Living cells.
This principle is called the Cell Theory, which states that new cells can only arise from pre-existing cells. It was proposed by scientists Schleiden and Schwann in the 19th century, laying the foundation for modern biology.
The cells that make up the epidermis are both living and dead. The top layer of the epidermis, known as the stratum corneum, is made up of dead cells called corneocytes. However, the lower layers of the epidermis contain living cells that are actively dividing and producing new skin cells.
1. all organisms are made up of one or more cells. 2. cells are the basic units of structure and function in living things. 3. new cells are produced by the division of other living cells.
Viruses are the intermediate organisms that can only reproduce in living cells since they lack the cellular machinery necessary for replication. They infect a host cell, take over the cell's machinery to replicate, and then release new viruses to infect other cells.
All living organisms need to make new cells to grow, repair damage, and replace old or dying cells in order to maintain their structure and function. This process also allows for genetic diversity and adaptation to changing environments.

1) all living things are composed of cells. 2) cells are the basic units of structure and function in living things. 3) new cells are produced from existing cells.
Old cells make new cells so that when the old ones die there are new ones to replace them.

The idea that living organisms arise from pre-existing living organisms is a key component of the cell theory. This principle is often summarized as "life from life," meaning that cells can only be produced by other living cells.
Viruses are the intermediate organisms that can only reproduce in living cells since they lack the cellular machinery necessary for replication. They infect a host cell, take over the cell's machinery to replicate, and then release new viruses to infect other cells.
The cell theory is a fundamental concept of Biology that states that all living things are composed of cells; that cells are the basic units of structure and function in living things; and that new cells are produced from existing cells.
All living organisms need to make new cells to grow, repair damage, and replace old or dying cells in order to maintain their structure and function. This process also allows for genetic diversity and adaptation to changing environments.
-all living things are composed of cells -cells are the basic unit of structure and function in living things -new cells are produced from existing cells
1) all life is composed of cells2) cells are the smallest living unit3) all cells come from pre-existing cellsThree statements which create Cell Theory are-All living organisms are made from cells either multicellular or unicellular.The cell is the basic unit of life.All cells exist from pre-existing cell.The modern version of the cell theory include the ideas thatEnergy flow occur within the cell.Hereditary information (DNA) is passed through one cell to other.All cells have the same basic chemical composition.
