Cells become specialized through the process of - ✔✔differentiation or maturation
Eight specialized cellular functions are - ✔✔movement, conductivity, metabolic
absorption, secretion, excretion, respiration, reproduction, and communication
Eukaryotic cells consist of - ✔✔the plasma membrane, the cytoplasm, and intracellular
organelles
What is the nucleus? - ✔✔the largest membrane-bound organelle and found in the cell's
center
Chief functions of the nucleus are? - ✔✔cell division and control of genetic information
What is cytoplasm (cytoplasmic matrix)? - ✔✔an aqueous solution (cytosol) that fills the
space between the nucleus and the plasma membrane
Where are organelles found? - ✔✔suspended in the cytoplasm and enclosed in biologic
membranes
What is the endoplasmic reticulum? - ✔✔a network of tubular channels (cisternae) that
extend throughout the outer nuclear membrane. It specializes in the synthesis and
transport of protein lipid components of most of the organelles
What is the Golgi complex? - ✔✔a network of smooth membranes and vesicles located
near the nucleus
What does the Golgi complex do? - ✔✔process and package proteins into secretory
vesicles that break away from the Golgi complex and migrate to a variety of intracellular
and extracellular destinations, including plasma membranes
What are lysosomes? - ✔✔sac-like structures that originate from the Golgi complex and
contain digestive enzymes.
What do lysosomal enzymes do? - ✔✔responsible for digesting most cellular
substances to their basic form, such as amino acids, fatty acids, and carbohydrates
(sugars)
What does cellular injury lead to? - ✔✔a release of the lysosomal enzymes, causing
cellular self-digestion
