CELL ORGANELLE "SCRAMBLE"
Cell Structure
1.
Description / Location
Function
External boundary of the cell
Confines cell contents; regulates entry and
exit of materials.
3.
Scattered throughout the cell
4.
Projections of the plasma membrane
at the cell's apical surface.
Controls release of energy from foods; location where most ATP formation takes place.
Increase the plasmalemma's surface area
2. Lysosomes
5. Golgi Body
(aka: Golgi Apparatus)
6.
A dense mass surrounding two barrelshaped bodies (centrioles) adjacent to
the nucleus
The centrioles "spin" the mitotic (or meiotic)
spindle apparatus.
7. Smooth ER
8. Rough ER
9.
Attached to plasmalemma or scattered
in the cytoplasm.
Workbenches upon which proteins are
synthesized.
10. Cilia
11.
Internal structure of microvilli; part of
the cytoskeleton
12. Peroxisomes
13.
14.
15. Cytoskeleton
(a) Microfilaments
(b) Intermediate filaments
(c) Microtubules
16.
Usually in the very center of the cell.
Storehouse for genetic information; directs
Cellular activities including protein synthesis
And cell division.
Storehouse for RNA-nucleotides and DNAnucleotides; assembly site for ribosomes.
This is the form DNA takes in the non-dividing cell.
