Update ) Genetics | Questions
& Answers | Grade A | 100% Correct -
Portage Learning
cell -CORRECTANSWER The basic unit of structure and function in living things
cell theory -CORRECTANSWER idea that all living things are composed of cells, cells
are the basic units of structure and function in living things, and new cells are produced
from existing cells
plasma membrane (cell membrane) -CORRECTANSWER Regulates what enters and
leaves the cell and separates the internal environment of the cell from the external
environment
Nucleus -CORRECTANSWER A membrane bound organelle inside eukaryotic cells
containing DNA and RNA and responsible for growth and reproduction
Organelle -CORRECTANSWER specialized structure that performs important cellular
functions within a eukaryotic cell
microscopes -CORRECTANSWER devices that produce magnified images of
structures that are too small to see with the unaided eye
, phospholipid bilayer -CORRECTANSWER Plasma membrane layers composed of
phospholipid molecules arranged with polar heads facing the outside and nonpolar tails
facing the inside.
transport protein -CORRECTANSWER A transmembrane protein that helps a certain
substance or class of closely related substances to cross the membrane.
fluid mosaic model -CORRECTANSWER The currently accepted model of cell
membrane structure, which envisions the membrane as a mosaic of individually inserted
protein molecules drifting laterally in a fluid bilayer of phospholipids.
selective permeability -CORRECTANSWER A property of biological membranes that
allows some substances to cross more easily than others.
Diffusion -CORRECTANSWER Movement of molecules from an area of higher
concentration to an area of lower concentration.
dynamic equilibrium -CORRECTANSWER condition of continuous, random movement
of particles but no overall change in concentration of materials
facilitated diffusion -CORRECTANSWER process of diffusion in which molecules pass
across the membrane through cell membrane channels
