What does Protococcus look like?
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. Colonies of these algae cells form green scum on ponds and moist rocks.
Where do green algae live?
Most green algae occur in fresh water, usually attached to submerged rocks and wood or as scum on stagnant water; there are also terrestrial and marine species. Free-floating microscopic species serve as food and oxygen sources for aquatic organisms.
What is the process of 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.
What type of protist is green algae?
Plant-like protists are called algae (singular, alga). They are a large and diverse group. Some algae, the diatoms, are single-celled….Classification of Algae.
|Type of Algae||Origin of Chloroplast||Type of Chloroplast|
|Green algae||cyanobacteria||two membranes, chlorophyll like a minority of cyanobacteria|
What is the meaning of 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 …
Where does Pleurococcus grow best?
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.
Where is algae found?
Algae are aquatic, plant-like organisms. They encompass a variety of simple structures, from single-celled phytoplankton floating in the water, to large seaweeds (macroalgae) attached to the ocean floor 2. Algae can be found residing in oceans, lakes, rivers, ponds and even in snow, anywhere on Earth.
Where is chlorophyta found?
Chlorophyta is a taxonomic group (a phylum) comprised of green algae that live in marine habitats. Some of them are found in freshwater and on land. Some species have even become adapted to thriving in extreme environments, such as deserts, arctic regions, and hypersaline habitats.
Is Protococcus asexual?
Asexual reproduction is by cell division (Protococcus), motile or nonmotile spores (Ulothrix, Oedogonium), and fragmentation.
Where are chloroplasts found in algae?
Where are chloroplasts found? Chloroplasts are present in the cells of all green tissues of plants and algae. Chloroplasts are also found in photosynthetic tissues that do not appear green, such as the brown blades of giant kelp or the red leaves of certain plants.
What type of cell is Protococcus?
The structure of a 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 Volvox multicellular or unicellular?
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.
