spore producing cells called …

2020年12月28日 · The leafy fern with spores is part of the diploid generation, called the sporophyte. A fern's spores don't grow into leafy sporophyte. They aren't like seeds of …

The asexual form, or sporophyte form, is represented by the fern plant as it is commonly known and is diploid (2N). Sporophytes can reproduce either by vegetative cloning via their rhizomes …

2020年12月31日 · In temperate regions, the stems of ferns called rhizome grow underground. The leaves called fronds grow up from the rhizome each spring. The plant we recognize as a …

2025年1月8日 · The young sporophytes of ferns remain attached to the gametophytes for varying lengths of time, absorbing nutrients from the gametophyte through the foot. Once the …

Ferns. Most ferns have a small, photosynthetic gametophyte that usually is less than 1 cm across and one cell thick, i.e., a sheet. It lacks a stem axis and is often ‘heart-shaped’ (Fig. 6-8 and …
