This is Kalanchoe daigremontiana, also known as Devil's Backbone or Mother of Thousands. Each of the tiny bumps on its leaves is a developing, new plant. When they are mature enough, they will separate from the parent plant, fall to the ground, and take root. This plant reproduces both asexually with its leaves, and sexually with its flowers. What is the advantage of sexual reproduction?

  1. Sexual reproduction is faster.

    No. Asexual reproduction using its leaves is actually faster than sexual reproduction, and allows the plant to produce more offspring.
  2. Sexual reproduction lets the plant produce more offspring.

    No. This plant produces more offspring by asexual reproduction than it does by seeds.
  3. Sexual reproduction prevents the plant from passing on harmful mutations.

    No. Both sexual and asexual reproduction can pass a mutation on to the offspring.
  4. Sexual reproduction gives the offspring genes from both parents.

    Yes! The main advantage of sexual reproduction is that the offspring gets half of its genetic material from each parent. This plant can reproduce asexually by producing the new, tiny plants on its leaves, but they are genetically the same as the parent. A disease or parasite which was fatal to one would be fatal to all. When it reproduces by flowers and seeds, half of the genetic material comes from the plant, and half comes from the pollen that fertilized seed. This produces offspring that have genetic variations, giving them a better chance of surviving. The survivors can then reproduce asexually to produce thousands of new plants with those traits.

Incandescent light bulbs use electrical energy to produce light energy, but it is not a direct transformation. Instead, the electrical energy is changed to a different form of energy, and then to light.

Electricity → ? → Light


What form of energy does the "?" represent?

  1. Sound

    No. Electrical energy can be transformed into sound energy, but that would not cause the bulb to light.
  2. Thermal

    Yes. As electrical energy flows through the filament, resistance changes the electrical energy into thermal energy. When the filament gets hot enough, some of the thermal energy is converted into light.
  3. Radiation

    No. The electrical energy is not transformed into radiation.
  4. Friction

    No. The electrical energy is not transformed into friction.

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.

  1. A physical change

    Partly right. Some of the changes involved in baking a cake are physical changes.
  2. A chemical change

    Partly right. Some of the changes involved in baking a cake are chemical changes.
  3. Both

    Yes! The process of baking a cake involves many changes. Some, such as water evaporating and sugar melting are physical changes. Others, such as baking powder reacting cause a change in the chemical formulas, indicating a chemical change. For more on this, read Changing How We Look at Changing
  4. Neither

    No. There are many changes involved in baking a cake.
