Final answer:
The statements provided pertain to the cell theory, which articulates that all organisms consist of cells, cells are the basic unit of life, and all cells are derived from pre-existing cells. One statement, however, is incorrect; prokaryotic cells do not contain a nucleus or organelles.
Step-by-step explanation:
Understanding Cell Theory
The core concepts that you've listed are foundational to the cell theory, which is a critical and fundamental principle in biology. The cell theory comprises several key points:
- All organisms are made of one or more cells.
- The life functions, including metabolism, growth, and reproduction, occur within cells.
- All cells come from already existing cells, demonstrating a continuous line of cell division and life.
Therefore, the statements you have been studying all relate to this central theory. They correctly identify that a) all cells come from pre-existing cells—that is, cells do not spontaneously appear but rather are the result of cell division, b) all living organisms are composed of cells—whether it be a single cell (like bacteria) or trillions (like in humans), and c) a cell is the basic unit of life—which means every cell has the capacity to carry out the essentials of life processes.
However, item d) is incorrect as it states nucleus and organelles are found in prokaryotic cells. Prokaryotic cells do not have a nucleus or membrane-bound organelles, unlike eukaryotic cells.
