On the basics of structure cell are two basic types.

Prokaryotic cell

The cell having nuclear material without nuclear membrane , are termed as prokaryotic cells,

These are generally small are not very complex in structure.

These are essential in folding of cell membrane.

In prokaryotes, nuclear region (containing only nucleic acids), called nucleoid of the cell maybe poorly defined due to the absence of a proper nuclear membrane.

Prokaryotic cells also lack most of the Other cytoplasmic organelles present in the Eukaryotic cells . i.e, prokaryotic cells are present in bacteria like E.coli, clostridium, blue green algae,etc.

Eukaryotic cell

The cells, like onion cells and cheek cells, having well organised nucleus with a nuclear membrane, are termed as eucaryotic cells.

This cells are more Complex than prokaryotic cells.
Close in eukaryotes is separated from the cytoplasm by double layered membrane.
And it directs the life process of the cell i.e, eukaryotic cells present in Protista, fungi, land animals.
All eucaryotic Cells are not identical such as plant and animal cells are different in having an additional layer, called cell wall ,around the cell membrane.

Difference between prokaryotic cell and Eukaryotic cell.

Prokaryotic cell

1. Generally smaller in size
2. It is not well defined
3. DNA is circular and lies free in cytoplasm (no true nucleus)
4. Lack organelles like endoplasmic reticulum , mitochondria, centrosome,etc.

5. Sap vacuoles are lacking. Gas vacuole maybe present.

6. Ribosome 70s( 3oS+50S).

7. Endocytosis and exocytosis do not occur in prokaryotes.

8. Cell cycle is short, of nearly about 20 to 60 minutes.

9. There is no nucleolus.

Eukaryotic cell

1. Generally larger in size.

2. It is well defined and surrounded by a nuclear membrane.

3. DNA is linear and content in A nucleus

4. Content organised like endoplasmic reticulum ,mitochondria, Golgi apparatus, lysosomes ,centrosomes,etc.

5. sap vacuole are commonly present .

6. They are 80S(40S+60S).

7. Endocytosis and exocytosis occur in many protist and in animal cells.

8. Cell cycle is long up about 12 to 24 hour.

9. One or more nucleoli to occur within the nucleolus.

difference between procaryotic and eucaryotic,in hindi,

Types of cells ( To read in this post in English click here) ( To read in details click here) संरचना की मूल बातें सेल दो बुनियादी प्रकार हैं। Procaryotic cell परमाणु झिल्ली के बिना परमाणु सामग्री वाले सेल को प्रोकैरियोटिक कोशिकाओं के रूप में कहा जाता है, ये आम तौर पर छोटे होते हैं संरचना में बहुत जटिल नहीं होते हैं। ये कोशिका झिल्ली की तह में आवश्यक हैं। प्रोकैरियोट्स में, परमाणु क्षेत्र (केवल न्यूक्लिक एसिड युक्त), जिसे सेल का न्यूक्लियॉइड कहा जाता है, शायद एक उचित परमाणु झिल्ली की अनुपस्थिति के कारण खराब परिभाषित किया गया है। प्रोकैरियोटिक कोशिकाओं में यूकेरियोटिक कोशिकाओं में मौजूद अन्य साइटोप्लाज्मिक ऑर्गेनेल की भी कमी होती है। यानी, प्रोकेरियोटिक कोशिकाएं ई.कोली, क्लोस्ट्रीडियम, ब्लू ग्रीन शैवाल, आदि जैसे बैक्टीरिया में मौजूद होती हैं। Eucaryotic cell एक परमाणु झिल्ली के साथ अच्छी तरह से संगठित नाभिक होने वाले प्याज कोशिकाओं और गाल की कोशिकाओं जैसे कोशिकाओं को यूकैरियोटिक कोशिकाएं कहा जाता है। यह कोशिकाएं प्रोकैरियोटिक कोशिकाओं ...

difference between procaryotic and eucaryotic, procaryotic, eucaryotic,all in details.

Procaryotic and eucaryotic cells Procaryotic cells & eukaryotic cells are the two types of cells that exist on Earth. There are several differences between the two, but the biggest distinction between them is that eukaryotic cells have a distinct nucleus containing the cell's genetic material, while prokaryotic cells don't have a nucleus and have free-floating genetic material instead. From prokaryotic cells to eukaryotic cells All living things can be divided into three basic domains: Bacteria, Archaea and Eukarya. The primarily single-celled organisms found in the Bacteria and Archaea domains are known as prokaryotes. These organisms are made of prokaryotic cells — the smallest, simplest and most ancient cells. Organisms in the Eukarya domain are made of the more complex eukaryotic cells. These organisms, called eukaryotes, can be unicellular or multicellular & include animals, plants, fungi & protists. Many people are unclear on whether yeasts ...

Cartosat,details about cartosatin hindi,English,ISRO.

Details about' CARTOSAT' ISRO(Indian space research organisation) Successfully Launches Cartosat-3 Earth Imaging Satellite; Touches 310 Foreign Satellite Launch-mark ISRO (Indian space research organisation)has successfully placed its earth observations satellite, Cartosat-3, in orbit. It has also launched 13 American nanosatellites like a textbook style. India has launched a total of 310 foreign satellites till date for a fee. The Cartosat-3, India’s new earth observation satellite will send sharp clarity images for urban planning, rural resource and more purpose. It will also send images of coastal land use and land cover, infrastructure development, all of which will helps in a strategic and defence purposes. ISRO said that they will provide the required images to various agencies. It is for the user agency to decide on the images use. The images captured by the satellite can also be used for surveillance purposes, ISRO has not said anything about ...
