. Most of them are saprotrophic. Some are found as parasites on algae and other plants. Slime moulds generally reproduce asexually by fragmentation or by forming sporangia, which produces spores having a cellulose cell wall. Sexual reproduction involves isogamy or anisogamy. fig..

The hardness and elasticity of steel can be controlled by heat treatment. When it is heated to redness and then allowed to cool slowly, it becomes soft. This process is known as annealing . If it is cooled suddenly by plunging into ice-cold water (quenching) , steel becomes ..
Rhodophyta
It is a group consisting of multicellular aquatic algae which exhibit a highly varied organisation of the plant body. They are generally found attached to rocky stones. Some of them occur as total or semi parasites on the other algal plants. The members of this group are commonly called ..

Cyanobacteria - The group cyanobacteria includes another successful group of prokaryotes namely blue green algae. They are photoautotrophic prokaryotes occupying a wide range of habitats. They are predominantly aquatic, found mostly in fresh water bodies. Some species occur in marine wate..
Merits and Demerits of Two Kingdom Classification
The two-kingdom classification received considerable recognition from biologists and was in use for quite a long period of time. However, as more and more information started emerging on the various groups of plants and animals, this system of classification was found to be inadequate. Studies made..
Effect of Light on Seed Germination
). On absorption of light it gets converted into a metabolically active P f r . P f r promotes germination. P f r converts back to P r after absorbing far red light (730nm). Treatment with red light (R) stimulates seed germination, whereas far red light (FR) ..
i) Halogenation
Carboxylic acids having an a -hydrogen are halogenated at the a -position on treatment with chlorine or bromine in the presence of small amount of red phosphorus to give a -halocarboxylic acids. This reaction is known as Hell - Volhard Zelinsky reaction...
