ANATOMY AND PHYSIOLOGY 7TH
EDITION ELAINE N MARIEB ACTUAL PAPER
SOLVED QUESTIONS
◉ Tissues
Answer: Groups of cells that are similar in structure and function
◉ Nucleus
Answer: Control center of cell, contains DNA, necessary for cell
reproduction.
◉ Nuclear Envelope
Answer: Encloses the jelly-like fluid nucleoplasm in which other
nuclear elements are suspended
◉ Nucleoli
Answer: One or more may be present in the nucleus, site of
ribosome assembly
◉ Chromatin
Answer: When a cell is not dividing, its DNA is combined with
protein and forms a loose network of bumpy threads called
_________.
,◉ Chromosomes
Answer: When a cell is dividing to form two daughter cells, the
chromatin threads coil and condense to form dense, rod-like
bodies called ___________.
◉ Plasma Membrane
Answer: A fragile, transparent barrier that contains the cell
contents and separates them from the surrounding environment.
◉ Hydrophobic
Answer: The __________ makeup of the membrane interior makes
the plasma membrane relatively impermeable to most water-
soluble molecules.
◉ Tight Junctions
Answer: Impermeable, bind cells together into leak-proof sheets
◉ Desmosomes
Answer: Anchoring junctions that prevent cells from being pulled
apart
◉ Gap junctions
Answer: Allow communication between cells
,◉ Cytoplasm
Answer: The cellular material outside the nucleus, inside the
plasma membrane. The "factory area" of the cell.
◉ Cytosol
Answer: Semi-transparent fluid that suspends other elements
◉ Organelles
Answer: Metabolic machinery of the cell
◉ Mitochondria
Answer: The "powerhouse" organelles that convert the chemical
energy stored in food into compounds that are more convenient
for the cell to use
◉ Ribosomes
Answer: Site of protein synthesis found in two locations: free in
cytoplasm, as part of rough ER
◉ ER: Endoplasmic Reticulum
Answer: Fluid filled tubules for carrying substances
◉ Golgi Apparatus
Answer: Modifies and packages proteins ("Traffic Director"),
produces different types of packages
, ◉ Lysosomes
Answer: Contain enzymes that digest worn out or non-usable
materials within the cell
◉ Cytoskeleton
Answer: Network of protein structures that extend throughout the
cytoplasm
◉ Microfilaments
Answer: Fine, threadlike proteins found in the cell's cytoskeleton
◉ Intermediate filaments
Answer: Rope-like strands of protein that help to form
desmosomes and resist pulling forces on the cell, located in the
cell's cytoskeleton
◉ Centrioles
Answer: Rod shaped bodies made of a pinwheel array of fine
microtubules, lie at right-angles to each other and direct the
formation of mitotic spindle during cell division
◉ Cilia
Answer: Move materials across the cell surface (located in the
respiratory system to move mucus)
