Heterospory is the production of two or more types of spores. It is a condition of the production of more than one types (usually two) of spores in a single plant. These two types of spore differ in their formation, structure and most importantly its functions and sexuality. In Pteridophytes, these […]

Mutation Breeding Technique in Plant Breeding
Mutation breeding is a type of plant breeding technique that involves exposing plants to radiation or chemicals in order to induce mutations in their genetic material. This process can create new genetic variations that can potentially result in desirable traits such as improved yield, disease resistance, and enhanced nutritional value. […]

Ecological Adaptations of Xerophytes (with PPT)
What are xerophytes? Ø Xerophytes (xerophytic plants) are plants growing in dry habitats (xeric conditions) where the availability of water is very less. Xeric habitat are the places where water is NOT present in adequate quantity. Xerophytes are the characteristic plants of deserts or semi-deserts areas. Xerophytes can also grow in […]

Ecological Adaptations of Hydrophytes (with PPT)
What is adaptation? “Any feature of an organism which enables it to exist under conditions of its habitat is called adaptation”. Adaptations are for withstanding adverse conditions of environment and to utilize the maximum benefit of the environment (nutrition or conditions). Adaptations in plants can be of four types: 1. […]
