Question

What statements summarize scientists' concept of cells

Answer 1

The concept of cells is encapsulated by the cell theory, which states that all organisms are made up of cells, cells are the simplest units of life, and all cells are derived from other cells. Essential structures common to all cells include cytoplasm, a plasma membrane, chromosomes, and ribosomes.

Step-by-step explanation:

Cell Theory Overview :-

Scientists' concept of cells is summarized by the cell theory, which is a fundamental concept in biology. The cell theory entails several key points:

1. All organisms are composed of cells, which are the basic units of life.
2. Cells are alive and represent the simplest forms of life that can perform all essential life processes.
3. All cells come from other cells, which is a principle stating that cells are self-replicating and are derived only from existing cells.

The cell theory was formulated based on contributions from scientists such as Theodor Schwann, Matthias Jakob Schleiden, and Rudolph Virchow. The development of microscopes, including modern electron microscopes, has greatly enhanced our understanding of cellular structure and function, revealing that all cells have cytoplasm, a plasma membrane, chromosomes containing DNA, and ribosomes for protein synthesis. Despite variations in size, shape, and specific functions, these structures are common to all cells.

Answer 2

This is really basic, containing much on the history of cell biology. The cell theory, or cell doctrine, states that all organisms are composed of similar units of organization, called cells. The concept was formally articulated in 1839 by Schleiden & Schwann and has remained as the foundation of modern biology.
