Section 1

Question Answer
NucleusSite of direction for cellular activities by means of DNA located here
RibosomesCytoplasmic sites of protein synthesis; may occur attached to ER or scattered freely in cytoplasm
Endoplasmic ReticulumSystem of membranous channels providing pathways for transport within the cell and surface areas for chemical reactions, may be granular (rough) or agranular (smooth)
Golgi ComplexStacks of cisternae with vesicular ends; involved in packaging, storing, and secretion of proteins and lipids
ChloroplastOrganelle mainly involved in photosynthesis
PeroxisomesSimilar to lysosomes, but smaller; contain the enzyme catalase that uses hydrogen peroxide to detoxify harmful chemicals in cells of the liver and kidneys

Section 2

Question Answer
MitochondriaCristae-containing structure, called "powerhouses of the cell" because ATP production occurs here
CiliaSmall, numerous hair-like structures which aid in m ovement of materials and cells
Plasma MembraneA phospholipid bilayer that controls the movement of substances into and out of the cell
MicrotubuleThick, hollow, cylinder-like filaments of the cytoskeleton that provide structural support and movement of chromosomes during mitosis
MicrofilamentsTiny rods of actin fibers used to provide flexible mechanical support for various cell
FlagellaLong, whip-like structure which provide motility to cells

Section 3

Question Answer
ChromoplastStores colored pigments which given appearance of fruits, flowers, and leaves
LysosomesVesicles that contain powerful enzymes that can digest bacteria, organelles, or entire cells by processes of phagocytosis, autophagy, or autolysis
CentriolesPart of cell's centrosome consisting of microtubles in a 9X3 arrangement which aids in cell division
VacuoleGeneral organelle that can store wastes, food, salts, and pigments
LeucoplastStorage organelle found in pants that contains starch
