Types of Hydroponic Systems

Hydroponic systems cultivate plants in nutrient-rich water with or without using non-soil growing media around the root system. It includes deep water culture, wick system, Ebb and flow, nutrient film technique, drip system and aeroponics. For the commercial production of plants through hydroponics, a greenhouse is recommended best to cultivate plants like tomatoes, peppers, lettuces, …

Separation of Plant Pigments by Paper Chromatography

The separation of plant pigments by paper chromatography is an analysis of pigment molecules of the given plant. Chromatography refers to colour writing. This method separates molecules based on size, density and absorption capacity. Chromatography depends upon absorption and capillarity. The absorbent paper holds the substance by absorption. Capillarity pulls the substance up the absorbent …

Seed Dispersal in Plants

Seed dispersal is an essential mechanism through which spermatophytes or seed-bearing plants disperse their seeds via dispersal agents like wind, water, fruit explosion and animals. Seeds disperse into new sites where they grow or germinate under favourable conditions. Seeds first grow into seedlings and later into well-developed plants and trees, thereby providing food, shelter and …

Tropic movements in plants are the types of paratonic or induced movements. Paratonic movements include both tropic and nastic movements. In this module, we will only discuss the tropic movements in plants. Various external stimuli or environmental factors like light, gravity, water, temperature, and other factors influence tropic movement. The phenomenon of tropic movements in …
