Chapter 5, Problem 11TYU
Summary Introduction
To connect: The account for the difference between the adjacent plant cells that are connected by plasmodesmata with the adjacent animal cells that are connected through gap junctions.
Concept introduction: Cell junctions are multiprotein structures that link the cells to each other and to the environment. They help in cell-cell communication and signal transduction in multicellular organisms such as animals and plants. The examples for cell junctions in animal cells are anchoring junctions, tight junctions, and gap junctions, whereas plant cells are connected by plasmodesmata.

MAIN IDEA: Eukaryotic cells have an extensive and dynamic framework called a cyto-
skeleton. The cytoskeleton is used for cell shape, internal structure, movement, and cell
division. Many cells are surrounded by and supported by a complex extracellular matrix and
are able to interact with adjacent cells and the environment via cell junctions.
5. List three common components of microtubules and microfilaments.
