Only some cells in multi-cellular organisms, for example the cells in important organs and in muscles, need to be supplied with oxygen and nutrients.TrueFalse

The statement is False.

In multi-cellular organisms, all cells require oxygen and nutrients to function properly, not just those in vital organs and muscles. Oxygen is critical for cellular respiration, a process that extracts energy from nutrients, supporting the metabolic needs of every cell in the body. While certain cells in specialized areas may have higher demands due to their functions (like muscle cells during exercise), the basic requirement for oxygen and nutrients is universal across all cells. Additionally, the circulatory system plays a vital role in ensuring that oxygen and nutrients are delivered throughout the entire organism, highlighting the importance of these resources for all cells, not just a select few.
