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.
Fundamentally, spores and gametes are very different. One difference is in the type of reproduction that each are involved in. Spores are used in asexual reproduction, while gametes are used in sexual reproduction.Another difference is in what each needs to develop into the next stage in the life cycle.A spore has the ability to grow into the adult gametophyte all by itself.he structure that produces a gamete is already haploid and so does not need to change the number of chromosomes it has in order to produce haploid gametes. So, hopefully this post explains how different spores and gametes are. I wanted to highlight this information because I see it as a common source of error.
