The cell is the basic functional and structural unit of life. All the living organisms are composed of cells. All cells are formed by the division of the already existing cells which in terms of biology means reproduction. Every cell of our body comprises of genetic material which is passed down during the process and you will know much more about a cell in this video.

introduction to cell biology
Cell Biology
The cell is a chemical system that can maintain its structure and reproduce.
Cells are the fundamental unit of life.
All living things are cells or composed of cells.
The interior contents of cells in the cytoplasm
The cell is a chemical system that can maintain its structure and reproduce.
Cells are the fundamental unit of life.
All living things are cells or composed of cells.
The interior contents of cells in the cytoplasm.
Cell, in biology, the basic membrane-bound unit that contains the fundamental molecules of life and of which all living things are composed.
A single cell is often a complete organism in itself, such as a bacterium or yeast.
Other cells acquire specialized functions as they mature.
These cells cooperate with other specialized cells and become the building blocks of large multicellular organisms, such as humans and other animals.
The smallest known cells are a group of tiny bacteria called mycoplasmas; some of these single-celled organisms are spheres as small as 0.2 μm in diameter.
Largest cell ….
The largest single-celled organism is an animal
called Syringammina fragilissima, which can grow to a width of 4 inches.
– are highly folded, forming a complex network of tubes.
The biological science which deals with the study of structure, function, molecular organization, growth, reproduction, and genetics of the cells, is called cytology or cell biology
(Gr., kytos = hollow vessel or cell; logos = to discourse).
Much of cell biology is devoted to the study of structures and functions of specialized cells.
Individual cells that form our bodies can grow, reproduce, process information, respond to stimuli, and carry out an amazing array of chemical reactions.
Human body comprises of 100 trillion live cell. Cell becomes sick lack of Nutrition. Cell needs only six nutrition.Six nutrition are Amino Acid, Fatty Acid, Glucose, Vitamins, Mineral & Water This six nutrition only come from plant. Human cell food comes from Kitchen room . All nutrition is burned by over cooking & heating.So.ultimately cell don't get nutrition from our oral food.Not getting nutrition day after day cell becomes sick but toxin food is continuing .Cell becomes more sick.Then Cell gets synthetic drug instead of nutrition. Second death of cell is confirmed drug medications.Drug has no power for curing any disease but natural plant food has ability for curing any disease.

Guided notes covering material from Topic 1.1 of the updated IB Biology syllabus for 2016 exams. Notes sequence and prompts are based on the Oxford IB Biology textbook by Allott and Mindorff.
1.
Cell theory
1.1 Introduction to Cells
Cells & Biomolecule
Theory that states that all
organisms are composed of
cells, cells are the smallest
independent unit of life and
that all cells come from pre-
existing cells.
Differentiation
1.1 Introduction to Cells
Cells & Biomolecule
The alteration of a cell’s
morphology and physiology
through changes in gene
expression.
Emergent property
1.1 Introduction to Cells
Cells & Biomolecule
A property of a system that
emerges from the
interaction of the elements
of the system, where the
whole is more complex than
the sum of its parts.
Growth
1.1 Introduction to Cells
Cells & Biomolecule
An increase in physical size.
2. Homeostasis
1.1 Introduction to Cells
Cells & Biomolecule
The process in which an
organism regulates activities
within cells and their bodies
to keep conditions stable.
Magnification
1.1 Introduction to Cells
Cells & Biomolecule
Ratio of image size to actual
size.
Metabolism
1.1 Introduction to Cells
Cells & Biomolecule
The sum of all of the
chemical reactions that
occur within an organism or
within a cell.
Paramecium
1.1 Introduction to Cells
Cells & Biomolecule
Genus of single-celled
ciliated organisms that show
all signs of life.
3. Response
1.1 Introduction to Cells
Cells & Biomolecule
In behavioural science, the
behaviour that is the
consequence of a stimulus.
Scale bar
1.1 Introduction to Cells
Cells & Biomolecule
A means of visually
indicating the magnification
of an image.
Stargardt’s disease
1.1 Introduction to Cells
Cells & Biomolecule
A degenerative eye disease
that has been the target of
stem cell therapy.
Stem cell
1.1 Introduction to Cells
Cells & Biomolecule
A relatively undifferentiated
cell that can give rise to
other types of cells and
retains the ability to divide.
4. Surface area to
volume ratio
1.1 Introduction to Cells
Cells & Biomolecule
A variable that decreases as
cells grow, so that it sets a
limit to the size of cells.
System
1.1 Introduction to Cells
Cells & Biomolecule
A level of organization that
emerges due to the
interaction of elements.
Tissue
1.1 Introduction to Cells
Cells & Biomolecule
A group of cells with a
common function and
structure.
