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.
Asexual propagation. Plants have a number of mechanisms for asexual or vegetative reproduction. Some of these have been taken advantage of by horticulturists and gardeners to multiply or clone plants rapidly. People also use methods that plants do not use, such as tissue culture and grafting. Plants are produced using material from a single parent and as such there is no exchange of genetic material, therefore vegetative propagation methods almost always produce plants that are identical to the parent. Vegetative reproduction uses plants parts such as roots, stems and leaves.
