Tendril. In botany, a tendril is a specialized stem, leaf or petiole with a threadlike shape used by climbing plants for support and attachment, as well as cellular invasion by parasitic plants such as Cuscuta. [1] There are many plants that have tendrils; including sweet peas, passionflower, grapes and the Chilean glory-flower. [2]
Helical growth is when cells or organs expand, resulting in helical shaped cells or organs and typically including the breakage of symmetry. This is seen in fungi, algae, and other higher plant cells or organs. [1] Helical growth can occur naturally, such as in tendrils or in twining plants. Asymmetry can be caused by changes in pectin or ...
Cladodes. Aerial stem modifications are modifications to the aerial stems, [1] vegetative buds and floral buds of plants growing in different conditions and which perform functions such as climbing, protection, support, synthesis of food, or vegetative propagation. [2][3] Aerial stem structures that undergo modifications to perform these ...
Thigmotropism. Redvine (Brunnichia ovata) tendrils coil upon contact. In plant biology, thigmotropism is a directional growth movement which occurs as a mechanosensory response to a touch stimulus. Thigmotropism is typically found in twining plants and tendrils, however plant biologists have also found thigmotropic responses in flowering plants ...
Thigmomorphogenesis. Thigmomorphogenesis (from Ancient Greek θιγγάνω (thingánō) to touch, μορφή (morphê) shape, and γένεσις (génesis) creation) is the response by plants to mechanical sensation (touch) by altering their growth patterns. In the wild, these patterns can be evinced by wind, raindrops, and rubbing by passing ...
In botany, apical dominance is the phenomenon whereby the main, central stem of the plant is dominant over (i.e., grows more strongly than) other side stems; on a branch the main stem of the branch is further dominant over its own side twigs. Plant physiology describes apical dominance as the control exerted by the terminal bud (and shoot apex ...
Gloriosa are herbaceous perennials that climb or scramble over other plants with the aid of tendrils at the ends of their leaves and can reach 3 meters in height. They have showy flowers, many with distinctive and pronouncedly reflexed petals, like a Turk's cap lily, ranging in colour from a greenish-yellow through yellow, orange, red and sometimes even a deep pinkish-red.
Ampelopsis glandulosa is a deciduous, woody, perennial climbing vine with flowers and tendrils opposite the palmately lobed leaves, which have three to five more or less deep lobes and coarsely toothed margins (with a small apicle). Porcelain berry climbs via tendrils to a height of 4 to 6 metres (13 to 20 ft).
