: having oogonia borne on normal-sized plants and antheridia borne on greatly reduced plants or filaments —used of green algae of the family Oedogoniaceae — compare macrandrous.
Is Oedogonium multicellular?
ADVERTISEMENTS: The thalloid plant body is green, multicellular and filamentous. The filaments are unbranched and cells of each filament are attached end to end and form uniseriate row (Fig.
Are Oedogonium motile? Oedogonium filaments are typically unbranched and only one cell thick. … Asexual reproduction is by motile and nonmotile spores, formed only in cells with an apical cap. The motile reproductive bodies are characterized by a ring of cilia at the anterior end.
How do you pronounce Ulva?

Is Pinus a bryophyte? In bryophytes (Funaria and Marchantia) fertilisation is dependent on water for the transfer of sperm to the egg. … Pinaceae (Pinus) has well developed gametophyte in which sperm cells are fertilised with egg cell within the ovule. Hence, pinus is the correct option.
Is Fern a bryophyte?
No, ferns are not bryophytes. They are pteridophytes. They are non-flowering, vascular plants. Unlike bryophytes, they possess true roots, stem and leaves.
Why is Funaria a bryophyte? Funaria hygrometrica is the most common species. Funaria hygrometrica is called “cord moss” because of the twisted seta which is very hygroscopic and untwists when moist. The name is derived from the Latin word “funis”, meaning “a rope”.

What is filament in algae? The algae grow in long chains and form visible strings, or filaments, of algae. The filaments of algae can intertwine and form thick mats that resemble wet wool. Mats of filamentous algae commonly float to the surface of lakes and ponds which can be visually unappealing.
Is spirogyra photosynthetic or heterotrophic?
Some protists are autotrophic, others are heterotrophic. Recall that autotrophs make their own food through photosynthesis or chemosynthesis (see the Photosynthesis concepts). Photoautotrophs include protists that have chloroplasts, such as Spirogyra. Heterotrophs get their energy by consuming other organisms.
Is Mucor Septate or Nonseptate? Fungi of the genus Mucor and the division Zygomycetes are non-septate. Non-septate hyphae do have some septa, but they are found only at the branching points. If there were no septa at all, the entire fungus would be at risk of compromise if even one hypha were damaged.
Why can we see Mucor on bread with naked eye?
The microorganisms cannot be seen with naked eyes because they are very small in size. Some of these, such as fungus growing on bread, can be seen with a magnifying glass. Others cannot be seen without the help of a microscope. That is why these are called microorganisms or microbes.
