Question

Biological organisation starts with

• A. cellular level
• B. organismic level
• C. atomic level
• D. submicroscopic molecular level.

Answer 1

The Correct Option is D

Molecular assemblies are large organised sets of molecular units that make up parts of organelles. For example one common macromolecular assembly is the microtubule which is important in forming structure in the cell related to maintaining the cell structure or related to cell movement. The cell (plasma) membrane that surrounds many organelles and the cell is a highly organised molecular assembly.

Answer 2

Biological organization refers to the hierarchy of living organisms from small to large scale. 
It begins at the submicroscopic molecular level, when proteins, lipids, and carbohydrates are arranged to form organelles. 
The molecules, organelles, cells, tissues, organs, organ system, organism, population, community, ecosystem, and biosphere are the stages of biological organization in ascending order.
