Seeds
A cluster of spore-bearing structures called the strobilus is typically found in certain plants, particularly in gymnosperms like conifers and in some ferns. The strobilus, often referred to as a cone, contains reproductive organs where spores are produced and released for reproduction. In conifers, male strobili produce pollen, while female strobili develop seeds. This adaptation allows these plants to effectively reproduce and disperse their genetic material.
Sporangium
Ferns do not produce seeds enclosed in little cases like flowering plants. Instead, ferns reproduce through spores that are found on the underside of their fronds in structures called sporangia. These spores are released into the environment and germinate to grow into new fern plants.

Ferns and Mosses
Not at all. Ferns are one of the world's most adaptable plants, found in a variety of conitions and continents.
Spore cases, also known as sporangia, are typically found on the reproductive structures of fungi, mosses, ferns, and some plants. In ferns, they are often located on the underside of leaves in clusters called sori. In fungi, spore cases can be found on specialized structures such as mushrooms or other fruiting bodies. The location varies depending on the organism and its reproductive strategy.
In ferns, the spore casings are called sporangia. These structures are typically found on the undersides of leaves (fronds) and can be grouped together in clusters known as sori. When mature, sporangia release spores that can develop into new fern plants.
Antheridia are structures in seedless plants that produce sperm. They are typically found on the gametophyte generation of plants like ferns and mosses. Within the antheridia, sperm cells are produced through a process of spermatogenesis.
Plants found in DRC are mahogani , Venus flytrap , Ferns , Kapok , Bromeliads , Orchids .
The spore cases of ferns are typically found on the undersides of the fronds, in structures called sori. These sori contain the spore-producing structures known as sporangia.
In lower plants, such as mosses and ferns, gametes are produced in specialized structures called gametangia. Male gametangia, known as antheridia, produce sperm, while female gametangia, called archegonia, produce eggs. These structures are essential for sexual reproduction in these non-vascular plants.
