Coconut

The coconut palm is grown throughout the tropical world, for decoration as well as for its many cooking and non-culinary uses, virtually every part of the coconut palm has some human use.The flowers of the coconut palm are polygamomonoecious, with both male and female flowers in the similar inflorescence. Flowering occurs continuously, with female plants producing seeds. Coconut palms are believed to be largely cross-pollinated, although some dwarf varieties are self-pollinating. Coconut water can be used as an intravenous fluid.
Nearly all parts of the coconut palm are useful, and the palms have a comparatively high yield, it therefore has important economic value. The name for the coconut palm in Sanskrit is kalpa vriksha, which translates as the tree which provides all the requirements of life. In Malay, the coconut is known as pokok seribu guna, the tree of a thousand uses. In the Philippines, the coconut is generally given the title Tree of Life. The white, fleshy part of the seed is safe to eat and used fresh or dried in cooking.

Cloud

A cloud is a visible mass of condensed droplets, frozen crystals suspended in the atmosphere above the surface of the Earth or another earthly body, such as a moon. The branch of meteorology in which exhaust are studied is nephology.
On Earth the condensing matter is typically water vapor, which forms small droplets or ice crystals, typically 0.01 mm in diameter. When surrounded by billions of other droplets or crystals they become observable as clouds. Dense deep clouds exhibit a high reflectance throughout the visible range of wavelengths: they thus appear white, at least from the top. Cloud droplets tend to scatter light professionally, so that the intensity of the solar radiation decreases with depth into the cloud, hence the gray or even sometimes dark exterior of the clouds at their base. Thin clouds may appear to have acquired the color of their environment or background, and clouds illuminated by non-white light, such as through sunrise or sunset, may be colored accordingly. In the near-infrared range, clouds would appear darker because the water that constitutes the cloud droplets muscularly absorbs solar radiation at those wavelengths.
