Main Features of Angiosperms

Angiosperms or flowering plants are the most advanced, most diverse and most dominant group of land plants. They are seed-producing plants and can be distinguished from the gymnosperms by a series of derived characteristics such as flowers, endosperm within the ..

Gymnosperms

Gymnosperms are called so because they have naked ovules / seeds. In terms of plant evolution, they are first seed-bearing plants. They are inferior to Angiosperms because in Angiosperms, the ovules are covered. Common gymnosperms include Conifers, Cycads, Ginkgo, and ..

Pteridophytes

Pteridophytes are commonly known as Ferns. There are around 12,000 species of Ferns, many of them are generally used a decoration / ornamental plants. Position of Pteridophytes in Evolution In the evolutionary stages, Ferns are next advanced level after Bryophytes. ..

Bryophytes

The common word for Bryophytes is Moss, which are the first land plants in context with evolution of plants. The branch of science that deals with Bryophytes is called Bryology. Please note that Mosses don’t have a vascular tissue such ..

Algae

Algae (seaweeds) are usually aquatic, either marine or fresh water plants. A few algae also occur in terrestrial habitats such as moist soils, wet rocks, tree trunks, etc. These are unicellular or multicellular, autotrophic plants which don’t have vascular tissues ..

Fungi and Lichens

Fungi are among the most primitive members of the plant kingdom. Study of the fungi is called mycology. The fungi are non-chlorophylous, nucleated, non-vascular, thallophytic micro organism and due to lack of chlorophyll they do not prepare their own food. ..

Bacterial Diseases

Common Bacterial diseases include Diarrhoea, Dysentery, Typhoid, Whooping Cough, TB, Diphtheria, Cholera etc. Diarrhoea Diarrhea can be caused by all sorts of parasites including viruses, Bacteria and protozoa.  Most common virus causing Diarrhoea in adults is Norovirus.  Most common virus ..

Bacteria: Use in Industry, Food Processing, Soil Health and Bioremediation

Some other notable used of bacteria include in Dairy Industry, Food Industry, Soil Health, Bioremediation, Biotoilet Dairy Industry In Dairy Industry, Lactobacillus bacteria are used in fermentation of lactose sugar to form lactic acid (in curd). Lactobacillus in combination with yeasts ..
