Graded A+ 2025-2026 Edition.
Cell Wall - Answer A rigid structure that surrounds the cells of plants, fungi, many protists,
and most bacteria
Chloroplast - Answer A plastid containing chlorophyll; the site of photosynthesis
Chromatin - Answer The DNA and proteins in a non-dividing cell
Chromosome - Answer DNA and protein in a coiled, rod-shaped form that occurs during cell
division
Cilium (cilia) - Answer A short, hairlike organelle that extends from a cell and functions in
locomotion
Cytoplasm - Answer The region of a cell between the cell membrane and the nucleus
Cytoskeleton - Answer A network of long protein strands in the cytosolthat helps maintain
the size and shape of the eukaryotic cell
Cytosol (cytoplasm) - Answer The gelatin like aqueous fluid that bathes the organelles on the
inside of the cell membrane
Endoplasmic Reticulum - Answer A system of membranous tubes and sacs in eukaroyotic
cells that functions as a path along which molecules move from one part of the cell to the other
Flagellum (flagella) - Answer A hair-like structure made up of microtubles that function in
locomotion
Fluid Mosaic Model - Answer A model of cell membranes structure representing the
dynamic nature of membrane lipids and proteins
, Lysosome - Answer A organelle containing digestive enzymes, existing primarily in animal
cells
Microtubule - Answer A hollow tube of protein that constitutes the largest strand in the
cytoskelton

Nuclear Envelope - Answer A double membrane that surrounds the nucleus of eukaryotic
cells
Nuclear Pore - Answer A small hole in the nuclear envelope through which substances pass
between the nucleus and the cytoplasm
Ribosome - Answer An organelle that funtions in the synthesis of proteins
Rough Endoplasmic Reticulum - Answer The portion of the endoplasmic reticulum that
contains attached ribosomes
Selectively Permeable Membrane - Answer A membrane that keeps some molecules out but
allows others to pass through
Smooth Endoplasmic Reticulum - Answer The portion of the endoplasmic reticulum that
lacks attached ribosomes
Spindle Fiber - Answer One of the microtubles that extend across a dividing eukaryotic cell;
assists in the movement of chromosomes
Vacuole - Answer A fluid filled organelle that store enzymes of metabolic waste material
Concentration Gradient - Answer the difference of a concentration of substance across a
space
