What is the anatomy of Calotropis stem?
Calotropis procera is an evergreen shrub that may grow up to 6 m (usually 2. CABI, 2021; Figure 2). Young stems are grayish-green in color, smooth, and pubescent, whereas the mature stems have a deeply fissured bark (Hassan et al. Abstract. Calotropis procera is a perennial flowering plant of the Apocynaceae family, traditionally used in medicine to treat various ailments. Recent investigations have revealed its potential therapeutic activities such as anti-inflammatory, gastroprotective, analgesic, anti-obesity, and anti-diabetic properties.Habit: Calotropis procera grows as a glabrous or pubescent, shrub to small tree up to 6 m in height. The leaves are oppositely arranged to 30 cm, obovate to suborbicular, with an entire margin and acuminate leaf apex.
What is the leaf arrangement of Calotropis plant?
In the case of Calotropis (a genus of flowering plants in the dogbane family), the phyllotaxy is opposite decussate. In an opposite decussate arrangement, pairs of leaves are arranged at right angles to the pair above or below them on the stem. This type of leaf arrangement is fairly common in many plant species. Phyllotaxy in Calotropis is opposite because leaves at the nodes are opposite from one another. At right angles, if the successive pairs of leaves are placed opposite to one another then the arrangement is called as Opposite decussate.The arrangement of leaves on a stem is known as phyllotaxy; leaves can be classified as either alternate, spiral, opposite, or whorled. Plants with alternate and spiral leaf arrangements have only one leaf per node.
What type of Placentation is Calotropis?
Placentation axile. Ovules 30–50 per locule (‘many’). Fruit and seed features. Fruit 70–120 mm long; dehiscent; 1 locular (in 2 follicles, with one often aborting). Note:The kind of placentation that a plant has with the kind of arrangement of the ovules will decide the arrangement of the seeds within the fruit. For instance in citrus fruits like the orange, we can see the partitions and the arrangement of the seeds in axile positions when the segments are cut into.
What is correct for arrangement of leaves on stems in Calotropis?
Hint: The pattern or distribution of the leaves on the stem or a branch of a plant is referred to as Phyllotaxy. The Calotropis is generally having the Phyllotaxy in which from the nodes of the stem, leaves are raised in the opposite direction. Phyllotaxy refers to the pattern or arrangement of leaves on the stem or branch of a plant. It is of three types, alternate, opposite, and whorled phyllotaxy.
