The cells in our body are actually quite similar to unicellular, organisms, like the one seen here. feeding, removing waste, reproducing: all actions they both have in common. what else do we have in common with this unicellular organism?

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you

digestion

it excretes wastes
