1.
This membrane is a selectively permeable boundary that separates the cell from its environment.
2.
Molecule with a hydrophilic head and hydrophobic tails that forms the basic structure of cell membranes.
3.
Model describing the membrane as a dynamic phospholipid bilayer containing mobile proteins and lipids.
4.
Membrane molecule that helps regulate membrane fluidity across different temperatures.
5.
Protein embedded in or spanning the membrane; can function in transport, signaling, or as an enzyme.
6.
Protein loosely attached to the membrane that can assist with signaling or cytoskeletal attachment.
7.
Membrane protein with attached carbohydrates involved in cell recognition and adhesion.
8.
Membrane lipid with attached carbohydrates involved in cell recognition and identification.
9.
Hollow fibers made of tubulin that help with intracellular transport, cilia, flagella, and chromosome movement during cell division.
10.
Thin actin fibers involved in cell movement, muscle contraction, and cytokinesis.
11.
Protein that makes up microfilaments and helps cells move and change shape.
12.
These filaments are rope-like cytoskeletal fibers that provide structural support and tensile strength.
13.
Proteins that use energy to move along cytoskeletal fibers and transport materials within cells.
14.
Motor protein that generally moves toward the plus end of microtubules.
15.
Motor protein that generally moves toward the minus end of microtubules.
16.
Motor protein that moves along actin filaments and is important in muscle contraction and cell movement.
17.
Network of protein fibers that gives the cell shape, support, organization, and movement.
18.
This matrix is material outside animal cells that provides support, adhesion, and signaling; contains substances such as collagen and fibronectin.
19.
This junction is a connection between neighboring cells that prevents substances from leaking between them.
20.
Cell junction that anchors neighboring cells together and helps them resist mechanical stress.
21.
This junction is a channel connecting neighboring animal cells that allows direct communication between them.
22.
Channels connecting the cytoplasm of neighboring plant cells.
