Question

which of the following are boundary structures for a eukaryotic cell? more than one answer may be correct. glycocalyx intermediate filaments flagella cilia cell wall cytoplasmic membrane

Explanation:

The cytoplasmic membrane (plasma membrane) and cell wall are boundary - defining structures for eukaryotic cells. The cytoplasmic membrane is the innermost boundary that separates the cell's interior from the external environment. Some eukaryotic cells, like plant cells, also have a cell wall outside the plasma membrane which provides additional support and protection. Cilia and flagella are appendages for movement, intermediate filaments are part of the cytoskeleton for structural support, and the glycocalyx is a carbohydrate - rich layer on the cell surface mainly involved in cell - cell recognition and adhesion, not primary boundary structures.

Answer:

cytoplasmic membrane, cell wall
