What helps the lizard to attach to the wall?
Answers
Answer:
It's actually pretty incredible. The structure of their toes is such that they have lots of little “flaps” of skin, each of which contains lots of little fibres, called setae. They're smaller than hairs, and stick out a microscopic amount from the skin of the toe. These fibres actually have a chemical reaction with the surface they climb on, utilizing Van der Waals force to create an attraction between the molecules of their toes and the molecules of the wall.
Explanation:
LIZARDS HAVE PADS ON THEIR FEET THIS PADS CONSIST OF WIDE PLATE OR SCALE ARE PRESENT BELOW THEIR FINGER AND TOES .THE OUTER LAYER OF EACH PLATE IS COMPOSED OF INNUMERble tinY HOOKS OR MED BY FREE BENT TIPS OF CELLS . THIS MINUTE HOOKS CREATE THE CONDITIONS LIKE A SUCTION PUMP AND THUS, ENABLE LIZARDS TO RUN UPON THE APPERENTLY SMOOTH WALLS AND EVEN UPSIDE DOWN ON PLASTER CEILINGS .
BECAUSE THIS HOOK LIKE CELL ARE BEND DOWNWARD AND TO THE REAR , THE LIZARD CURLS ITS TOES UPWARDS TO DISENGAGE THEM .THUS WHILE WALKINH OR RUNING OR HORIZONTAL OR VERTICAL WALLS , A LIZARD CURLS AND UNCURLS IT TOES THUS CREATING A SUCTION PRESSURE WHICH WHICH ENABLES ITS TO CLING ON TO THE WALLS
