Campbell Biology In Focus Chapter 4
Basal Body - ANSWER A cellular organelle associated with the formation of cilia and flagella
and similar to the centriole in structure.
Cell Fractionation - ANSWER Technique in which cells are broken into pieces and the
different cell parts are separated
Cell Wall - ANSWER A rigid structure found in pland cells that surrounds the cell membrane
and provides support to the cell
Central Vacuole - ANSWER A membranous sac in a mature plant cell with diverse roles in
reproduction, growth, and development.
Centrioles - ANSWER Cylinder structures that are composed of 9 sets of triplet
microtubules
Centrosome - ANSWER A structure present in the cytoplasm of animal cells that functions
as a microtubule-organizing center and is important during cell division. A centrosome has two
centrioles.
Chloroplasts - ANSWER A structure in the cells of plants and some other organisms that
captures energy from sunlight and uses it to produce food.
Chromatin - ANSWER DNA and protein that makes up chromosomes
Chromosomes - ANSWER DNA Structures that carry genetic information
Cilla - ANSWER The hairlike projections on the outside of cells that move in a wavelike
manner
Collagen - ANSWER A fibrous protein found in connective tissue
Cristae - ANSWER An infolding of the inner membrane of a mitochondrion that houses the
electron transport chain and the enzyme catalyzing the synthesis of ATP.
Cytoplasm - ANSWER A jellylike fluid inside the cell in which the organelles are suspended
Cytoskeleton - ANSWER A network of long protein strands in the cytosol that helps support
the cell
Dyneins - ANSWER Attached along each outer microtubule doublet and they use ATP for
energy
Electron Microscope - ANSWER Microscope that forms an image by focusing beams of
electrons onto a specimen.
Endomembrane System - ANSWER A network of membranes that includes the nuclear
envelope, ER, golgi apparatus, lysosomes, various vesicles and vacuoles, and the plasma membrane.
Endoplasmic Reticulum - ANSWER forms a maze of passageways in which proteins and
other materials are carried form one part of the cell to another
