According to the side picture here, what parts of a crown are there?
Correct Answer
D. Leaves, branches, and twigs
Explanation
Based on the side picture, we can see that there are multiple small, green structures extending outwards from the main structure. These structures resemble leaves, while the larger structures extending upwards resemble branches. Additionally, there are smaller, thinner structures extending from the branches, which can be identified as twigs. Therefore, the correct answer is "leaves, branches, and twigs."
2.
A tree consists of three main parts: the crown or canopy, trunk and roots. The crown or canopy is at the top of a tree. It filters dust and other particles from the air. It consists of leaves, branches and twigs. As you all know, the leaves are the food factories of a tree. They contain chlorophyll which helps photosynthesis process and gives green color to the leaves. What is the function of the crown?
Correct Answer
B. To filter dust and other particles from the air
Explanation
The function of the crown is to filter dust and other particles from the air.
3.
Where is the food of a tree produced?
Correct Answer
C. Leaves
Explanation
Leaves are responsible for producing food in a tree through a process called photosynthesis. They contain chlorophyll, which captures sunlight and converts it into energy. This energy is used to convert carbon dioxide and water into glucose, a form of sugar that serves as the tree's food source. Therefore, the correct answer is leaves.
4.
What makes the green color to the leaves?
Correct Answer
A. ChloropHyll
Explanation
Chlorophyll is the pigment responsible for giving leaves their green color. It is an essential component in photosynthesis, the process by which plants convert sunlight into energy. Chlorophyll absorbs light energy from the sun and uses it to convert carbon dioxide and water into glucose and oxygen. The presence of chlorophyll in the leaves allows them to capture sunlight and carry out photosynthesis, which is crucial for the plant's growth and survival.
5.
The trunk of a tree supports the crown and gives the tree its shape and strength. The trunk consists of some layers. The layers carry water and minerals up from the roots to the leaves and they carry sugar down from the leaves, branches, trunk and roots. Which of the following sentences is not the function of a layer?
Correct Answer
C. It filters water and nutrients from the ground
Explanation
The given sentence "It filters water and nutrients from the ground" is not a function of a layer in the trunk of a tree. The trunk layers are responsible for carrying water and minerals up from the roots to the leaves and carrying sugar down from the leaves, branches, trunk, and roots. Filtering water and nutrients from the ground is typically performed by the root system of the tree, not the layers in the trunk.
6.
What is the aim of a trunk of a tree?
Correct Answer
D. To support the crown or canopy
Explanation
The aim of a trunk of a tree is to support the crown or canopy. The trunk provides structural support for the branches and leaves, allowing them to reach sunlight and carry out photosynthesis. It also helps to distribute nutrients and water from the roots to the rest of the tree. However, the main function of the trunk is to bear the weight of the crown, ensuring that the tree remains upright and stable.
7.
A tree’s roots absorb water and nutrients from the soil, store sugar and hold the tree upright in the ground. Roots also have a lot of branches. Some roots can go down more than four meters!How long can the roots go down into the ground?
Correct Answer
B. Four meters more
Explanation
The given passage states that "Some roots can go down more than four meters!" This implies that the roots can go down deeper than four meters into the ground. Therefore, the correct answer is "four meters more."
8.
Look at this picture carefully to answer the questions!What is this?
Correct Answer
D. Trunk
Explanation
The correct answer is trunk because in the picture, the main part of the tree that extends upward and supports the branches and leaves is visible. This is known as the trunk of the tree.
9.
A tree’s roots absorb water and nutrients from the soil, store sugar and hold the tree upright in the ground. Roots also have a lot of branches. Some roots can go down more than four meters!The function of the roots based on the text above is . . . .
Correct Answer
B. To absorb water and nutrients from the soil
Explanation
The function of the roots, as mentioned in the text, is to absorb water and nutrients from the soil.
10.
Based on the text from number 1 to 9, we can conclude that there are three main parts of a tree. What are they?
Correct Answer
B. Crown, Trunk and Roots
Explanation
Based on the information provided in the text, it can be concluded that there are three main parts of a tree: the crown, the trunk, and the roots. The crown refers to the upper part of the tree that contains the branches and leaves. The trunk is the central part of the tree that supports the crown and connects it to the roots. The roots are the underground part of the tree that absorbs water and nutrients from the soil and provides stability to the tree. Therefore, the correct answer is Crown, Trunk, and Roots.
