ATP - Answer(adenosine triphosphate) main energy source that cells use for most of
their work
Cancer - Answerany malignant growth or tumor caused by abnormal and uncontrolled
cell division
Cell - Answer(biology) the basic structural and functional unit of all organisms
Cell theory - Answer(biology) the theory that cells form the fundamental structural and
functional units of all living organisms
Cell wall - Answera thin membrane around the cytoplasm of a cell
Chloroplast - Answeran organelle found in plant and algae cells where photosynthesis
occurs
Cilia - AnswerThe hairlike projections on the outside of cells that move in a wavelike
manner
Cytoplasm - Answera jellylike fluid inside the cell in which the organelles are
suspended
Cytoskeleton - Answernetwork of proteins in the cytoplasm that help cell maintain its
shape
Cytosol - Answerthe semifluid portion of the cytoplasm
DNA - Answerdeoxyribonucleic acid, the material that contains the information that
determines inherited characteristics
Electron microscope - Answerinstrument that uses a beam of electrons instead of light
to magnify structures up to 500,000 times actual size; allows scientists to view
structures within a cell
Endomembrane system - AnswerThe collection of membranes inside and around a
eukaryotic cell
, Endoplasmic reticulum - Answerinternal transport system of the cell, modifies
proteins, and synthesizes lipids
Eukaryote - AnswerA cell that contains a nucleus and membrane bound organelles
Extracellular matrix - AnswerThe substance in which animal tissue cells are
embedded, consisting of protein and polysaccharides.
Flagella - Answerwhiplike tails found in one-celled organisms to aid in movement
Golgi apparatus - Answerstack of membranes in the cell that modifies, sorts, and
packages proteins from the endoplasmic reticulum
Light microscope - Answermicroscope that uses a beam of light passing through one
or more lenses to magnify an object
Lysosome - Answercell organelle filled with enzymes needed to break down certain
materials in the cell
Microfilament - Answersolid rod of protein, thinner than a microtubule, that enables a
cell to move or change shape
Microtubule - Answerthin, hollow cylinders made of protein that provide structural
support for eukaryotic cells
Mitochondria - Answerthe organelles in which nutrients are converted to energy
Nucleolus - AnswerThe organelle where ribosomes are made, synthesized and
partially assembled, located in the nucleus
Peroxisome - Answera microbody containing enzymes that transfer hydrogen from
various substrates to oxygen, producing and then degrading hydrogen peroxide
Pili - Answershort, hairlike protein structures on the surface of some bacteria
Plant cell wall - AnswerMade out of cellulose/ Provides support and protection for the
cell
Prokaryote - AnswerA unicellular organism that lacks a nucleus and membrane bound
organelles
Ribosome - AnswerAn organelle that functions in the synthesis of proteins
