PRACTICE SOLUTIONS GRADED A+
● The eight specialized cellular functions are. Answer: movement,
conductivity, metabolic absorption, secretion, excretion, respiration,
reproduction, communication
● Eukaryotic cells. Answer: Contain a nucleus and other organelles that
are bound by membranes.
● The eukaryotic cell consists of three general components. Answer:
plasma membrane, cytoplasm, and intracellular organelles
● Nucleus. Answer: A part of the cell containing DNA and RNA and
responsible for growth and reproduction
● Vaults. Answer: cytoplasmic organelles that are carrying messengers
of ribonucleic acid (mRNA) from the nucleus to the ribosomal sites of
protein synthesis
● plasma membrane (cell membrane). Answer: It's function is to protect
the cell and control what goes in and out. It is not a solid structure. It is
made of millions of smaller molecules so it is flexible and porous
(allows things to pass through it).
, ● cellular receptors. Answer: protein molecules on the plasma
membrane, in the cytoplasm, or in the nucleus that can recognize and
bind with specific smaller molecules called ligands
● Ligands. Answer: A molecule that binds specifically to a receptor site
of another molecule.
● Cells are held together by three different means:. Answer: (1) the
extracellular membrane, (2) cell adhesion molecules in the cell's plasma
membrane, and (3) specialized cell junctions.
● Cells communicate in three main ways. Answer: (1) they form protein
channels (gap junctions); (2)
they display receptors that affect intracellular processes or other cells in
direct physical
contact; and (3) they use receptor proteins inside the target cell.
● reception. Answer: The target cell's detection of a signal molecule
coming from outside the cell.
● Transduction. Answer: conversion of one form of energy into another
