Document Summary
A generalized cell three principal parts: 1. Plasma membrane forms the cells outer boundary; plays big role in cellular communication; selective barrier; separates exterior and interior: 2. Cytoplasm everything that is in between the cell membrane and the nucleus: 3. Nucleus large organelle that houses most of a cell"s dna. Membrane permeability: the cell is either permeable or impermeable to certain substances, permeable to oxygen, carbon dioxide, water, steroids, impermeable to glucose, etc. Transport across the plasma membrane: intracellular fluid (icf) fluid within the cell, extracellular fluid (ecf) fluid outside the cells, interstitial fluid fluid between tissue cells. Transport across the plasma membrane locations of various fluids: intracellular fluid (icf, extracellular fluid (ecf, interstitial fluid, plasma interstitial fluid of the blood vessels, lymph extracellular fluid in lymphatic vessels. Polyribosome 10 to 20 membrane bound ribosomes: endoplasmic reticulum, rough er studded with ribosomes; continuous with the nucleus via nuclear envelope. Page 41 three ways (blue balls w/ numbers .
