The brown spots on this fern contain spores. How are spores different from seeds?

  1. Spores are much smaller, because they do not contain stored food for the young plant.

    That is part of the answer. Most seeds contain stored food for the developing plant. Orchid seeds are an exception..
  2. Spores are a form of asexual reproduction.

    That is part of the answer. Spores contain only the genetic material from the parent plant.
  3. Spores develop into a different kind of plant from the parent.

    This is part of the answer. Ferns have alternation of generations, which means that the spores grow into a plant called a prothallia. The prothallia produces male and female sex cells, which join, and grow into another fern plant.
  4. All of the above.

    Yes! All three of the answers are correct.

I poured some water on this rock. Later that day, the water was all gone. What happened to it?

  1. It evaporated.

    Yes. When liquid water turns into water vapor, the process is called evaporation. That is what happened to the water on the rock.
  2. It sublimated.

    No. Sublimation is when a solid turns directly into a gas. Dry ice (frozen carbon dioxide) is an example of sublimation. The solid changes directly into carbon dioxide gas, without becoming a liquid.
  3. It condensed.

    No. Condensation is when a gas turns into a liquid. The drops of water that form on the outside of a glass of ice is the result of condensation.
  4. It precipitated.

    No. In weather, precipitation is when solid or liquid water falls from the clouds. Rain, snow, and sleet are examples of precipitation.

Which part of your body comes closest to serving the same function as a flower?

  1. Sensory organs

    No. Plants can sense their surrounds just as well without flowers.
  2. Reproductive organs

    Yes! Flowers are the reproductive organs of the plant. While most animals are either male or female, most flowers have both male (stamen) and female (pistil) reproductive organs. In this photograph, the male stamens are the green stalks with the yellow ends. The female pistil is the white structure just below the stamens.
  3. Digestive system

    No. Plants make their own food, so they do not need a digestive system.
  4. Skeletal system

    No. The stiff cell wall of a plant cell serves the same function as our skeleton.

I let mold grow on this stale loaf of bread. What part of the food web does the mold belong to?

  1. Producer.

    No. A producer captures energy from sunlight, and stores it as food. To do that, the organism needs to contain chlorophyll. This mold is green, but does not have chlorophyll.
  2. Primary Consumer.

    No. Primary consumers eat producers. This mold does not eat living plants.
  3. Secondary Consumer

    No. Secondary consumers eat other consumers. This mold does not eat animals.
  4. Decomposer

    Yes! Decomposers break down dead and decaying organisms. The mold is a fungus that is breaking down and decomposing the bread to get energy from it..

In the Yeast and Sugar video, I added different kinds of sugar to bottles with yeast and warm water. One of the bottles was a control. What should have been in that bottle?

  1. Just water

    No. With just water, you are removing two variables, the yeast and the sugar. You only want to remove the independent variable.
  2. Water and yeast

    Yes! A control should be exactly like the others, but without the independent variable (the variable you are changing in the experiment.) In this case, the variable you are changing is the kind of sugar, so the control should have everything except for the sugar.
  3. Water and sugar

    No. The yeast is not the independent variable, so leaving it out would not be correct.
  4. Water and salt

    No. Adding salt would be adding a new variable, which is not correct.
