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.
Learn How to Air Layer. When it comes to vegetative propagation, I naturally think of taking a plant cutting and rooting it in the ground or in some other media. But air layering is different: Itâs done aboveground while the propagule (a bud, tuber, root or shoot) is still attached to the parent plant.
