Write a short note on spirogyra?

spirogyra, (genus Spirogyra), any member of a genus of some 400 species of free-floating green algae (division Chlorophyta) found in freshwater environments around the world. Named for their beautiful spiral chloroplasts, spirogyras are filamentous algae that consist of thin unbranched chains of cylindrical cells.

What is spirogyra class 7th?

Spirogyra is a green, filamentous alga plant which is found in ponds, lakes and slow moving streams. Spirogyra reproduces by the asexual method of reproduction called fragmentation.

What is the function of the spirogyra?

Spirogyra is commonly found in clean water and it produces food through the process of photosynthesis. Usually, spirogyra algae are seen as floating slimy masses, during summer. They are often referred to as 'scum'.

What is spirogyra structure?

Structure of Spirogyra

Cell wall is double layered, outer layer is made up of pectin and inner layer is made up of cellulose. Exterior to the cell wall, there is layer of mucilaginous sheath which make the organism slippery. So, they are commonly called as water silk as they are slimy in nature.

What is spore formation class 10?

Spore Formation is a method in Asexual Reproduction. ... When Sporangia burst; minute single-celled, thin or thick walled structures called spores are obtained. Under suitable conditions, they develop into a new Plant. Reproducing using spores is an asexual method.

What is fragmentation 10th?

The breaking up of a body of a simple multicellular organism into two or more pieces on maturing,each of which grows to form a complete new organism is called fragmentation.

What is the common name of Spirogyra?

Spirogyra are free-floating green algae present in freshwater habitats such as ponds, lakes, etc. Spirogyra are commonly known as “water silk or pond silk”. They have a filamentous and unbranched vegetative structure.

Is Spirogyra a plant or animal?

A spirogyra is plant-like because of the presence of chlorophyll which allows it to make its own food.

What is the shape of Spirogyra?

The filamentous algae genus Spirogyra owes its name to the characteristic spiral shape of the chloroplasts possessed by its members.

What is the life cycle of Spirogyra?

The life cycle of Spirogyra occurs via one of the three ways; vegetative, asexual, and sexual. The vegetative and sexual cycles are more common than asexual cycles. A form of alternation of generation characterizes the life cycle of Spirogyra.

Is algae a plant or animal?

Algae are photosynthetic creatures. They are neither plant, animal or fungi. Many algae are single celled, however some species are multicellular. Many, but not all of red and brown algae are multicellular.

What does a Spirogyra eat?

Spirogyra gets its food through photosynthesis. Predators are mayflies, midges, stoneflies, and other aquatic insects eat that algae, either living or in detritus.

What is the habitat of Spirogyra?

Spirogyra is a large genus (about 400 species) of freshwater green algae found in shallow ponds, ditches and amongst vegetation at the edges of large lakes, generally growing free-floating. It often grows in short-lived ('ephemeral') ponds that build up during wet weather, and dry up subsquently.

What is Chara in botany?

Chara is a genus of charophyte green algae in the family Characeae. They are multicellular and superficially resemble land plants because of stem-like and leaf-like structures.
