STRUCTURE & FUNCTION OF THE BODY ED 16
EXAM QUESTIONS WITH 100% VERIFIED
SOLUTIONS
cytoplasm - ANS-the material or protoplasm within a living cell, excluding the nucleus; the living
substance that exists only in cells; all the living material inside the cell (except the nucleus); fills the
spaces between the plasma membrane and the nucleus
plasma membrane - ANS-thin membrane that surrounds each cell in the body; separates the cells
contents from interstitial fluid; forms the cells outer boundary; phospholipid bilayer studded with
proteins; protein and carbohydrate molecules on the outer surface serve as markers that identify cells of
each individual, as receptor molecules for certain hormones, or transporters to move substances
through the membrane
interstitial fluid (IF) - ANS-tissue fluid, which bathes every cell in the body
organelles - ANS-specialized structures contained within the cytoplasm of each cell; little organs;
function for the cell as organs function for the body
nucleus - ANS-small, circular body inside the cell; large, membrane- bound structure in most cells that
contains most of the cell's genetic code; double-membraned, spherical envelop containing DNA strands;
contains DNA, which dictates protein synthesis, thereby playing an essential role in other cell activities
such as transport, metabolism, growth, and heredity; controls every organelle in the cytoplasm and cell
reproduction
three main parts of a cell - ANS-plasma membrane, cytoplasm, nucleus
phospholipids - ANS-phosphate-containing lipid molecules that form a fluid framework for the plasma
membrane; stabilized by cholesterol to prevent breakage of the plasma membrane
cytoskeleton - ANS-cell skeleton; small threadlike structures in cytoplasm that interconnect; organizes
and supports organelles; contain microfilaments and microtubules
microfilaments - ANS-Fine, threadlike proteins found in the cell's cytoskeleton
microtubules - ANS-A hollow rod composed of tubulin proteins that makes up part of the cytoskeleton in
all eukaryotic cells and is found in cilia and flagella.
