BSC 1005 Chapter 4 questions with verified answers
Adhering Junction Ans✓✓✓ Cell Junction composed of adhesion
proteins that connect to cytoskeletal elements. Fastens cells to each
other and basement membrane
Adhesion Protein Ans✓✓✓ Protein that helps cells stick together in
animal tissues
Basal Body Ans✓✓✓ Organelle that develops from a centriole
Biofilm Ans✓✓✓ Community of microorganisms living within a shared
mass of secreted slime
Cell Cortex Ans✓✓✓ Mesh of cytoskeletal elements under a plasma
membrane
Cell Junction Ans✓✓✓ Structure that connects a cell to another cell or
to extracellular matrix
Cell Theory Ans✓✓✓ Theory that all organisms consist of one or more
cells, which are the basic unit of life; all cells come from division or
preexisting cells; and all cells pass hereditary material to offspring
, Cell Wall Ans✓✓✓ Rigid but permeable structure that surrounds the
plasma membrane of some cells
Central Vacuole Ans✓✓✓ Fluid filled vesicle in many plant cells
Centriole Ans✓✓✓ Barrel-shaped organelle from which microtubules
grow
Cilium Ans✓✓✓ Short, movable structure that projects from the
plasma membrane of some eukaryotic cells
Cuticle Ans✓✓✓ Secreted covering at a body surface
Cytoplasm Ans✓✓✓ Semi-fluid substance enclosed by a cell's plasma
membrane
Cytoskeleton Ans✓✓✓ Network of interconnected protein filaments
that support, organize, and move eukaryotic cells and their parts
Endomembrane System Ans✓✓✓ Series of interacting organelles
between nucleus and plasma membrne; produces lipids, proteins.
Endoplasmic Reticulum Ans✓✓✓ Organelle that is a continuous system
of sacs and tubes extending from the nuclear envelope. Smooth ER
