and their Functions
1.
You begin your journey at an organelle that stores genetic information (also
known as DNA), and contains
chromatin, histone, and chromosomes. What organelle is this?

At the next stop in your journey, you are in a structure that surrounds the
nucleus. It blocks DNA from
leaving and allows RNA to leave, and contains embedded proteins called
nuclear pores. Where are you?

At the next organelle, you cannot see any ribosomes. However, lipids,
membranes, and hormones are manufactured here. Also, this part of the cell is
responsible for detoxifying drugs and poisons. What is this structure called?

Typically, the next organelle is found more than once in a cell. They are
used to increase surface area. For example, cells in the intestinal track have
these so they are more efficient at absorbing nutrients. What part of the cell
is this?

You are now at the organelle that provides structural support and holds
organelles in place. It is comprised of three types of protein fibers:
microtubules, microfilaments, and intermediate filaments. What is this
structure called?
