Some useful terms to know the differences between in order to make your life a lot easier!
Ovule vs ovulate cone vs ovary vs seed
Fertilization vs pollination
Sperm vs spore vs pollen
Gymnosperm vs angiosperm (differences other than “naked seed” and “covered seed”)
Archegonia/ antheridum vs archegoniophore/ antheridiophore
“epiphytes”  has to do with ferns
“Bryophytes” vs bryophyta
lycophytes vs Lycopoda
Best of luck!!!
