what is cilia and flagella.....❤​

Answer 1

Answer :

Cilia and Flagella :-

• Both of them are hair like outgrowth of cell membrane.
• Cilia are small structures which help in the movement of materials.
• Flagella are comparatively longer and the responsible for cell movement.
• The prokaryotic bacteria possess flagella which are structurally different from the flagella that you eukaryotic organisms possess.
• Both of them emerge from centriole like structure called the basal bodies.
• Both of them are covered with plasma membrane and their core is called axoneme.
• The axoneme consist of microtubules parallel to each other.
• It usually have nine pairs of doublets of radially arranged peripheral microtubules and one is centrally located.
• Such an arrangement of of these microtubules is referred to as 9+2 array.
• The Central tubules in the axoneme are connected to the bridges which are enclosed by central sheath.
• These tubules is connected to each of the tubules of peripheral doublets by radial spoke. Thus, there is presence of 9 radial spokes.
• The peripheral doublets are connected by linkers.
