NEET BIOLOGY

Detailed explanation-1: -Archaebacteria are both Autotrophs and Heterotrophs. This means that some can create their own food within themselves and others depend on other things to obtain their food. This is the cell structure of the archaebacteria which includes the cell wall that does not contain peptidoglycan.

Detailed explanation-2: -in the cell. Body structure : Archaea are single-celled organisms, but they are sometimes found in colonies. Food: Archaea are autotrophic(make their own food). They use chemical synthesis to make food.

Detailed explanation-3: -Most autotrophs make their “food” through photosynthesis using the energy of the sun. Heterotrophs cannot make their own food, so they must eat or absorb it. Chemosynthesis is used to produce food using the chemical energy stored in inorganic molecule s.

Detailed explanation-4: -Most archaea are chemotrophs and derive their energy and nutrients from breaking down molecules in their environment. A few species of archaea are photosynthetic and capture the energy of sunlight.

Detailed explanation-5: -All pathogenic bacteria are heterotrophic All bacteria obtain energy by oxidizing preformed organic molecules (carbohydrates, lipids and proteins) from their environment.
