Which of the following are aggregates of molecules in the cytoplasm?
A
Endospores
B
Inclusions
C
Flagella
D
Ribosomes
Verified step by step guidance1
Understand the concept of 'aggregates of molecules in the cytoplasm'. These are typically storage forms or structures within the cell that contain concentrated substances.
Identify what 'inclusions' are in microbiology. Inclusions are granules or aggregates found in the cytoplasm of bacterial cells, often serving as storage sites for nutrients or other substances.
Differentiate between the options given: Endospores, Flagella, Ribosomes, and Inclusions. Endospores are dormant, tough, and non-reproductive structures formed by some bacteria. Flagella are appendages used for movement. Ribosomes are the site of protein synthesis.
Recognize that inclusions are indeed aggregates of molecules, often containing substances like glycogen, lipids, or polyphosphate, which are stored for later use by the cell.
Conclude that among the given options, inclusions are the correct answer as they are aggregates of molecules within the cytoplasm.
