What is the widely accepted explanation of the relationship between cells and living things?

• A. Cell theory
• B. Nucleic Acids
• C. Golgi bodies
• D. Lysosomes

Answer: (A)

The main idea being tested is how we understand the relationship between cells and living things. The widely accepted explanation is cell theory, which holds that all living things are made up of cells, the cell is the basic unit of life, and new cells come from existing cells through division. This framework explains why every organism, from a single bacterium to a giant tree, is built from cells and carries out life processes at the cellular level. It also accounts for growth, development, and reproduction, since these occur via the division and specialization of cells.

Nucleic acids are essential molecules that store and transmit genetic information, but they describe a component of biology rather than the general relationship between cells and living things. Golgi bodies and lysosomes are organelles within cells involved in processing and recycling materials; they illustrate cellular structure and function, not the overarching explanation of why living things are made of cells.
