The adult human skeletal system consists of 206 bones, as well as a network of tendons, ligaments and cartilage that connects them. Teeth are made of dentin and enamel and are part of the skeletal system but are not counted as bones.
Advantages-Spores are covered by a hard protective coat which enables them to survive under unfavourable conditions like lack of water and extreme temperatures.But when the conditions are favourable, the spores grow to produce new plants. This help them to run their species at any type adverse condition or environment.Thus the advantage is that despite of unfavourable environment, their species will not be demolished. Disadvantages-spore formation process is quite primitive.ach spore can survive for a long time since it is covered by a hard protective coat to withstand unfavorable conditions such as high temperature and low humidity. A spore germinates under favorable conditions and develops into a new individual. For example, Plants such as moss and ferns reproduce by means of spores.
spore. Hard shell-like protective encasement that enables some microorganisms (such as Clostridium) to survive bactericidal chemicals and extreme conditions of cold, heat, and dryness.A microorganism in spore form, although dormant, is much harder to kill than when it is in active form.Diseases caused by spores include anthrax, botulism, gas gangrene, and tetanus. Spores are destroyed only by sterilization. From Greek 'sporos,' seed. microorganism in spore form, although dormant, is much harder to kill than when it is in active form.
