Meissner’s corpuscles and Merkel’s disks are types of tactile mechanoreceptors. They have gated ion channels which open and close in response to pressure, touch sound. Meissner’s corpuscles are fast adapting, encapsulated neurons whereas, Merkel’s disk are slow-adapting, non-capsulated neuron. They responds to vibrations and fine touch; they are located in the skin where there is no hair such as the palms and fingers.

Some flowers are bilaterally symmetrical or zygomorphic or mono-symmetric as in these flowers only possible to draw a single line of symmetry through them. Whereas some flowers are radially symmetrical or actinomorphic or poly-symmetric. In them, many lines of symmetry can be drawn. Besides, some flowers are asymmetrical.
Orchid flowers show extreme bilateral symmetry. In Daisy flowers head or capitulum is radially symmetrical capitulum and ray florets are bilateral symmetry. Rose flower is radially symmetrical and <em>Wisteria</em> flowers are bilaterally symmetrical.
