OpenStax Biology 2e Chapter 4 Cell Structure Exam
Questions with Answers Correctly Solved to Score A+
cell wall - Answer rigid cell covering comprised of various molecules that protects the cell, provides
structural support, and gives shape to the cell
central vacuole - Answer large plant cell organelle that regulates the cell's storage compartment, holds
water, and plays a significant role in cell growth as the site of macromolecule degradation
centrosome - Answer region in animal cells made of two centrioles that serves as an organizing center
for microtubules
chlorophyll - Answer green pigment that captures the light energy that drives the light reactions of
photosynthesis
chloroplast - Answer plant cell organelle that carries out photosynthesis
chromatin - Answer protein-DNA complex that serves as the chromosomes' building material
chromosome - Answer structure within the nucleus that comprises chromatin that contains DNA, the
hereditary material
cilium (plural = cilia) - Answer short, hair-like structure that extends from the plasma membrane in large
numbers and functions to move an entire cell or move substances along the cell's outer surface
cytoplasm - Answer entire region between the plasma membrane and the nuclear envelope, consisting
of organelles suspended in the gel-like cytosol, the cytoskeleton, and various chemicals
cytoskeleton - Answer protein fiber network that collectively maintains the cell's shape, secures some
organelles in specific positions, allows cytoplasm and vesicles to move within the cell, and enables
unicellular organisms to move independently
