What structures in single-celled organisms act like organs & organ systems? HELP

cell organelles

Explanation:

Organelles are like the "organs" of a cell; they are small structures that perform different functions that help cells survive.

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
