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).
<u>Explanation:</u>
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,
- All organisms are made up of one or more cells.
- Cells arise from other cells.
- 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.
<u>Types of cells:</u>
The cells are classified as Eukaryotes Cell and Prokaryotes Cell
- Presence of Mitochondria
- Presence of Cytoskeleton
- Presence of Membrane-bound Nucleus
Examples: Animals and plants
- Absence of Mitochondria
- Absence of Cytoskeleton
- Absence of Membrane-bound Nucleus
Examples: Bacteria
The correct answer is immediate passive short-term immunity.
The tetanus immunoglobulin comprises of readymade antibodies and provides short-term passive immunity. The passive immunity signifies to the procedure of offering immunoglobulin antibodies to defend against the infection.
It provides instantaneous, however, short-lived safeguarding, that is, for many weeks to three or four months at maximum. Passive immunity is categorized as acquired or natural.
The answer is transverse or t tubules. These invaginations into the skeletal muscles cells play a significant role in electrical conductivity of impulse across muscle or cardiac fibres. They regulate calcium concentration and it's release in ion channels hence enabling a forceful contraction of cardiac and muscle cells.
