IBIO 425 Study Guide - Final Guide: Cell Potency, Hyperplasia, Necrosis
Document Summary
Increased cell number hypertrophy increase cell size/volume apoptosis programmed cell death internally initiated. Non-inflammatory end of differentiation process necrosis unplanned cell death. Not fully differentiated cells (not completely specialized yet). Can proliferate (multiply) mitotically, and the daughter cells have the potential to differentiate further, often into multiple (multipotent, pluripotent) different kinds of progenitor and mature cells. Multipotent- having the potential of becoming any of several mature cell types. Pluripotent- capable of giving rise to several different cell types. Embryonic cells are totipotent (capable of developing into a complete organism or differentiating into any of its cells or tissues) Groups of two or more tissues combined to form complex functional units. Combinations of several discrete organs whose functions are interrelated. Segregated from the aqueous cytoplasmic compartment by selectively permeable membranes of phospholipids and proteins. Responsible for division of biochemical labor within the cell by specific entities. Includes: nucleus, mitochondria, er, golgi, endosomes, vesicles, lysosomes, peroxisomes.
