Working in groups of two to four and armed with the definitions just provided in lecture a
textbook, or another reliable source answer the following questions about the cell (Chapter 4). This
assignment is worth 30 points with the possible points for each question in parenthesis.
1. (10) Draw and label a diagram of the arrangement of the molecules found in a plasma
membrane.
2. (10) Label (or draw onto) the cell figure with the following cellular terms:
Membrane Bound Organelles: Nucleus, Nuclear Envelope, Nuclear Pore, Nucleolus,
Chromatin, Endoplasmic Reticulum (rough & smooth), Golgi apparatus, Lysosome, Peroxisome,
Mitochondria, Chloroplast, and Vacuoles (those found in either animal or plant cells).
Non-membrane Bound Organelles: Cytoskeletal elements (microfilaments, intermediate
filaments, & microtubules), Centrioles, free ribosome.
Cellular Extensions: Microvilli, Cilia, and Flagella
3. (10) Fill-in the table to show the function(s) of each labeled part and any uniqueness of the
organelles structure.
