Cell Biology Exam Questions and Answers
cell theory - -All living things are composed of cells. Cells are the basic units of structure
and function in living things. New cells are produced from existing cells.
-prokaryotes - -Cells that have genetic material that is NOT contained in a nucleus
-eukaryotes - -Cells that contain a nucleus in which their genetic material is separated
from the rest of the cell.
-organelles - -The structures inside the cell that act as specialized organs
-nuclear envelope - -surrounds the nucleus and controls what goes in and out of the
nucleus through the nuclear pores
-chromatin - -DNA bound to protein and contained in the nucleus of the cell
-ribosomes - -The organelle in the eukaryotic cell that is responsible for protein synthesis
(manufacture).
-Endoplasmic Reticulum - -The organelle in a eukaryotic cell where lipid components of
the cell membrane are assembled, along with proteins and other materials that are
exported from the cell. Equate to the assembly line in a manufacturing center
-nucleus - -The cell organelle that contains the cells DNA. The DNA in the nucleus contains
the coded instructions for making proteins and other important molecules. The nucleus is
the 'brain' of the cell.
-Endoplasmic Reticulum - -The organelle in a eukaryotic cell where lipid components of
the cell membrane are assembled, along with proteins and other materials that are
exported from the cell. Equate to the assembly line in a manufacturing center
-nucleus - -The cell organelle that contains the cells DNA. The DNA in the nucleus contains
the coded instructions for making proteins and other important molecules. The nucleus is
the 'brain' of the cell.
-Golgi apparatus - -This organelle modifies, sorts, and packages proteins and other
materials as they come off the endoplasmic erticulum for storage in the cell or secretion
outside the cell. The packaging and shipping center. Like FedEx!
-Lysosomes - -Cell organelles filled with enzymes for the digestion or breakdown or lipids,
carbohydrates, and proteins into small molecules that can be used by the rest of the cell.
-Cell Membrane - -Thin flexible barrier aroun a cell that regulates what enters and leaves
the cell.
