Of the following list, flagellated (swimming) sperm are generally present in which groups? 1. Lycophyta 2. Bryophyta 3. Angiosperms 4. Chlorophyta 5. Pterophyta

Ferns have a well-developed vascular system. They also have true stems, roots, and complex leaves. Ferns produce multi-flagellated sperm (antherozoids) from the antheridium.

The sperm of seed plants have no flagella. They lack antheridia, and only a few still have an archegonia. Unlike the more primitive ferns and fern allies, seed plants are mostly dioecious , …

No, ferns do not have flagellated sperm. Ferns are non-flowering plants and they reproduce using spores, which are produced by their sporophyte stage of the plant’s life cycle. Unlike other …

The male structure, the antheridium, contains many flagellated sperm. The sperm are released from the antheridium and swim through a thin film of water to a nearby archegonium to fertilize …

Jan 8, 2025 · The sex organs of ferns are of two types. The sperm-producing organ, the antheridium, consists of a jacket of sterile cells with sperm-producing cells inside. Antheridia …

Morphology of flagellated sperm—In ferns, sperm are coiled with an elongate nucleus extending for much of the cell length (Figs. 12–14). Cytoplasm is reduced to a thin layer around the nucleus.

Obligate apogamy often occurs naturally in species of ferns that produce no or only one type of gametangia. Because water is required for the flagellated sperm to swim to the egg in ferns, …

Each antheridium produces many flagellated sperm cells which swim toward the archegonia. The sperm cells of some ferns have up to Uluhe ferns ( Dicranopteris emarginata ) in Hawaii. JLM …

Ginkgos and cycads show a transitional stage between the primitive ferns and the more advanced conifers and flowering plants. They have flagellated sperm, but the male gametophyte grows a …
