Hello. I'm not sure if there is one or not, but what is the difference between pollen and spores? I honestly can't think of a single one.

 

 

Think in terms of what you need to grow a whole organism out of everyone. Also compare spores to seeds.

Pollen is a something which attend in creating a sporophyte on a gamethopyte.

Gamethopyte produces male (pollen) or female (ovules) gametes and if they fuse, sporophyte will comes into existence (it will grow on the gametophyte).

Sporophyte includes spores which are like seeds and if they fall into the soil (and have great terms), they will turn into a new plant.

So, in shorter version:

Pollen is a male gamete which attend in creating a sporophyte.

Spores are something like seeds (but they are more numerous than seeds) and they fill a sporophyte.

Sporophytes produce spores which become gametophytes that produce gametes (pollen/ ovum) which combine with other gametes (n- half genetic material) (fertilization) and make seeds which grow and become the next generation of sporophytes (2n).
