Some cells have the ability to move. It is designed to turn food (usually sugar) into a form that enables it to move. What organelle does a cell need an abundance of in order to move?

Cacti typically have spines instead of leaves. The stem of a cactus is green, which indicates that it contains a chemical that is stored in a particular organelle. What is the name of the chemical in the stem of a cacti? What organelle is the chemical stored in?

An interesting phenomenon occurs in plants that are withering: when watered they "perk up" or stand up. This is evidence of a plant needing water. What organelle in a plant do you think is most associated with this phenomenon?

White blood cells are especially active when you are sick, because bacteria or viruses that do not belong in you are present in your body. White blood cells work with a particular organelle to break down bacteria or viruses to help you feel better. What organelle do you think is plentiful in white blood cells?

Red blood cells (RBCs) are missing an organelle that provides the instructions to reproduce and is found in most other cells. As a result, RBCs do not reproduce themselves, but instead, are made in bone marrow and live a very short time. What organelle is missing from RBCs?

Your skin is a protective covering that acts as a barrier to keep you safe on the inside and outside. When you get a cut, you begin to bleed because your skin actually has an opening in it. What part of your skin cells is punctured when you have a cut?

Endocrine cells make hormones that send messages from one cell to another cell. Some of the messages are actually a particular type of protein. What cell organelles would be involved with protein signals getting out of one cell to other endocrine cells?

Muscles cells have organelles that make 2 types of proteins that enable your muscles to work. These organelles can be found in two locations in a cell, on one of the other organelles and in the cell's cytoplasm. What organelles would you expect to be plentiful in muscle cells? What other organelle might these organelles be found on in the cell?

Onion cells are classified as plant cells, but they are not green. When looking through a microscope, an onion cell is shaped like a plant cell. What organelle is missing in onion cells if they are not green? According to this scenario, what other organelle must be present for an onion cell to be identified as a plant cell under a microscope?
