HORTICULTURE

Detailed explanation-1: -In fern, spores are formed in sporangium. The plants of Pteridophytes are sporophytes . They reproduce asexually by forming spores in sporangia. In ferns an unbranched sporophyte produces sporangium, which may be quite complex morphologically.

Detailed explanation-2: -Spores are produced in capsules called sporangia. Most ferns produce 64 spores in each sporangium. Sporangia are aggregated into clusters called sori. When mature, the spores are released from the sporangia.

Detailed explanation-3: -The fern life cycle Mature plants produce spores on the underside of the leaves. When these germinate they grow into small heart-shaped plants known as prothalli. Male and female cells are produced on these plants and after fertilisation occurs the adult fern begins to develop.

Detailed explanation-4: -The second form of asexual reproduction occurs by spores. These form on the undersides of the leaves in spore cases called sporangia.

Detailed explanation-5: -The sporangia is the structure which produces spores. In ferns, the sporangia are usually aggregated into particular bigger structures.
