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.
Although sexual reproduction is common in plants, most also reproduce asexually through what is commonly called vegetative propagation. There are a number of plant tissues capable of this process, for example rhizomes (potato), runners (strawberry), stem pieces (willow), and seed (dandelion).Vegetative reproduction is a type of asexual reproduction without seeds or spores, and it occurs in plants.unners or stolons is used for natural vegetative reproduction. Strawberries, grasses and some ferns are examples of runners or stolons. The strawberries and the grasses spread stem stems horizontally everywhere.
