In order to prevent the development of lycopod sporangia, sporophylls structures should be removed.
A leaf that generates spores is called a sporophyll. Sporophylls are a type of diploid sporophyte that produce spores that, upon germination, will give rise to haploid gametophytes. In sporangia, which can appear in a variety of shapes in diverse plant species, the spores are born. The sporophylls themselves differ significantly in terms of both structure and appearance, and they may or may not resemble trophophylls, which are leaves that only perform photosynthesis to create carbohydrates and never spores. Sporophylls and trophophylls are both green and photosynthesize in more primitive plants like lycophytes and ferns, and they typically resemble one another quite a bit. The sporophylls and trophophylls of certain unusually primitive plants, like Equisetum, as well as more evolved plants, such seed plants, are quite distinct from.
