Answer:

The term “reptile” is derived (Made) from a Latin word meaning “creeping animals.” These animals include snakes, lizards, crocodiles, alligators, turtles, geckos, and chameleons, with lizards and snakes species making up the majority of all reptiles. Reptiles are cold-blooded animals which means they are unable to regulate their own body temperature. Reptiles are Oviparous (Egg laying). Reptiles also have chains of bony elements from the tail to the head. The bony endoskeleton consists of cranium or skull, appendages, and limb girdles. The endoskeleton protects the inner tissue and also aids in body movement. Skeletons differ from one species to another, with crocodiles having some of the largest body structures in this class.

Answer:

Movement will be brought about in touch me not plants by the action of various chemicals present at the base of the leaf stalk. 

Explanation:

The leaves of touch me not plant stay upright due to turgor pressure. It is exerted by the water present within its cells. This pressure applies force against the cell wall enabling the plant to remain stiff.

When there is an external disturbance , parts of the plant releases certain chemicals including potassium ions that causes water to diffuse out of cells. This releases the turgor pressure and causes the leaves to shrink.
