How do seeds compare to spores as dispersal units?

Question

Quizplus · Accepted Answer

Seeds have more resources for growth and establishment compared to spores, as they are multicellular and contain stored nutrients. However, this also makes seeds larger and heavier, requiring extra investment in tissues for dispersal. Spores are adapted for dispersal through wind or other means, but do not contain the same resources as seeds. Both seeds and spores can give rise to new individuals, but seeds do so by germinating and growing into a mature plant, while spores can develop into either haploid or diploid individuals depending on the organism's life cycle.
