Given, Speed=0.06m/s =0.06×3600/1000km/h =0.216km/h

As velocity is constant, so it travels equal distance in equal interval of time. Hence, object is in uniform motion.

In case of linear or straight-line motion, the displacement of the object is equal to the distance covered.

Leucoplast is a colourless plastid which stores proteins, lipids and starch, while xanthophyll are yellow, read or Orange pigments of green plants.

The spontaneous movement of a substance from a region of high concentration to a region where its concentration is low is done by the process of diffusion.
