Question

What are the three main ideas of the cell theory

Answer 1

The three main ideas of the cell theory are: all organisms are composed of cells, cells are alive and the basic living units of organization in all organisms, and all cells come from other cells.

Step-by-step explanation:

The three main ideas of the cell theory are:

1. All organisms are composed of cells. Cells are the building blocks of all living things. They are the smallest units of structure and function in organisms. For example, plants, animals, and bacteria are all composed of cells.
2. Cells are alive and the basic living units of organization in all organisms. Cells carry out all the necessary functions of life, such as metabolism, growth, and reproduction. They are responsible for maintaining homeostasis and carrying out specialized functions in multicellular organisms.
3. All cells come from other cells. New cells are produced through cell division, where existing cells divide to form two new cells. This process allows for growth, repair, and reproduction in organisms.

These three ideas form the foundation of the cell theory, which is a fundamental concept in biology.

Answer 2

The generally accepted parts of modern cell theory include:

• All known living things are made up of one or more cells.
• All living cells arise from pre-existing cells by division.
• The cell is the fundamental unit of structure and function in all living organisms.
