Which of the following is a correct statement ?a)Bacteria are exclusiv...
Bacteria are exclusively heterotrophic organisms.
This statement is incorrect. Bacteria can be classified into various types based on their mode of nutrition. While some bacteria are indeed heterotrophic, meaning they obtain their nutrients by consuming organic matter, there are also bacteria that are autotrophic. Autotrophic bacteria are capable of synthesizing their own food using inorganic substances such as sunlight or chemicals.
Slime moulds are saprophytic organisms classified under Kingdom Monera.
This statement is incorrect. Slime moulds are not classified under Kingdom Monera. They belong to the Kingdom Protista. Slime moulds are eukaryotic organisms that exhibit characteristics of both fungi and protozoa. They are typically found in moist environments and feed on decaying organic matter as saprophytes.
Mycoplasma have DNA, Ribosome, and cell wall.
This statement is incorrect. Mycoplasma is a genus of bacteria that are unique in their lack of a cell wall. Unlike most bacteria, which have a cell wall made of peptidoglycan, Mycoplasma species have a plasma membrane surrounded by a lipid bilayer. This feature allows them to be more flexible in shape and size. However, Mycoplasma do possess DNA and ribosomes, which are essential for their cellular functions.
Cyanobacteria are a group of autotrophic organisms classified under Kingdom Monera.
This statement is correct. Cyanobacteria, also known as blue-green algae, are a group of photosynthetic bacteria that are classified under Kingdom Monera. They are capable of carrying out photosynthesis and produce oxygen as a byproduct, similar to plants. Cyanobacteria are found in various aquatic and terrestrial habitats and play a crucial role in the cycling of nutrients and the production of oxygen in the environment.

Which of the following is a correct statement ?a)Bacteria are exclusiv...
The correct statement is (d) Cyanobacteria are a group of autotrophic organisms classified under Kingdom Monera.
Let's go through each statement and evaluate its accuracy:
(a) Bacteria are exclusively heterotrophic organisms: This statement is incorrect. Bacteria are a diverse group of microorganisms that can be both heterotrophic (obtaining energy from organic compounds) and autotrophic (able to produce their own energy through photosynthesis or chemosynthesis). Some bacteria are capable of photosynthesis and are classified as autotrophs, while others rely on consuming organic matter and are classified as heterotrophs.
(b) Slime moulds are saprophytic organisms classified under Kingdom Monera: This statement is incorrect. Slime moulds are not classified under Kingdom Monera. They belong to a separate group called the Kingdom Protista. Slime moulds are eukaryotic organisms that are known for their unique life cycle, which involves both amoeboid and fungus-like stages. They are not classified as saprophytic, as they obtain nutrients through phagocytosis (engulfing food particles) rather than decomposing dead organic matter.
(c) Mycoplasma have DNA, Ribosome, and cell wall: This statement is incorrect. Mycoplasma is a genus of bacteria that is characterized by its unique feature of lacking a cell wall. Unlike most bacteria, Mycoplasma species do not possess a peptidoglycan cell wall. However, they do have DNA and ribosomes, which are essential components of all living cells.
(d) Cyanobacteria are a group of autotrophic organisms classified under Kingdom Monera: This statement is correct. Cyanobacteria are a group of photosynthetic bacteria that are capable of producing their own food using sunlight. They are classified under the Kingdom Monera, which represents prokaryotic organisms. Cyanobacteria are important primary producers in aquatic environments and are responsible for oxygen production through photosynthesis.
