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.
There are four main types of plant propagation depending on the type of plant. Propagation methods include taking cuttings, dividing roots, sowing seeds and air layering. Which type of plant propagation method you use will depend on the type of plant you are trying to increase. Some plants can be propagated fairly easily in more than one way, eg strawberries which can be grown from seed also produce plantlets at the end of runners after the fruiting period.
