Kalanchoe pinnata, commonly known as cathedral bells, air plant, life plant, miracle leaf, [2] Goethe plant, [3] and love bush, [4] is a succulent plant native to Madagascar.It is a popular houseplant and has become naturalized in tropical and subtropical areas.
In addition, leaves produced during early growth tend to be larger, thinner, and more irregular than leaves on the adult plant. Specimens of juvenile plants may look so completely different from adult plants of the same species that egg-laying insects do not recognize the plant as food for their young.
The leaves of tricussate plants such as Nerium oleander form a triple helix. The leaves of some plants do not form helices. In some plants, the divergence angle changes as the plant grows. [22] In orixate phyllotaxis, named after Orixa japonica, the divergence angle is not constant. Instead, it is periodic and follows the sequence 180°, 90 ...
The trunk roots of Cryosophila guagara grow downwards to a length of 6–12 cm, then stop growing and transform into a spine. [5] The anatomy of crown roots on this species (roots among the bases of the living fronds) also alters during their life. [5] They initially grow upwards and then turn down and finally they, too, become spinous. [5]
Leaf margins have spoon-shaped bulbiliferous spurs which bear plantlets which may form roots while still attached to leaves. [6] A plant may also develop lateral roots on its main stalk, as high up as 10–15 cm (3.9–5.9 in) above the ground. A plant's upper leaves may grow large, causing its main stalk to bend downward.
Chloroplasts (green discs) and accumulated starch granules in cells of Bryum capillare. Botanically, mosses are non-vascular plants in the land plant division Bryophyta. They are usually small (a few centimeters tall) herbaceous (non-woody) plants that absorb water and nutrients mainly through their leaves and harvest carbon dioxide and sunlight to create food by photosynthesis.
Heliotropism, a form of tropism, is the diurnal or seasonal motion of plant parts (flowers or leaves) in response to the direction of the Sun. The habit of some plants to move in the direction of the Sun, a form of tropism, was already known by the Ancient Greeks. They named one of those plants after that property Heliotropium, meaning "sun turn".
Variation in leaves from the giant ragweed illustrating positional effects. The lobed leaves come from the base of the plant, while the unlobed leaves come from the top of the plant. Although plants produce numerous copies of the same organ during their lives, not all copies of a particular organ will be identical.
