EXPERIMENTS IN PHOTOSYNTHESIS

MODE OF NUTRITION AND PLANT NUTRITION AUTOTROPHIC NUTRITION    Plants are referred to as autotrophs, i.e. being able to manufacture their food (Organic compound from inorganic materials such as water, carbon dioxide) Autotrophs generally have two modes of nutrition which are chemosynthesis and photosynthesis (holophytic).   HETEROTROPHIC NUTRITION This is a type of nutrition in which organisms depend directly or indirectly on autotrophs for food. All animals, fungi, protozoa and some bacteria belong to this group and they are referred to as heterotrophs   HETEROTROPHIC MODES OF FEEDING (a)        Holozoic Nutrition This is the mode of feeding in which food is ingested in the form of complex organic substances which is digested and assimilated into the body. Holozoic organisms are grouped into carnivores, herbivores, omnivores and scavengers.   (b)        Parasitic Nutrition This is the mode of feeding in which certain organisms (parasites) feed on other organisms (host). Parasites can be endoparasites… Read More »MODE OF NUTRITION AND PLANT NUTRITION
