 The
cytoplasm is the semi-fluid material
that contains the organelles
 The
cell membrane is the thin flexible
barrier surrounding a cell
• Lipid bilayer
• Regulates what enters and leaves the cell
 Selectively permeable membrane
• Protects and supports the cell
 The
nucleus contains the chromosomes
which are composed of DNA (deoxyribonucleic
acid, a chemical compound that stores and transmits genetic
information) and
functions as the genetic
control center of the cell
A
chromosome is a structure in the
nucleus of a cell consisting essentially of
one long thread of DNA that is tightly
coiled.
 The
cytoskeleton is a network of fibrous
proteins that helps the cell with
maintaining shape, support, and
movement.
 Endoplasmic
reticulum (ER) is a complex,
extensive network that transports
materials throughout the inside of a cell.
• Rough ER has ribosomes
attached to the surface.
• Smooth ER
has no
ribosomes
 Ribosomes
are the sites of protein
synthesis; some are located on the ER,
others are found in the cytoplasm.
 The
Golgi complex/ apparatus modifies,
collects, packages, and distributes
proteins and other materials to be used
within or outside the cell.
 Lysosomes
break down lipids,
carbohydrates, and proteins into small
molecules that can be used by the cell.
 Vacuoles
store materials like water, salts,
proteins, and carbohydrates.
 Vesicles
are smaller structures that store
and move materials between cell
organelles, as well as to and from the cell
surface.
 Mitochondria
supply the energy for the
cell
• Converts chemical energy stored in food into
usable energy for the cell
 Group
deliverables: on poster paper
• Create a chart that matches the part of a factory
to an organelle (this is an analogy!)
 Use the handout BEFORE you draw on your poster
• Labeled and colored cell drawing from handout
• Flowchart (question 9)
 See Figure 7.11 on Pages 200-201 of your textbook
 Individual
deliverables: on handout
• Questions 1-18
• Each person must submit
 Cellular
processes are carried out by
molecules. Proteins carry out most of the
work of cells to perform the essential
functions of life. One of the major functions
of the cell is the production of proteins. The
genetic information in DNA provides
instructions for assembling protein
molecules. In eukaryotic cells the nucleus,
ribosomes, endoplasmic reticulum, vesicles,
and the Golgi apparatus interact to produce,
modify and transport proteins.
