Question

1. what are organelles? what are their functions? 3. explain how the structures of cells and viruses are similar. how are they different?

Explanation:

Cells and viruses have some similarities and differences in structure. Similarities: Some viruses have an outer envelope similar to the cell - membrane in terms of being a lipid - containing layer. Differences: Cells are the basic unit of life, with a complete set of organelles (such as nucleus, mitochondria, etc.) for metabolism, growth, and reproduction. Viruses are non - cellular entities, much smaller than cells, consisting mainly of nucleic acid (DNA or RNA) surrounded by a protein coat, and they cannot carry out metabolic processes on their own and rely on host cells for replication.

Answer:

Similarities: Some viruses have an envelope similar to cell - membrane in composition. Differences: Cells are living units with organelles; viruses are non - cellular, mainly composed of nucleic acid and protein coat and rely on host cells for replication.
