What type of reproduction is Protococcus?
Protococcus reproduces only vegetatively by means of cell division. The two or more daughter cells, thus formed, may remain attached with one another for some time, or they may ultimately separate and assume a spherical shape.
Is Protococcus an algae?
The structure of the single-celled alga Protococcus is similar in some ways to a plant cell. Algal cells, like those in plants, have a nucleus and a stiff cell wall made of cellulose.
Is algae a cell?
Algae are eukaryotic organisms, which are organisms whose cells contain a nucleus and other structures (organelles) enclosed within membranes. They live in moist environments, mostly aquatic, and contain chlorophyll.
Where is Pleurococcus found?
Pleurococcus is a genus of green algae in the family Chaetophoraceae that are spherical in shape with a thick cell wall to protect themselves against excessive water loss. They can be found alone or in bunches together forming a slimy layer and grow on moist, dark patches of trees, rocks and soil.
What is the Protococcus?
: a genus of unicellular globose chiefly terrestrial green algae (family Protococcaceae) that in former classifications included most such aerial algae but is now usually restricted to forms with a single large peripheral cloroplast that divide in two planes to form thin filmy colonies (as on damp rocks or the bark of …
Why does Pleurococcus grow on the north?
Even in the North, there is enough sunlight for it to photosynthesise. The sunlight in the North is not enough to dry it out, because Pleurococcus has heavy cell walls, which prevents excessive water loss.
Is Cladophora unicellular?
The Rhodophyta, Phaeophyta and Clorophyta constitute the “algae” (singular alga) They include motile unicellular (Chlamydomonas), motile multicellular (Volvox) and static multicellular types (Cladophora, Spirogyra and “seaweeds”).
Are algae unicellular?
Algae are morphologically simple, chlorophyll-containing organisms that range from microscopic and unicellular (single-celled) to very large and multicellular.
Is green algae unicellular or multicellular?
Similar to red algae, green algae can be unicellular or multicellular. Many unicellular species form colonies.
Is scenedesmus unicellular or multicellular?
Scenedesmus is a small, nonmotile colonial green alga consisting of cells aligned in a flat plate. The colonies most often have two or four cells, but may have 8, 16, or rarely 32 and are occasionally unicellular.
Is scenedesmus a protist?
Scenedesmus is a genus of green algae, in the class Chlorophyceae. They are colonial and non-motile….
Is Protococcus a binary fission?
PROTOCOCCUS divides into two. The nucleus first divides into two equal parts, and then a furrow appears in the cytoplasm and rapidly deepens till the two halves become entirely separate. This simple method of multiplication is called binary fission.
