show a primitive type of sexual reproduction called genetic recombination. In this process, the exchange of genetic materials takes place by a process called conjugation . Conjugating bacterial cells are in contact through a hollow tube called pilus. In the higher organisms, sexual reproduct..

'hetero' refers to other or different and 'trophic' refers to food. Thus, the organisms that obtain their food from other organisms are called heterotrophs and the process of obtaining the food from other organisms is called heterotrophic nutrition. All heterotrophs depend dire..

'Hetero' refers to other or different and 'trophic' refers to food. Thus, those organisms which obtain their food from other organisms are called heterotrophic and the process of obtaining the food from other organisms is called heterotrophic nutrition. All the heterotrophs dep..

The photoautotrophic bacteria possess photosynthetic pigments in membrane bound lamellae (or thylakoids) and utilise solar energy. The bacterial photosynthesis is different from that of green plants since here water is not used as a hydrogen donor. Hence oxygen is not release..

Types of Heterotrophic Nutrition - Parasitic - In ancient Greece, the person getting free meals for entertaining others by his amusing converstions was called a parasite - 'para' refers to beside and 'sitos' refers to grains. Thus, parasitism is defined as an association between individua..

In 1884 a Danish physician Christian Gram devised a technique of differential staining for bacterial cells, using two simple stains. The procedure involves staining bacteria initially with a weak alkaline solution of gentian (crystalline) violet. All bacterial cells stain blue with this d..

'Auto' means self and 'trophic' refers to food. So, the organisms which synthesise their own food are called the autotrophs and the process is called autotrophic nutrition. Autotrophs include all green plants and some bacteria such as the nitrifying bacteria. The sourc..
