How are calotropis dispersed?
The fruit is a follicle and when dry, seed dispersal is by wind. The seeds with a parachute of hairs, is a delight for small children, who like to blow it and watch it float in the air. This plant plays host to a variety of insects and butterflies.
Which seeds is dispersed by animals?
Examples include mangoes, guavas, breadfruit, carob, and several fig species.

What is the mode of dispersal of okra fruit?
The seed pod starts drying out due to heat. This creates tension along the walls of the pod. Thus, the pod splits open, and the seeds are violently ejected in the air. Plants that disperse due to explosion are broom, euphorbia, geranium, okra, witch-hazel, etc.
What is the adaptation of calotropis?
Calotropis procera has an exceptional ability to adapt and maintain productivity in severe arid conditions (Ramadan et al., 2014). It is a C3 plant that can survive drought, salinity, extreme temperatures, high vapor pressure deficit, and high photosynthetic active radiations (Frosi et al., 2013; Rivas et al., 2020).
Is Cotton dispersed by explosion?
Name two plants whose seeds are dispersed by explosion of their fruits – Science – Reproduction in Plants. Cotton, Madar, and dandelion seeds are dispersed by wind. Some seeds are transported by wind, and have seeds designed to float, glide or spin through the air.

How does a Calotropis procera lucidcentral reproduce?
This plant reproduces mainly by seeds, though local increase in the size and density of populations also occurs via suckering from the roots. The seeds can be spread long distances by wind and water and can also be dispersed in mud that becomes attached to animals and vehicles.
What kind of aestivation does Calotropis gigantea have?
The aestivation found in calotropis is valvate i.e. sepals or petals in a whorl just touch one another at the margin, without overlapping. The plant has oval, light green leaves and milky stem. The latex of Calotropis gigantea contains cardiac glycosides, fatty acids, and calcium oxalate. The roots also contain Calotropone.
