Ecological adaptations – plants Living in Too wet or too Dry conditions – Mesophytes

Ecological adaptations The modifications in the structure of organisms to survive successfully in an environment are called adaptations of organisms. Adaptations help the organisms to exist under the prevailing ecological habitat. Based on the habitats and the corresponding adaptations of plants, they are classified as hydrophytes, xerophytes, mesophytes, epiphytes and halophytes. Mesophytes The plants which […]

Interspecific interactions/ Co-evolutionary dynamics

i. Mimicry: It is a phenomenon in which living organism modifies its form, appearance, structure or behavior and looks like another living organism as a self defence and increases the chance of its survival. Floral mimicry is for usually inviting pollinators but animal mimicry is often protective. Mimicry is a result of evolutionary significance due […]

Biotic factors – Plant and Animal Interactions

The interactions among living organisms such as plants and animals are called biotic factors, which may cause marked effects upon vegetation. The effects may be direct and indirect and modifies the environment. The plants mostly which lives together in a community and influence one another. Similarly, animals in association with plants also affect the plant […]

Topographic factors involved in plant life – Surface of the Earth

Topographic factors The surface features of earth are called topography. Topographic influence on the climate of any area is determined by the interaction of solar radiation, temperature, humidity, rainfall, latitude and altitude. It affects the vegetation through climatic variations in small areas (micro climate ) and even changes the soil conditions. Topographic factors include latitude, […]

Climatic Factors involved in the plant life – Light, temperature, water, wind, fire

Climatic Factors Climate is one of the important natural factors controlling the plant life. The climatic factors includes light, temperature, water, wind and fire. A – Light Light is a well known factor needed for the basic physiological processes of plants, such as photosynthesis, transpiration, seed germination and flowering. The portion of the sunlight which […]

Ecology, Definition of Ecology,

The term “ecology” (oekologie) is derived from two Greek words – oikos (meaning house or dwelling place and logos meaning study) It was first proposed by Reiter (1868). However, the most widely accepted definition of ecology was given by Ernest Haeckel (1869). Alexander von Humbolt – Father of Ecology Eugene P. Odum – Father of […]

Intellectual Property Right (IPR) – Copyrights, Patents and Trademarks

Intellectual property right (IPR) is a category of rights that includes intangible creation of the human intellect, and primarily consists of copyrights, patents, and trademarks. It also includes other types of rights, such as trade secrets, publicity rights, moral rights, and rights against unfair competition. In biotechnology, the transformed microorganisms and plants and technologies for […]

Conservation of plant genetic resources

Germplasm Conservation Germplasm conservation refers to the conservation of living genetic resources like pollen, seeds or tissue of plant material maintained for the purpose of selective plant breeding, preservation in live condition and used for many research works. Germplasm conservation resources is a part of collection of seeds and pollen that are stored in seed […]

Somatic Embryogenesis

Somatic embryogenesis is the formation of embryos from the callus tissue directly and these embryos are called Embryoids or from the in vitro cells directly form pre-embryonic cells which differentiate into embryoids. Applications of Somatic Embryogenesis •Somatic embryogenesis provides potential plantlets which after hardening period can establish into plants. •Somatic embryoids can be be used […]

Technique Involved in Plant Tissue Culture – PTC

1. Sterilization: Sterilization is the technique employed to get rid of microbes such as bacteria and fungi in the culture medium, vessels and explants. i. Maintenance of Aseptic Environment: During in vitro tissue culture maintenance of aseptic environmental condition should be followed, i.e., sterilization of glassware, forceps, scalpels, and all accessories in wet steam sterilization […]

Plant Tissue Culture

Plant Tissue Culture (PTC) Plant tissue culture is used to describe the in vitro and aseptic growth of any plant part on a tissue culture medium. This technology is based on three fundamental principles: •The plant part or explant must be selected and isolated from the rest of plant body. •The explant must be maintained […]

What is the Basic Concept of Tissue Culture

Basic concepts of Tissue Culture Basic concepts of plant tissue culture are totipotency, differentiation, dedifferentiation and redifferentiation. Totipotency The property of live plant cells that they have the genetic potential when cultured in nutrient medium to give rise to a complete individual plant. Differentiation The process of biochemical and structural changes by which cells become […]
