I haven't been able to identify this sample. I have reason to believe it may be part of a plant stem. Ants have hair on their body and eyes that is called setae. These hairs allow the insect to detect air currents, feel textured surfaces and to smell. Their compound eyes aren't usually red like Drosophila's .
Pollen is the gametophyte generation of seed plants.
Each pollen grain contains two sperm nucleii and one tube nucleus. The texture of pollen is so unique that it is actually used to classify plants. Vein development actually occurs on the dorsal and ventral surfaces of the wing disc independently. These human sperm are shown as clumped in semen. Tetrahymena are single celled, cilliated protazoa.
