Dispersal of Fruits and Seeds in Geographical area – Seed dispersal by wind, Water, Explosions, Animals

Both fruits and seeds possess attractive colour, odour, shape and taste needed for the dispersal by birds, mammals, reptiles, fish, ants and insects even earthworms. The seed consists of an embryo, stored food material and a protective covering called seed coat. As seeds contain miniature but dormant future plants, their dispersal is an important criterion […]

Ecological adaptations of Plants living in salt land – High concentration of salts

Halophytes There are special type of Halophytic plants which grow on soils with high concentration of salts. Examples: Rhizophora, Sonneratia and Avicennia. Halophytes are usually found near the seashores and Estuaries. The soils are physically wet but physiologically dry. As plants cannot use salt water directly they require filtration of salt using physiological processes. This […]

Ecological adaptations of Plants which grow perched on other plants – Epiphytes

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. Epiphytes Epiphytes are plants […]

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 […]

Ecological adaptations – Xerophytes Plants – Plant living in Dry places

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. Xerophytes The plants which are living […]

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 […]
