A male cone (microsporangiate strobili) of a conifer that supports and protects the pollen of the plant.
A staminate flower, with or without a perianth, that has only functioning male reproductive parts, or if female reproductive parts (pistils) are present, they are non-functioning.
An phase in some plant species where leaves/needles take on a different shape (morphology) as the perennial plant ages. This species have "dimorphic" leaves. Some junipers fit into this category, as do some broadleaf species (Hedera helix (English ivy), Ficus pumila (creeping fig)).
A bract or modified leaf tissue that supports the megasporangium or developing ovule (in the case of gymnosperms - such as the bract of a pinecone/seedcone).
Undifferentiated cells in actively dividing plant tissue, found in the zones where growth takes place - such as at the tips of shoots and roots (apical), in buds and nodes of stems (apical), along grass leaves and stems (intercalary), in cambium (vascular and cork), and in a layer of cells in roots (pericycle)
A type of habitat with a moderate or well-balanced supply of moisture, i.e. a mesic forest, a temperate hardwood forest, or dry-mesic prairie.
Conventionally described as data about data, metadata can be more accurately defined as structured information that describes, explains, locates, or otherwise makes easier to use or manage an information resource.
A minute opening on the ovule through which the pollen tube usually enters; the scar upon a seed which was the opening in the ovule
A bract or modified leaf tissue that supports the microsporangium or developing pollen (in the case of gymnosperms - such as the tiny bract in pollen cone)
The central or principal rib of a leaf
The central or principal vein of a leaf
A plant species that flowers and produces fruit just once and then dies (its typical life cycle); can be applied to annuals, biennials, and perennials
plant that reproduces one time and then dies.
A plant species that has a single seed leaf (cotyledon)
A plant or plant species that has separate male/staminate and female/pistillate flowers (imperfect flowers (unisexual)) that occur on the same plant
The study of an organism's form and structure
A fruit that has developed from more than one flower, in which the flowers are tightly clustered, and mature into a tight cluster of individual fruits (such as mulberry, pineapple, fig, osage orange). This differs from an aggregate fruit which derives a single flower. (Fig is a rather unusual inflorescence and fruit, see synconium.)
