Key Difference Between Prokaryotic cell and Eukaryotic cell with Label Diagram?

Difference Between Prokaryotic cell and Eukaryotic cell :

Difference Between Prokaryotic cell and Eukaryotic cell. Cell is the basic structural and functional unit of all the living organism except virus. A single cell is composing of a protoplasm a boundary the member and genetic material. Cell consists of many organelles. Organelles make a special structure of cell and help the cells to perform many functions. There are two types of organelles. One is membranous Organelles and second is Non-membranous Organelles.

On the base of organelles cell is divide into two Group. e.g. Prokaryotes and Eukaryotes.

Prokaryotes:

Prokaryotes are group of those organism that make up of Prokaryotic cells. Prokaryotic cells are very primitive cell in morphological point of view. There have no well defined nucleus and many major organelles such as Golgi complex, endoplasmic reticulum, mitochondria and centriole etc.

In other word you can say prokaryotic cells have no membrane bound organelles. In Prokaryotic cell genetic material (chromosome) is bounded in a portion of cytoplasm that called nucleoid.

Eukaryotes:

Eukaryotes are group of those organism that make up of Eukaryotic cells. Eukaryotic cells consist of plasma membrane and membrane bounded organelles such as Golgi complex, endoplasmic reticulum, mitochondria and centriole etc. They have well defined nucleus.

 In animals and plant various types and shape of cells exhibit. In animals mostly, cells are spherical in shape, in plants its shape is rectangular. The shape of cells differs from animal to animals. There is a correlation between the size, shape of the cell according to their function.

FromUnicellular or filamentous in form. Unicellular or truly multicellular in nature.
Genetic MaterialNo true nucleus present in it. DNA laying naked in cytoplasm. True nucleus present in it. DNA associated within the protein.
Protein SynthesisSmaller Ribosome (70s). No endoplasm recticul involve for protein synthesis.Lager Ribosome (80s). This ribosome attach with ED.
organellesFew organelles are present . They have no member outside (Non membrane bounded organelles).Many organelles are founded.All organelles are membrane bounded. such mitochondria, Golgi complex etc.
Cell WallRigid and compose with amino acid and polysaccharide. Murine is the main component of cell wall they strentn to cell wall.Cell wall of fungi and plant are rigid and compose of polysaccharide material.cellous is the main component of cell wall that give strength to plant and chitin is main component of fungal wall.
Flagella Very simple not cover by any membrane and microtubule also absent in it. The size 20um. Complex in nature, 9+2 arrangement of microtubules are occurred. Its cover by outer membrane. Its diameter is 200um.
Respiration
In bacteria respiration occur through mesosoma, except cytoplasmic membrane in blue green algae.
 
In which aerobic respiration through mitochondria .
PhotosynthesisChloroplast is absent. Photosynthesis occur through member which show no stacking.
Chloroplast is present in member which have stack of grana.
Nitrogen FixationFew Have the ability to fix the nitrogen.No one have the ability to fix Nitrogen.

Introduction to Zoology, History, Branches and Sub Branches of Zoology:

What is Zoology?

zoology is defined as a branch of biology that focuses entirely on the study of animals.

The field of zoology dates to the Ancient Greeks when zoologists made attempts to classify different types of animals based on certain criteria.

History of Zoology:

Modern-day zoology is based on the works of Charles Darwin and other scientists who developed theories after using a microscope and other scientific instruments to draw more accurate conclusions. The field of zoology and the standard zoology description continues to evolve and become more complex over time.

Introduction to Zoology:

Zoology is a major division of biology and broad Includes the study of animal life including animal’s internal functions and cells Study in this field typically requires performing a variety of experiments with animals, in both lab and non-lab environments.

Introduction to Zoology and its Branches May include breeding, raising animals in controlled conditions, and testing the effects of different types of drugs on different types of species.

Zoologists may use computerized information to test scientific methods May include the study of just one group of animals.

Specializations include animal taxonomy, animal physiology and embryology.

Since zoology is such a broad field, many students who are studying zoology or declaring a zoology major choose to specialize in one of the branches of zoology.

Zoology branches include everything from the study and form of animals, the interrelationships of animals from the past and present.

The study of earth and life, the study of extinct animals and fossils, and the development of the egg after fertilization in a certain species.

When you are exploring the subject of zoology and considering majoring in this field, take the time to learn about different zoology branches to see what area is of most interest to you.

Remember that zoologists and researchers must study their subjects for several years before they can find gainful employment.

In fact, you will need at least a doctoral degree to apply for research positions or teaching positions in this field.

Choosing zoology branches that you are passionate about or very interested in learning about can help you stay motivated for this long educational track, and help you decide what to specialize in.

General Branches of Zoology :

Some of the general branches of zoology include:

Histology: The study of the structure and function of the tissues.

Morphology: The study of formation and structure of animals.

Cytology:  The study of the internal structure of animals.

Embryology: The study of the development of the egg after fertilization.

Physiology: The study of the different functions of various organs in the body.

Genetics:  The study of heredity and variations.

Ecology: The study of the relationship between different animals, organisms and the surrounding environment.

Geology: The study of earth and life as recorded by fossils in rocks.

Animal-Specific Branches of Zoology:

Since zoology encompasses the study of Introduction to Zoology and its Branches, fish, insects, crustaceans and other organisms, zoology branches can also be broken down by a specific species or type of animal.

Some of the animal-specific branches of zoology include:

Parazoology: The study of sponges.

Protozoology: The study of unicellular organisms.

Nematology: The study of nematodes.

Cnidology: The study of coelenterates.

Helminthology: The study of parasitic worms.

Entomology: The study of insects.

Torpedology: The study of skates and rays.

Carcinology: The study of crustaceans.

Myrmecology: The study of ants.

Lepidopterology: The study of butterflies and moths.

Conchology: The study of mollusks.

Batrachology: The study of frogs.

Some other Branches of Zoology :

Some branches of zoology are centered around the study of certain organs and diseases. Others fall under the category of “applied branches”, and include branches such as eugenics, poultry, apiculture and aquaculture.

Therefore Some of the other zoology branches that you may have an interest in when studying zoology or attending a zoology school, consist of following that given below:

Phenology: The study of animals as they are affected by seasonal changes.

Phrenology: The study of mental faculties of the brain.

Epidemiology: The study of the transmission of diseases.

Ethology: The study of animal behavior.

Teratology: The study of disease of embryos.

Pharmacology: The study of the effects of medicines and organisms.

Immunology: The study of immunity to diseases.

Exobiology: The study of existence of life in outer space.

Cryobiology: The study of the effects of low temperatures on certain organisms and species.

If you are interested in declaring a zoology major during college, you will need to enroll in a Bachelor of Science program with a concentration in biology, natural science, chemistry, cell biology and microbiology.

You will then need to complete graduate studies where you can declare a zoology major, and/or take a number of courses in a specialized field.

It won’t be until your doctoral level work that you can start doing more in-depth research products and fulfill many of the requirements listed on a zoology description for a job or career in the field.

Keep in mind that your career prospects will be better when you do decide to specialize in a certain field.
