How will an organism be benefited if it reproduces through spores?
Spores are produced from sporangium, they do not require any medium for the dispersal and are light in weight, so can easily be transferred for germination. Spores can be remain alive but not actively growing till their favourable condition comes, they help organisms to survive or to get over the stress phase. Many spores can transferred at once, so reproduction is very quick, that’s why organisms are benifitted if they reproduces through spores. Major advantage is that spores are large in number, so population will also increases and survival chances are also high.
