Is Pandorina a protozoa or algae?
Pandorina is a genus of green algae composed of 8, 16, or sometimes 32 cells, held together at their bases to form a sack globular colony surrounded by mucilage. The cells are ovoid or slightly narrowed at one end to appear keystone- or pear-shaped.
Is Pandorina free living?
Single/free-living – Amoeba/Chlamydomonas/Paramecium/Euglena; Colony/colonial - Eudorina/Pandorina/Volvox/sponges; Filamentous/filament – Spirogyra/Chladophora/Ulothrix/Zygnema/Oedogonium; Part of a living organism – cheek cell/onion cell/epidermal cell/parenchyma cell.
What is the meaning of Pandorina?
Definition of Pandorina
: a genus of plantlike flagellates closely related to Volvox that form a small spherical colony of sixteen cells enclosed in a delicate gelatinous envelope through which the flagella project.
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.
Are Pandorina multicellular?
4.06. 2.2 Green Algae. The volvocine algae range in complexity from unicellular Chlamydomonas through colonial genera (such as Gonium, Pandorina, and Eudorina) to multicellular organisms and are capable of both asexual and sexual reproduction.
Is Pandorina a protist?
Pandorina is a genus of green algae composed of 8, 16, or sometimes 32 cells, held together at their bases to form a sack globular colony surrounded by mucilage. ... Each cell has two flagella with two contractile vacuoles at their base, an eyespot, and a large cup-shaped chloroplast with at least one pyrenoid.
Is spirogyra a free living organism?
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.
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.
Are Volvox unicellular or multicellular?
Multicellularity in the Volvocine Algae
In a way, Volvox exhibits a relatively streamlined type of multicellularity. It possesses just two cell types, and these cells are not organized into tissues or organs.
How do Chlamydomonas reproduce?
Chlamydomonas sexually reproduces through the involvement of two gametes: Isogamy: Both of the gametes that are produced are similar in shape, size and structure. These are morphologically similar but physiologically different. Also, Isogamy is most common in sexually reproducing Chlamydomonas.
What is Pediastrum nickname?
Pediastrum. The little star in the pond.
Where is Volvox found?
Volvox can be found in ponds, puddles, and bodies of still fresh water throughout the world. As autotrophs, they contribute to the production of oxygen and serve as food for a number of aquatic organisms, especially the microscopic invertebrates called rotifers.
