Trillium grandiflorum in the foreground and the smaller Thalictrum thalictroides in the background are both spring ephemerals of North American deciduous forests. An ephemeral plant is a plant with a very short life cycle or very short period of active growth, often one that grows only during brief periods when conditions are favorable.
Plants whose life cycle is significantly less than the time of a growing season are deemed ephemeral. [37] Winter annuals, Epilobium and Senecio vulgaris are examples of ephemeral plants. [37] [38] The conditions for ephemeral plants are markedly present in deserts. [38] Animals can be ephemeral, with brine shrimp and the mayfly being examples.
The model proposes that auxin, a plant growth hormone, is synthesized in the coleoptile tip, which senses light or gravity and will send the auxin down the appropriate side of the shoot. This causes asymmetric growth of one side of the plant. As a result, the plant shoot will begin to bend toward a light source or toward the surface. [3]

Plant intelligence is a field of plant biology which aims to understand how plants process the information they obtain from their environment. [ 2 ] [ 3 ] Plant intelligence has been defined as "any type of intentional and flexible behavior that is beneficial and enables the organism to achieve its goal".
Vernal pools, also called vernal ponds or ephemeral pools, are seasonal pools of water that provide habitat for distinctive plants and animals. They are considered to be a distinctive type of wetland usually devoid of fish, and thus allow the safe development of natal amphibian and insect species unable to withstand competition or predation by ...
One definition for ephemera is "the minor transient documents of everyday life". [3] [4] Ephemera are often paper-based, printed items, including menus, ticket stubs, newspapers, postcards, posters, sheet music, stickers, and greeting cards. However, since the 1990s, the term has been used to refer to digital artefacts or texts. [5]
