Spores

Reproductive cells produced by fungi, plants (such as ferns), and some microorganisms, capable of developing into a new individual without sexual fusion.

Gametophyte

A stage in the life cycle of plants and algae that is haploid and produces gametes for sexual reproduction.

Antheridia

Male gametophyte structures in plants where sperm are produced.
