THE CONNECTION BETWEEN STRUCTURE AND FUNCTION
1. A STUDY OF THE CELL AND OF PROTOZOA
_To show what Single Cells can Do_
_Materials._
Some single cells of plant or animal tissue, stained to show structure. Slides of a one-celled animal, stained. Living one-celled animals.
_Definitions._
_Cell_, the smallest living unit.
_Protoplasm_, the living material composing the cell.
_Nucleus_, a dense bit of protoplasm, usually near the center of the cell, often staining dark.
_Cytoplasm_, the less dense protoplasm outside of the nucleus, usually taking a lighter stain.
_Nucleolus_, _paranucleus_ or _micronucleus_, a very small, dense, dark-staining body, either within the nucleus (nucleolus) or near it (paranucleus or micronucleus)
_Cell wall_, the lifeless membrane surrounding many cells, secreted by the protoplasm.
