This type of muscle is found solely in the walls of the heart. It has similarities with skeletal muscles in that it is striated and with smooth muscles in that its contractions are not under conscious control.However this type of muscle is highly specialised.t has similarities with skeletal muscles in that it is striated and with smooth muscles in that its contractions are not under conscious control.

Plants can propagate using either sexual reproduction or asexual reproduction. The various types of vegetative propagation are examples of asexual reproduction. The offspring of the plants are clones of the original plant since no mixing of DNA occurs. The most common forms of vegetative propagation are grafting, cutting, layering, tuber, bulb or stolon formation, suckering and tissue culture.
Plant grafting is a technique in which tissue from one plant, the scion, is attached onto another, the rootstock. The rootstock produces new vascular tissue with which to feed the scion, and the graft heals.hree common methods are approach grafting where the stems from two different plants are attached together, T budding where a bud from the scion is nestled into the stem of the rootstock, and cleft grafting where the stripped end of the scion is placed into a cleft made in the rootstock.
