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 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.
What is algae composed of?
Algae is composed of ~ 50% carbon, 10% nitrogen, and 2% phosphorus. Table 10.3 shows the composition of various algae looking at the percentages of protein, carbohydrates, lipids, and nucleic acid.
Which part of alga is made of cellulose?
cell wall
Algae do have a cell wall that consists of cellulose, Galatians and mannans. Algae, including plants, contain cell walls that comprise either polysaccharides like cellulose or a range of glycoproteins or both.
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 …
What type of reproduction is Protococcus?
Asexual reproduction
Asexual reproduction is by cell division (Protococcus), motile or nonmotile spores (Ulothrix, Oedogonium), and fragmentation.
Where is Protococcus found?
Protococcus sp.). Vegetative cells are undergoing division. It is often referred to as moss but it is a green alga. It is commonly found as a thin, green covering the moist, shaded side of trees, rocks, and soil.
What is algae and its classification?
There is three main Algae classification: Chlorophyceae – These are called green algae, due to the presence of pigments chlorophyll a and b. Rhodophyceae – They are the red algae because of the presence of the red pigment, r-phycoerythrin. Examples are Porphyra, Gracilaria, and Gelidium.
What is algae Class 8?
Algae are simple plant- like organisms which are usually aquatic in nature. They contain a cell wall and chlorophyll and can make their own food by photosynthesis. Algae can be unicellular or multicellular. Some of the common examples are diatoms, chlamydomonas, and seaweed.
Is cellulose present in algae?
Among them, cellulose is by far the most abundant biopolymer obtained from nature and present in almost all photosynthetic organisms such as plants, algae, tunicates, as well as some bacteria.
Which is more differentiated bryophytes or algae?
The plant body of bryophytes is more differentiated than that of algae. It is thallus-like and prostrate or erect, and attached to the substratum by unicellular or multicellular rhizoids. They lack true roots, stem or leaves. They may possess root-like, leaf-like or stem-like structures.
What type of cell is Protococcus?
Algal cells
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.
What is the meaning of the word 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 trees) — compare chlorococcum.
What kind of flagella does Proteus vulgaris have?
Proteus vulgaris, a bacillus, moves by peritrichous flagella; notice flagella distributed all around the bacterial cell. Many bacteria are motile because they possess whip-like flagella.
What makes Proteus vulgaris a motile bacteria?
(1000X total magnification) Proteus vulgaris, a bacillus, moves by peritrichous flagella; notice flagella distributed all around the bacterial cell. Many bacteria are motile because they possess whip-like flagella.
