give ans and be the brainliest...i always mark..you can check my previous questions​

Answer 1

Answer:

The functionality of the basal body is also similar to the electrical motor and it helps to move the external flagella extensions for the locomotion process. Due to this structural and functional similarities ,this basal body is known as the smallest motor (biological) in the world.

• Major differences between Prokaryotic and Eukaryotic Cells.

The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. ... The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles.

Hey! Hope this helped you!!

Answer 2

Answer:

Basal body of the bacterial flagella has a similar structure to the modern electrical motors.

The functionality of the basal body is also similar to the electrical motor and it helps to move the external flagella extensions for the locomotion process.

Due to this structural and functional similarities ,this basal body is known as the smallest motor (biological) in the world.

Prokaryotes :

Type of Cell - Always unicellular

Cell size- Ranges in size from 0.2 μm – 2.0 μm in diameter    

Cell wall -Usually present; chemically complex in nature

Nucleus- Absent. Instead, they have a nucleoid region in the cell

Ribosomes  - Present. Smaller in size and spherical in shape  

Endoplasmic reticulum -Absent  

Plasmids -Present      

Ribosome    - Small ribosomes

Lysosom   -  Lysosomes and centrosomes are absent  

Cell division  - Through binary fission

Flagella  -  The flagella are smaller in size

Reproduction   - Asexual

Example -Bacteria and Archaea

Eukaryotes:

Type of Cell - Unicellular and multi-cellular

Size- ranges from 10 μm – 100 μm in diameter

Cell wall -When present, chemically simple in nature

Nucleus - Present

Ribosomes  - Present. Comparatively larger in size and linear in shape

DNA arrangement -Linear

Mitochondria - Present

Cytoplasm - Present, cell organelles present

Endoplasmic reticulum- Present

Plasmids - Very rarely found in eukaryotes

Ribosome  - Large ribosomes

Lysosome  -  Lysosomes and centrosomes are present

Cell division - Through mitosis

Flagella - The flagella are larger in size

Reproduction - Both asexual and sexual

Example - Plant and Animal cell
