1. A - SMOOTH ER: Site of synthesis of
lipid and steroid molecules
B- MITOCHONDRIA: Produces ATP aer-
obically
C - LYSOSOMES: Site of enzymatic
breakdown of phagocytized material
AND Source of cell autolysis.
D- MICROTUBULES: Forms the mitotic
spindle AND Replicate for cell division
E - GOLGI APPARATUS: Packages pro-
teins for insertion in the cell mem-
brane or for exocytosis
2. Plasma membrane A selectively-permeable phospholipid bilayer form-
ing the boundary of the cells
3. cystoplasm cellular material between the plasma membrane
and the nucleus
consists of the cytosol and organelles
4. nucleus Control center of the cell, houses DNA
5. Endoplasmic Reticulum a network of tubular membranes within the cyto-
plasm of the cell, occurring either with a smooth
surface (smooth endoplasmic reticulum) or stud-
ded with ribosomes (rough endoplasmic reticu-
lum) involved in the transport of materials.
6. A - Glycocalyx AND Identification
"tags" for the cell
B - Polar regionof phospholipid AND
Hydrophilic portion of phospholipid
C - Nonpolar region of phospholipid

D - Integral protein.
E - Peripheral protein
7. Transfer RNA Act as "interpreter" molecules that recognize spe-
cific amino acids and nucleotide base sequences
8. Synthetase enzymes Attaches the correct amino acid to its transfer RNA
9. Ribosimal RNA Forms part of the protein synthesis site in the cyto-
plasm
AND
May be attached to the ER or scattered in the cyto-
plasm
10. ATP Provides the energy needed for synthesis reactions
11. Messenger RNA Produced in the nucleus, this molecule specifies the
exact sequence of amino acids of the protein to be
made
12. Early prophase Centrioles move to opposite ends of the cell.
13. Late prophase Nuclear membrane and nucleolus disintegrate
14. Anaphase Chromosomal centromeres split and chromosomes
migrate apart to opposite ends of the cell
15. Metaphase Chromosomes align on the spindle equator in the
middle
16. Telophase Chromosomes uncoil to form chromatin
17. Nucleus Houses DNA and RNA
18. Microtubules
