Sunflower seeds were collected from the field and hulls of seed were taken out for observation under foldscope.

 The house fly, Musca domestica Linnaeus, is a well-known cosmopolitan pest of both farm and home. This species is always found in association with humans or the activities of humans. The labella are two separate organs, attached to the proboscis only at their bases, but in the flies with short antennae, such as the house fly, they are more or less fused to form a single structure.

 We observed rice seed under foldscope and found only 2 number of trichomes on it.

 After observing this rice seed under foldscope, we found many number of trichomes on seed comapared to previous rice seed. So there will be differences between rice genotypes based on seed trichomes observed under foldscope

 These are the pictures of the rice seeds. I observed small part of rice seed hull for its trichomes through foldscope.
