What happens to the tree leafs?
- A.
Green color completely disappears
- B.
Green color partially disappears
- C.
Nothing happens to the green color
- D.
Green color changes to pink
Correct Answer
A. Green color completely disappearsExplanation
The correct answer is that the green color completely disappears. This suggests that the leaves lose their chlorophyll, the pigment responsible for the green color, resulting in the disappearance of the green color. This could happen during the autumn season when the leaves undergo senescence and prepare to fall off the tree.Rate this question:

Which of these color can the leaf change to?
- A.
White
- B.
Black
- C.
Wenge
- D.
Violet
Correct Answer
B. BlackExplanation
Leaves can change color to black due to a process called senescence. During senescence, chlorophyll, the pigment responsible for the green color of leaves, breaks down and allows other pigments, such as anthocyanins, to become more visible. Anthocyanins can give leaves a black or dark purple color. This change in color is often seen in certain tree species during the autumn season.Rate this question:

What causes Autumn fall color?
- A.
Hemoglobin
- B.
Chlorophyll
- C.
Oxygen
- D.
Iron
Correct Answer
B. ChloropHyllExplanation
During autumn, the days become shorter and the temperature drops, causing trees to prepare for winter. As a result, chlorophyll, the pigment responsible for the green color in leaves, starts to break down. This breakdown reveals other pigments, such as carotenoids (which produce yellow and orange colors) and anthocyanins (which produce red and purple colors), giving the leaves their vibrant autumn colors. Therefore, chlorophyll is the correct answer as it is the main factor behind the color change in autumn.Rate this question:

How do plants take water from the ground?
- A.
Through their stems
- B.
Through their roots
- C.
Through photosynthesis
- D.
Through the chlorophyll
Correct Answer
B. Through their rootsExplanation
Plants take water from the ground through their roots. The roots of a plant have tiny hair-like structures called root hairs that absorb water and nutrients from the soil. These root hairs increase the surface area of the roots, allowing for more efficient absorption of water. The water is then transported through the stem to the rest of the plant, providing hydration and necessary nutrients for growth and survival.Rate this question:

Do plants make their own food?
- A.
Yes, absolutely
- B.
Yes, I think
- C.
Maybe
- D.
No
Correct Answer
A. Yes, absolutelyExplanation
Plants have the ability to produce their own food through a process called photosynthesis. They use sunlight, water, and carbon dioxide to produce glucose and oxygen. This process occurs in the chloroplasts of plant cells, specifically in the green pigment called chlorophyll. The glucose produced during photosynthesis is used as a source of energy for plant growth and development. Therefore, it is correct to say that plants make their own food.Rate this question:

Which type of trees shed their older leafs the most?
- A.
Monopodial
- B.
Flowerless
- C.
Deciduous
- D.
Evergreen
Correct Answer
D. EvergreenExplanation
Evergreen trees shed their older leaves the most. Unlike deciduous trees, which shed all of their leaves at once during a specific season, evergreen trees continuously shed their older leaves throughout the year. This shedding process allows the tree to make room for new growth and maintain healthy foliage. Therefore, evergreen trees are known for their ability to retain green leaves year-round, while shedding older leaves to make way for new ones.Rate this question:

What causes the brown color?
- A.
Oxygen and carbon dioxide
- B.
Wastes in the roots
- C.
Wastes in the leafs
- D.
Wastes in the stems
Correct Answer
C. Wastes in the leafsExplanation
The brown color is caused by wastes in the leaves. Leaves contain chlorophyll, which gives them their green color. However, when the leaves start to age or undergo stress, they produce waste products that can cause the color to change to brown. These waste products can be a result of natural processes or external factors such as disease or nutrient deficiencies. Therefore, the presence of wastes in the leaves can lead to the brown coloration.Rate this question:

What causes the red color?
- A.
Food trapped in the leaves
- B.
Wastes left in the leaves
- C.
Nothing
- D.
I don't know
Correct Answer
A. Food trapped in the leavesExplanation
The red color in leaves is caused by the presence of pigments called anthocyanins. These pigments are produced when sugars and other nutrients get trapped in the leaves. As the chlorophyll breaks down and the green color fades, the anthocyanins become more visible, resulting in the red color.Rate this question:

Where does the most intense Autumn fall color appear?
- A.
Maine
- B.
New England
- C.
Great Lakes
- D.
Mideast
Correct Answer
B. New EnglandExplanation
New England is known for having the most intense Autumn fall color. The region is characterized by its beautiful landscapes, including forests of deciduous trees that undergo vibrant color changes during the fall season. The combination of various tree species, such as maple, oak, and birch, along with favorable weather conditions, contributes to the stunning display of red, orange, and yellow foliage. This natural phenomenon attracts tourists from all over the world and makes New England a popular destination for leaf-peeping during the Autumn season.Rate this question:
