Cape Sundew Plant Mechanisms and Applications

Scientists are drawing inspiration from plant movements to design prosthetic hands. Unlike animals, plants move without muscles or brains, responding to external stimuli like light or touch. The carnivorous cape sundew plant, for example, uses pressure changes in its cells to curl its leaves and trap insects. Understanding these mechanisms can enhance soft robotics, allowing prosthetic hands to handle delicate objects with precision.

What is a key difference between plant and animal movement?

• Plants move using internal electrical signals.

• Plants rely on external stimuli for movement.

• Plants have brains that control their movement.

• Plants use muscles to move.

How does the cape sundew plant trap insects?

• By emitting a sticky web.

• By releasing a toxic gas.

• By using sharp thorns.

• By increasing cell pressure to curl its leaves.

What happens when an insect touches the tentacle of a cape sundew plant?

• The plant increases pressure inside its cells.

• The plant's tentacle changes color.

• The plant emits a loud sound.

• The plant releases a sweet nectar.

Which of the following is an application of the cape sundew plant's mechanism in technology?

• Creating faster vehicles.

• Developing stronger building materials.

• Designing soft robotic hands.

• Improving solar panel efficiency.

What is a potential benefit of using plant-inspired mechanisms in prosthetics?

• They increase the weight of prosthetics.

• They make prosthetics more rigid.

• They allow prosthetics to handle delicate objects better.

• They can make prosthetics more colorful.
