Batrachospermum Occurrence:- (1) Batrachospermum is fresh water alga. (2) It is found in clear, cool, and running streams. (3) Deepwater plants are dark violet or reddish in color. But the shallow-water species are olive green. (4) The intensity of light changes the color of pigments. (5) The thallus is attached to the substratum. Vegetative structure (1) The thallus of an adult plant is soft, thick, filamentous. (2) It is freely branched and gelatinous. (3) The central axis is made up of a single row of large cells. Whorls of branches of limited growth are developed on this axis. (4) These branches are filamentous and dichotomously arranged. (5) The main axis is corticated. It consists of a row of elongated cylindrical cells. (6) It is differentiated into nodes and internodes. (7) There are two types of branches that arise from the nodes: Branches of limited growth Branches of unlimited growth Batra
Kingdom Monera Characteristics:- Eubacteria A) Bacteria are the soil members found everywhere, Hundreds of the bacteria found in a handful of the soil. B) They are also live in extreme conditions like hot springs, deserts, snow, and deep oceans. Where very few other life forms can survive. C) Mainly bacteria are Autotrophic, chemoautotrophic, and heterotrophic. D) According. To their shape, these are of 4-types. Coccus:- Spherical shaped bacteria e.g.Stephlococcus. Bacillus:- Rod-shaped bacteria,e.g.:- Bacillus thygrogenesis. Vibrio:- comma-shaped bacteria e.g. Vibrio cholera. Spiral:- Spiral shaped bacteria e.g. Spirilla. Note:- 6 th kingdom classification was given by Robert Woose . He classifies Kingdom monera into two groups Archebacteria and Eubacteria Archebacteria:- Live in halophiles,thermoacidophilous and as a methanogens due to the different composition of cell wall. e.g. Thermoacidophilous-Taq polymerase.which activate at 96c ,Meth
