Questions and Answers

1.

Why are the leaves of a plant so important?
- A.
  
  They create shade for the grass.
- B.
  
  They make the food for the plant.
- C.
  
  They make green pigment from chlorophyll.
- D.
  
  They provide food for herbivores.
Correct Answer
B. They make the food for the plant.

Explanation
The leaves of a plant are important because they are responsible for photosynthesis, the process by which plants convert sunlight into energy. Through photosynthesis, leaves produce glucose, which is the plant's source of food and energy. This glucose is then transported to other parts of the plant for growth and development. Therefore, the statement "They make the food for the plant" accurately explains the importance of leaves in providing nutrition for the plant's survival.

2.

What does a plant take in from the air?
- A.
  
  Carbon Dioxide
- B.
  
  Oxygen
- C.
  
  Water
Correct Answer
A. Carbon Dioxide

Explanation
Plants take in carbon dioxide from the air through tiny openings called stomata on their leaves. This process, known as photosynthesis, allows plants to convert carbon dioxide into glucose, a form of sugar that they use for energy and growth. Oxygen is produced as a byproduct of photosynthesis and is released back into the air. Water is primarily absorbed by plants through their roots from the soil, rather than directly from the air.

3.

A plant will starve if it looses all its leaves.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Plants rely on their leaves to carry out photosynthesis, the process by which they convert sunlight into energy. Without leaves, plants are unable to produce the necessary nutrients and energy to survive, leading to starvation. Therefore, it is true that a plant will starve if it loses all its leaves.

Rate this question:
4.

_______________ open and close, allowing carbon dioxide in and oxygen out of the leaves.

Correct Answer
Stomata

Explanation
Stomata are small openings on the surface of leaves that allow for gas exchange. They open to let carbon dioxide in, which is needed for photosynthesis, and they close to prevent excessive water loss. This process allows oxygen, a byproduct of photosynthesis, to be released from the leaves. Stomata play a crucial role in regulating the exchange of gases and maintaining the balance of water in plants.

What happens when one ingredient in photosynthesis is removed?
- A.
  
  The sugar production is cut in half.
- B.
  
  The tree has stunted growth.
- C.
  
  The tree will "sleep" until it is added back.
- D.
  
  Photosynthesis can't happen at all.
Correct Answer
D. pHotosynthesis can't happen at all.

Explanation
When one ingredient in photosynthesis is removed, the process cannot occur at all. Photosynthesis requires several key components, including sunlight, water, and carbon dioxide, to produce glucose and oxygen. Without any one of these ingredients, the process cannot take place, resulting in the complete inability to perform photosynthesis. Therefore, the correct answer is that photosynthesis can't happen at all.

Rate this question:
6.

A __________ leaf has one leaf attached to the stem of a plant, while a _________________ leaf has several leaflets attached to a single petiole. (type answers in order found in sentence, put one space between answers)

Correct Answer
simple compound

Explanation
A simple leaf has one leaf attached to the stem of a plant, while a compound leaf has several leaflets attached to a single petiole.

7.

The pattern of veins on a leaf are called veination.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
The statement is true because the pattern of veins found on a leaf is indeed called veination. Veination refers to the arrangement and distribution of veins within a leaf, which can vary in different plant species. These veins play a crucial role in transporting water, nutrients, and sugars throughout the leaf, enabling photosynthesis and supporting the overall functioning of the plant.

Rate this question:
8.

Why do plants lose their leaves in the winter?
- A.
  
  The leaves would freeze.
- B.
  
  To stop transpiration.
- C.
  
  There is not enough rain in the winter.
- D.
  
  There is enough water in the ground in the winter.
Correct Answer
B. To stop transpiration.

Explanation
Plants lose their leaves in the winter to stop transpiration. Transpiration is the process by which water is lost from the leaves through tiny openings called stomata. In the winter, the cold temperatures and reduced sunlight make it difficult for plants to absorb water from the soil. By shedding their leaves, plants can conserve water and reduce the risk of desiccation. Additionally, the absence of leaves helps plants to minimize water loss and protect themselves from freezing temperatures.
