Quiz about Internal and External Plant Systems

Question 1

Frank was out of town for a few days and when he returned, he noticed that his plant was very wilted. He watered the plant and put it in the sun. A few hours later, he noticed that it the leaves on the plant had perked up and looked fine again. The image shows the plants before and after the water and exposure to sunlight.

Why did this occur?

Accepted Answer

The plants needed the water so the cells could expand and keep the plant upright.

Answer

The plants needed the water to help the leaves undergo photosynthesis.

Answer

The plants needed to be put in the sun so the sunlight could attract the plant.

Answer

The plants needed to be outside so it could be affected by the gravity of the Earth.

Question 2

Billy orders a plant for his garden. When it was delivered, the roots and the plant stem were not growing straight out of the clay pot. Instead, the direction of their growth was in a 'sideways' direction. The diagram shows the direction the plant was growing when it was received by Billy.

Why is the most likely reason for the direction of the plant growth?

Accepted Answer

The plant was laid on it's side inside the package and geotropism caused the plant to change it's growth direction.

Answer

The plant lost turgor pressure and changed it's growth direction.

Answer

The plant found light through the sealed package and phototropism caused the plant to change it's direction of growth.

Answer

Plants normally grow in strange patterns until they reach a certain age.

Question 3

Which of these best completes the concept map?

Accepted Answer

gravity

Answer

calcium

Answer

friction

Answer

chemical imbalance

Question 4

If the top portion of plants grow "up," explain why a small tree on a hillside does not grow straight out from the hillside?

Accepted Answer

The tree's roots and trunk are growing in response to gravity.

Answer

The tree is growing toward water.

Answer

The tree is resting on the hillside.

Answer

The tree is leaning toward the top of the hill so rain won't wash it off.

Question 5

The diagram illustrates a seed germinating. Many forces, including responses to moisture, temperature, and gravity are at work in this process. Which part of the seedling is demonstrating a negative response to gravity and which is showing a positive response to gravity?

Accepted Answer

I is negative and III is positive.

Answer

IV is negative and II is positive.

Answer

II is negative and III is positive

Answer

III is negative and IV is positive.

Question 6

he diagram illustrates a seed germinating. Many forces, including responses to moisture, light, temperature, and gravity are at work in this process.

Which of the following correctly describes two of the seedling's responses to stimuli?

Accepted Answer

I is negative to light, and III is positive to gravity.

Answer

IV is negative to temperature, and II is negative to gravity.

Answer

II is negative to light, and III is positive to gravity.

Answer

II is positive to gravity, and IV is positive to moisture.

Question 7

Scientists on a space shuttle mission studying plant growth would probably see that the plants on the space shuttle do not grow in the same direction and pattern as those on Earth. Scientists working in space would MOST LIKELY be studying the effects of which of the following stimuli on plant growth?

Accepted Answer

gravity

Answer

oxygen

Answer

radiation

Answer

temperature

Question 8

The diagram illustrates a seed germinating. Many forces, including responses to moisture, temperature, and gravity, are at work in this process. Which part of the seedling demonstrates a negative response to gravity?

Accepted Answer

III

Answer

I

Answer

II

Answer

IV

Question 9

The tip of a plant's root is covered by a root cap. The root cap produces a slimy, slippery substance. Which of the following is the MOST likely purpose for this substance?

Accepted Answer

helping roots grow through the soil

Answer

absorbing water and nutrients in soil

Answer

reducing the plant's need for soil

Answer

anchoring the plant to the soil

Question 10

The roots of the plant in the diagram above are exhibiting which behavior?

Accepted Answer

Geotropism

Answer

Autotropism

Answer

Hydrotropism

Answer

Phototropism

Question 11

Kinesiology studies how the body initiates and controls movement, beginning with the brain and using interactions of different body systems. The body moves when internal and external forces act on it. Internal forces are generated within the body, while external forces are generated outside of the body.

Internally, muscles generate force as they contract and bones generate movement. Which statement accurately represents how forces affect motion in organisms?

Accepted Answer

When a muscle contracts, it applies a pulling force on a bone, which causes movement.

Answer

When a muscle relaxes, it applies a pulling force on a bone, causing it to move.

Answer

When a bone relaxes, it applies a pushing force on a muscle, causing it to move.

Answer

When a bone contracts, it applies a pushing force on a muscle, which causes movement.

Question 12

Surrounding the lungs are sets of muscles that are able to cause air to be inhaled or exhaled from the lungs. The main muscle of respiration in humans is the diaphragm. The primary role of the respiratory system is to supply red blood cells with oxygen and remove carbon dioxide waste from the body.Which of the following statements best describe the internal relationship of force and motion concerning inhalation and exhalation in the respiratory system?

Accepted Answer

Statements 1 and 4

Answer

Statements 1 and 3

Answer

Statements 2 and 3

Answer

Statements 2 and 4

Question 13

The digestive tract contains hollow organs with a layer of muscle that enables their walls to move through a process known as peristalsis. Peristalsis looks like a wave traveling through the muscle. As muscles contract, it creates a narrowing and then propels the narrowed portion forward down the length of the organ. Each wave of narrowing continues to push materials in front of them throughout the digestive organs.

Which of the following statements best demonstrates that forces affect motion in organisms?

Accepted Answer

Statements 1, 2, 3, and 4

Answer

Statements 1 and 2

Answer

Statements 1 and 3

Answer

Statements 1, 3, and 4

Question 14

What caused the behavior of the plant in the diagram above?

Accepted Answer

Lack of turgor pressure

Answer

Response to gravity

Answer

Negative homeostasis

Answer

Excessive humidity

Question 15

The pictures above show a gerbera daisy that has experienced a change called wilting. Which of the statements below best describes what has happened from Picture A to Picture B?

Accepted Answer

Lack of water in the soil decreased the turgor pressure in the cells of the flower.

Answer

Water entering the plant increased the turgor pressure in the cells of the flower.

Answer

Water entering and leaving the cells of the flower at equal rates kept turgor pressure equal.

Answer

Lack of sunlight on a cloudy day caused the flower to lose turgor pressure.

Question 16

The picture below shows a seed germinating and growing into a young plant. Many forces are at work in the process of forming a seedling. The roots of the seedling grow downward into the soil, and the stem of the seedling grows upward above the soil.
