These cells DO NOT have a cell wall. What does that tell us?

  1. These are young cells.

    No. Even new cells can have a cell wall.
  2. These are NOT plant cells.

    Yes! Plant cells are surrounded by a cell wall, which provides structure and protection.
  3. These are NOT animal cells.

    No. Animal cells do not have a cell wall.
  4. These are dead cells.

    No. Being alive or dead does not change whether a cell has a cell wall or not.

The "strings" in a stalk of celery are made up of xylem and phloem. Which part of your body comes closest to serving the same function?

  1. Skeleton

    No. Your skeleton provides support and protection. In plants, the cell wall provides support and protection.
  2. Intestines

    No. Your intestines allow you to absorb nutrients from your food. Plants make their own food, so they do not need a digestive system.
  3. Nerves

    No. Your nerves carry signals to let the parts of your body communicate. They carry messages for your senses, to move your muscles, etc. Instead of having nerves, plants release chemicals that signal other parts of the plant.
  4. Blood Vessels

    Yes! Your blood vessels carry water and nutrients to different parts of your body. In plants, the xylem is made up of tubes that carry water and some nutrients from the roots upwards to other parts of the plant. The phloem is made up of tubes that carry the sugar produce by photosynthesis to other parts of the plant. While they work in very different ways, your blood vessels serve basically the same function (carrying water and nutrients) as the xylem and phloem in plants.

This is a simple chart showing how energy flows through some of the parts of a food web. For example, the arrow from the grass to the grasshopper shows that the grasshopper gets it energy by eating the grass.

The hawk gets its energy by eating the water snake, but there is no arrow leading from the hawk. What should the arrow from the hawk point to>

  1. Egret

    No. The egret does not eat hawks.
  2. Carrion

    Yes! Carrion is dead animals. When the hawk eventually dies, flies will get their energy by eating the dead body. You could also draw arrows from all of the other animals to carrion.
  3. The Sun

    No. The Sun is not on the chart, and The Sun does not get its energy from the hawk.
  4. There should not be an arrow leading from the hawk.

    No. Energy cannot be destroyed. It always goes back into the system.

These layers have not been overturned or folded. Based on that, which layer is the oldest?

  1. A

    No. A is on top, which means the other layers had to be there before it could be deposited. A is younger than B and C.
  2. B

    No. By the law of Superposition, layer C had to be in place before B could form on top of it. Layer B is older than A, but younger than C.
  3. C

    Yes! As the bottom layer, the Law of Superposition tells us that it is older than layers A and B. This layer had to be in place before A and B could form on top of it..
  4. D

    No. Layer D is actually a pile of rock fragments, mostly from layer A. These fragments are the result of weathering and erosion of layers A, B, and C. D is the youngest deposit at this location.

  3. Natural Gas

    No. Natural Gas is a fossil fuel, and takes millions of years to form.
  4. Fuel Oil

    No. Fuel oil comes from petroleum, which requires extremely long periods of time to form.
