What is Pandorina and Eudorina?

Abstract. Traditionally, the volvocacean genera Pandorina and Eudorina are distinguished by vegetative morphology: Eudorina has hollow coenobia with loosely arranged spherical to ovoid cells, whereas Pandorina coenobia are compact with pear- to keystoneshaped cells contiguous in the centre.

Is Volvox a Chlamydomonas?

The unicellular species in this group is named Chlamydomonas reinhardtii (hereafter Chlamydomonas), and its best-studied, close multicellular relative is a species named Volvox carteri (hereafter Volvox).

Is Pandorina a cyanobacteria?

There are many different classes of microorganisms i.e. cyanobacteria and algae (Nostoc sp., Anabaena sp., Pandorina sp.

What is the classification of Pandorina?

Chlorophycean green algae
Pandorina/Class

Is Pandorina autotrophic?

They are autotrophs due to the presence of chloroplast. The identified specimen is Pandorina. It undergoes asexual reproduction by forming auto-colonies and it also undergoes isogamous sexual reproduction.

Is Eudorina Oogamy or Isogamy?

Volvox and other large colonials (Pleodorina, Eudorina) transitioned from an isogamous ancestral mating system to an anisogamous or oogamous one with eggs and sperm.

Is Volvox unicellular or colonial?

Volvox and its relatives live in freshwater ponds all over the world. Some of the species are unicellular, while others live in colonies of up to 50,000 cells. Many of the colonial algae species are visible to the eye and appear to be little green spheres rolling through the water.

What is the relationship between Chlamydomonas and Volvox?

Chlamydomonas is unicellular and reflects the ancestral state of the group, while Volvox is multicellular and has evolved numerous innovations including germ-soma differentiation, sexual dimorphism, and complex morphogenetic patterning.

Is Pandorina a colonial?

Asexual reproduction is by simultaneous division of all cells of the colony to form autocolonies that are liberated by a gelatinization of the colonial envelope….

What is the habitat of Pandorina?

SAG 60-1b Pandorina morum

Is Pandorina motile?

Pandorina (division Chlorophyta) A genus of green algae in which the cells fit closely together to form motile, spherical colonies (coenobia) of 4–32 cells. They are common in puddles, ponds, lakes, rivers, etc.

Is Pandorina a colony?

Pandorina is a green alga composed of 8, 16, or sometimes 32 cells held together at their bases to form a globular colony surrounded by mucilage.
