The Chemical Basis for Life Vocabulary Worksheet
Student Name: ________________________________________ Date: ___________ Score: ______
Match the term on the left with its definition on the right:
__ Amino Acids
A. This holds an organisms hereditary information.
__ Carbohydrate
B. This is a macromolecule that holds cell information in a coded
form. Made of sugar, phosphate and nitrogen-containing bases.
__ DNA
C. This is a compound made up of carbon, hydrogen, and oxygen
atoms; it is used by cells to store and release energy. Sugars are
made by chloroplasts through photosynthesis and consumed by
mitochondria through cell respiration.
__ Lipid
D. A macromolecule that contains carbon, hydrogen, oxygen, and
nitrogen, which is used by the body for growth and repair.
__ Macromolecule E. This is a molecule that contains both amino and carboxylic acid
functional groups. They are the building blocks of protein.
__ Nitrogenous
Base
F. A single stranded nucleic acid that plays a role in protein synthesis.
__ Nucleic Acid
G. A macromolecule made up of mainly carbon and hydrogen atoms
that is primarily used for energy storage and in cell membranes.
__ Polymer
H. This is a molecule with a large molecular mass. Many examples
come from biology and in particular biochemistry.
__ Protein
I. This is a large, covalently-bonded molecule that has a repeated
structural unit.
__ RNA
J. This is the only part of a DNA/RNA nucleotide that changes. It is
found along with the 5-carbon sugar and the phosphate group.

Cells and Cellular Organization Vocabulary Worksheet
Match the term on the left with its definition on the right:
__ Cell Membrane A. This is a homogeneous, generally clear jelly-like material that fills
cells and serves as the broth of the cellular soup.
__ Cell Wall
B. These are singular, relatively long, whip-like organelles that many
unicellular organisms use for motion.
__ Centrioles
C. This organelle synthesizes proteins.
__ Chloroplast
D. This is any functional structure within the confines of a cell; literally
a. "small organ;" it usually has a membrane-based structure
__ Cilia
E. The structure that houses the cells genetic information.
__ Cytoplasm
F. These are organelles that digest macromolecules.
__ Cytoskeleton
G. These are short hair-like organelles on the surface of a eukaryotic cell
used for locomotion or sensory functions.
__ Flagella
H. An organelle found in most eukaryotic cells described as "cellular
power plants", because their primary function is to convert organic
materials into energy in the form of ATP
__ Golgi Body
I.
A thin, flexible, semipermeable barrier around the cell which
regulates what enters and leaves the cell.
__ Lysosome
J.
This is a plastid with chlorophyll in plants that photosynthesize.
__ Mitochondrion K. This structure provides support and protection for plant cells.
__ Nucleus
L. This is a scaffolding of protein fibers that help a cell keep its shape,
and assist cell division and cell movement.
__ Organelle
M. This is a tiny fluid-filled cavity in the cytoplasm. It can be used for
storage of biochemicals.
__ Pseudopodia
N. This is a shape-changing cell structure used by amoebas to move and
to engulf food.
__ Ribosome
O. These are barrel shaped microtubules in most animal cells, that
organize the spindles during cell division.
__ Vacuole
P. This organelle serves to process and package lipids and proteins in the
cell.
