Prokaryotic Cells And Eukaryotic Cells

Prokaryotic Cells and Eukaryotic Cells

These are types of cells, based On Structure Types Of Cell

Two types of cell based on structure
• Prokaryotic Cells
• Eukaryotic Cells

The word prokaryotic is formed by the combination of two Greek word - Pro and Karyon.

Pro means- Before, Karyon means- Nucleus, Prokaryotic means- Before Nucleus.

Such cells which lack a true nucleus are called prokaryotic cells.

• Prokaryotic cells are found in most unicellular organisms.

Like- Amoeba, Bacteria, Archaea, Cyanobacteria( Blue Green algae)

• Its size ranges from 1 micrometer to 10 micrometer.

• The respiratory system is located in the plasma membrane.

• The photosynthesis system is present in the membrane and chloroplasts are absent.

• It contains 70s types of ribosome.

• There is no sexual reproduction in them.

• In these, cell division occurs by fission or budding.

The word Eukaryotic is formed by the combination of two Greek word - EU and Karyon.

EU means- Well developed, Karyon means- Nucleus, Eukaryotic means- Developed Nucleus.

Such cells which a true nucleus (Developed Nucleus ) are called Eukaryotic cells.

• Eukaryotic cells are found in most multicellular organisms.

• Its size ranges from 10 micrometer to 100 micrometer.

• The respiratory system is located in the mitochondria.

• The photosynthesis system is present in chloroplasts.

• It contains 80s types of ribosome.

• There is sexual reproduction in them.

• In these, cell division occurs by Mitosis or Meiosis.
