Question

How does the cell theory demonstrate this definition of theory

Answer 1

In simple terms, Cell Theory can be expressed as living organisms are composed and consists of cells and it arises from the surviving cells (existing cells).

Explanation:

Cell Theory:

• The term "Cell Theory" has created an impact in the biology field and it is now  confirmed that cell provides the basic structure to the living organisms and  Robert Hooke started doing researching  about the cells.

Principles of cell theory:

   The three principles to the cell theory are listed here,

1. All organisms are made up of one or more cells.
2. Cells arise from other cells.
3. The Cell is  the fundamental unit of structure and organization.

Contribution to Cell Theory:

• Schwann and Schleiden  are the two scientists who discovered lots of information about the cells and they have contributed lots to cell theory.
• Schleiden  states that  every part of plants are consists of cells and he states that cells were done by the  crystallization process.
• Schwann  states that  every part of plants and animals were consists of cells.
• Based on their contribution postulates of cell theory has been proposed.

Types of cells:

The cells are classified as Eukaryotes Cell and Prokaryotes Cell

• Eukaryotes:

1. Presence of Mitochondria
2. Presence of Cytoskeleton
3. Presence of Membrane-bound Nucleus

    Examples: Animals and plants

• Prokaryotes:

1. Absence of Mitochondria
2. Absence of Cytoskeleton
3. Absence of Membrane-bound Nucleus

     Examples: Bacteria
