The reproductive structure of gymnosperms. Strobili - normally known as 'cones' - are made up of a collection of modified leaves, but unlike flowering plants there are no colours or scents involved. The leaves become heavily lignified, which makes them tough, strong and waterproof. In between the leaves (or scales) can be found structures giving rise to pollen (in male strobili) or ovules (in female strobili). Over two or more years, the pollen is released, the ovules fertilised and the seeds slowly grow inside a cone. When the seeds are ready to be dispersed they are either shaken out by the wind from between the scales, or the entire cone is removed by animals (squirrels for example) to be eaten.
Reproductive organ of a conifer. Male resemble catkins, female resemble mature cones in miniature.
cone-shaped mass of ovule- or spore-bearing scales or bracts
Cone-like reproductive structure; spore-bearing structure of horsetails (Equisetaceae) and clubmosses (Lycopodiaceae; plural = strobili.)
a cone-shaped cluster of spore-bearing leaves
Cone-like reproductive structure with spores bearing appendages or scales.
terminal cluster of sporophylls or cone
A specialized reproductive structure consisting of a stem with short internodes and sporangium-bearing appendages, generally modified leaves called sporophylls, attached in a spiral pattern.
(pl strobili) A dense cone-like structure producing spores.
a 'cone' consisting of sporophylls borne close together on an axis.
The "cone" of conifers in which seeds or pollen grains are produced
A tightly clustered group of sporophylls arranged on a central stalk; commonly termed a "cone" or "flower".
A cone-like, spore-bearing reproductive structure of horsetails ( Equisetaceae) and clubmosses ( Lycopodiaceae). A specialized leaf-like organ on which one or more sporangia are borne close together on a main stem.
A strobilus (plural strobili) is an organ of many plants that contains the reproductive structures. Strobili are ordinarily called cones in many of these groups. Strobili are characterized by a central axis (anatomically a stem) surrounded by spirally arranged or decussate structures that bear sporangia or other reproductive parts.
