Question

Give the functions of the part of spirogyra

Answer 1

$\huge \bf \red{answer}$

Spirogyra is also known as pond silk, as its filaments shine like silk due to the presence of mucilage. The outer cell wall has pectin which dissolves continuously, thereby producing the mucilage. 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. So the name is derived from the spiral arrangement of chloroplasts in these algae. This feature is unique to this genus, which has around 400 species

Answer 2

Answer:

Spirogyra is very common in relatively clear eutrophic water, developing slimy filamentous green masses.

• Spirogyra grows submerged in water during the spring, but when there is sufficient sunlight and warmth, they produce a lot of oxygen, which sticks as bubbles between the tangled filaments.
• The filamentous masses are visible as slimy green mats as they rise to the surface.
• Spirogyra has spiral chloroplasts, a pyrenoid, a nucleus, and a cell wall.

If talked about function, both sexual and asexual reproduction is possible in spirogyra. When a plant reproduces vegetatively, it fragments; Spirogyra simply goes through intercalary cell division to lengthen the length of the new filaments.

• Scalariform conjugation requires association of two or more different filaments lined side by side, either partially or throughout their length.
• In lateral conjugation, gametes are formed in a single filament.
