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.
Confidence votes 39. 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.lternation of generations is the term used to describe how spores  reproduce. This means, the spore is able to become a new plant or  organism from itself as a form of asex â¦ ual reproduction. The spore  comes from the original plant or organism to become a new life  form.
Spores are resistant to heat, UV radiation and chemicals because they are comprised of a tough proteinaceous covering called keratin. A mature endospore contains a complete set of the genetic material (DNA) from the vegetative cell, ribosomes and specialized enzymes.hen vegetative cells are subjected to environmental stresses such as nutrient deprivation they eventually die. However, some bacteria such as the Bacillus spp. and the Clostridium spp can circumvent the problems associated with environmental stress by forming. endospores. .
