Question

name the seeds that float on water

Answer 1

some seed float on water as insects or pest have eaten it so they become light in weight and hence float.

Well, there can be two reasons for seeds floating on water:

(1) The seed may have a density which is less than that of water and thus it floats.

(2) The seed may be having a waxy coating on its surface which helps it to float.
