In Spirogyra, sexual reproduction occurs through conjugation in which more active male gamete passes through a conjugation tube and fuses with female gamete of the cell of the adjacent filament. Here, the male gametes are non-flagellated and show amoeboid movement.

Is Spirogyra flagellated or not?
Explanation – Spirogyra comprise isogamous gametes (similar in size), they are non-flagellated.
Is Spirogyra a diatom?
diatoms (round) amongst Spirogyra sp. green algae (long, thin) filaments. Diatoms are single-celled photosynthetic algae, of which there are about 100,000 species. ... Spirogyra is filamentous green algae named for the spiral arrangement of its chloroplasts.
Is fucus an oogamy?
"A : Fucus, a brown alga shows oogamy. R: Female gamete is quite large as compare to male gamete." A : Fucus, a brown alga shows oogamy.
What is anisogamy and examples?
Answer: The fusing gametes are different in form, size structure and behaviour as in frog and humans. Such gametes are known as anisogametes, or heterogametes, and their fusion is termed anisogamy, or heterogamy. e.g., Plasmodium, vertebrates.
What is Spirogyra filament?
Spirogyra filaments are slippery and float in large masses. Spirogyra is a genus of green algae that belong to the order Zygnematales. These free-flowing, filamentous algae are characterized by ribbon-shaped chloroplasts that are arranged in a helical manner inside the cells.
Is Sea Lettuce an animal?
L. Ulva lactuca, also known by the common name sea lettuce, is an edible green alga in the family Ulvaceae. It is the type species of the genus Ulva.
Why Spirogyra is so called?
Named for their beautiful spiral chloroplasts, spirogyras are filamentous algae that consist of thin unbranched chains of cylindrical cells. They can form masses that float near the surface of streams and ponds, buoyed by oxygen bubbles released during photosynthesis.
Do protists have ribosomes?
The organelles in protists include things like ribosomes, which are the organelles responsible for synthesizing all the proteins the protist will need; mitochondria, which are the organelles responsible for turning food into energy the cell can use; and chloroplasts, which are the organelles that are able to capture ...
Is Plasmodium heterotrophic or autotrophic?
Complete answer: Plasmodium is unicellular eukaryotes that are obligate parasites of insects and vertebrates. These organisms are parasites and feed on the blood of the host cell. Thus, they show heterotrophic nutrition.
What are some examples of phytoplankton?
Some phytoplankton are bacteria, some are protists, and most are single-celled plants. Among the common kinds are cyanobacteria, silica-encased diatoms, dinoflagellates, green algae, and chalk-coated coccolithophores.
Is Spirogyra a phytoplankton?
Spirogyra is a common green alga found in freshwater in quiet areas of streams, rivers, ponds, and marshes. This phytoplankton grows in long thin un-branched strands (filaments, strings) the thickness of a human hair. There are over 400 species of Spirogyra.
Is Spirogyra photosynthetic?
Green algae like Spirogyra are also an important part of the aquatic ecosystems as they are photosynthetic and thus provide oxygen to other organisms in the water.
