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.
When they are separated from the plant, both seeds and spores eventually germinate. However, a seed germinates more easily than a spore because the latter requires a wet environment. 4. Seeds are disseminated by animals that eat the fruit of flowering plants, while spores simply fall off and may be spread by the wind.
