BIL 150 - Mallery Practice Test with Actual Answers Latest
Update 2025
Microtubules tubulin proteins, long fibrillar and helical, "rods"
Centrosome pair of centrioles, organizes cilia, flagella, spindle fibers
Flagella microtubule extensions used for movement
Cilia microtubule hairlike tissues that act as oars
Basal body centriole found at the base of cilia and flagella
Dynein arms attach to microtubule doublets to induce movement
Kinesin motor protein powered by ATP; converts chemical energy to mechanical
Tight junction impermeabilize regions, prevent leakage
Desmosome adhering junction, cell adhesion
, Gap junction intercellular channels for communication
Plasmodesma cytoplasmic strands between plant cell walls
Vacoule mostly in plants; sac that plays role in digestion and waste; maintains turgor
pressure
Symplastic route internal, via plasmodesma
Apolplastic route external, via intercellular space
2 components of fluid mosaic model lipids and proteins
Solute movement across membrane based on lipid solubility
Hypertonic Solution high solute, low water
Hypotonic Solution low solute, high water
Isotonic Solution equal solute-water
