Incredible Trivia Facts Quiz On Force And Motion In Plants! - Quiz

Incredible Trivia Facts Quiz on Force and Motion in Plants! The motion of the plant is dependent on different factors and forces in their environment. The major force that acts on a plant is gravitational pull. How about you take this exciting quiz, and get to see just how much you know about the growth of a plant, and how their motion changes?

Questions and Answers

1.

Geotropism is a force that affects certain organisms. This force will result in which of the following?
- A.
  
  A flower to die due to lack of water.
- B.
  
  The roots of a plant to grow upward.
- C.
  
  The stem and leaves of a plant to grow upward.
- D.
  
  The stem and leaves of a plan to grow downward.
Correct Answer
C. The stem and leaves of a plant to grow upward.

Explanation
Geotropism is a force that affects the growth of plants in response to gravity. It causes the roots of a plant to grow downward, while the stem and leaves grow upward. This is because the roots are positively geotropic, meaning they grow in the direction of gravity, while the stem and leaves are negatively geotropic, meaning they grow against gravity. Therefore, the correct answer is "The stem and leaves of a plant to grow upward."

When a seedling emerges upright from the soil, which force is it overcoming?
- A.
  
  Gravity
- B.
  
  Magnetism
- C.
  
  Repulsion
- D.
  
  Heat
Correct Answer
A. Gravity

Explanation
When a seedling emerges upright from the soil, it is overcoming the force of gravity. Gravity pulls objects towards the center of the Earth, causing them to fall downwards. In the case of a seedling, it has to push against gravity to grow upwards and emerge from the soil. This is known as positive geotropism, where plants grow against the force of gravity to reach sunlight and maximize photosynthesis.

Which organ in our bodies is most responsible for our movements?
- A.
  
  Brain
- B.
  
  Muscles
- C.
  
  Skin
- D.
  
  Heart
Correct Answer
B. Muscles

Explanation
The muscles in our bodies are responsible for our movements. They contract and relax to allow us to move our limbs, perform actions, and carry out various physical activities. Without muscles, we would be unable to walk, run, lift objects, or perform any voluntary movements. The brain sends signals to the muscles, instructing them to contract and initiate movement. Therefore, while the brain plays a crucial role in coordinating and controlling movements, it is the muscles that physically enable us to move.

Which would be an example of negative heliotropism?
- A.
  
  A plant growing away from sunlight
- B.
  
  A plant growing towards sunlight
- C.
  
  A plant growing opposite the direction of gravity
- D.
  
  A plant not growing
Correct Answer
A. A plant growing away from sunlight

Explanation
Negative heliotropism refers to the movement or growth of a plant away from sunlight. This is commonly observed in plants that prefer shade or have a negative phototropic response, where they grow in the opposite direction of the light source. Therefore, a plant growing away from sunlight is an example of negative heliotropism.

What environmental stimulus is most likely to result in a more rapid heartbeat in an animal?
- A.
  
  Decreased temperature
- B.
  
  Strong southerly winds
- C.
  
  Presense of a predator
- D.
  
  Lack of water
Correct Answer
C. Presense of a predator

Explanation
The presence of a predator is likely to result in a more rapid heartbeat in an animal. This is because the animal's fight-or-flight response is triggered when it senses danger, causing an increase in heart rate to supply more oxygen and nutrients to the muscles for a quick response. This physiological response prepares the animal to either fight the predator or flee from it, increasing its chances of survival.

6.

Which of the following is a change that the body will undergo to prepare for fight or flight in response to a stressful stimulus?
- A.
  
  Less blood to the brain
- B.
  
  Sweating Increases
- C.
  
  Heart Rate Decreases
- D.
  
  Muscles relax
Correct Answer
B. Sweating Increases

Explanation
When the body prepares for fight or flight in response to a stressful stimulus, sweating increases. This physiological response is due to the activation of the sympathetic nervous system, which releases stress hormones like adrenaline. Sweating helps regulate body temperature and is a part of the body's effort to cool down during heightened physical activity or stress.

Rate this question:
7.

An action or condition that occurs outside of an organism's body that causes the organism to respond?
- A.
  
  Internal stimuli
- B.
  
  External stimuli
- C.
  
  Internal response
- D.
  
  External response
Correct Answer
B. External stimuli

Explanation
External stimuli refers to any action or condition that occurs outside of an organism's body and elicits a response from the organism. This can include things like changes in temperature, light, sound, or touch. When an organism is exposed to these external stimuli, it reacts or responds in order to adapt or survive in its environment. Internal stimuli, on the other hand, are signals or changes that occur within an organism's body and can also trigger a response, but in this case, the question specifically asks for stimuli that occur outside of the body.
