FAQs on Trees Class 7 PPT
| 1. What are the different parts of a tree? |  |
Ans. A tree is composed of various parts such as roots, trunk, branches, leaves, and fruits. The roots anchor the tree in the ground and absorb water and nutrients. The trunk provides support and transports water and nutrients between the roots and the rest of the tree. The branches extend from the trunk and hold the leaves. The leaves perform photosynthesis, producing food for the tree. Fruits are the reproductive structures of the tree, containing seeds for propagation.
| 2. How do trees contribute to the environment? | |
Ans. Trees play a vital role in the environment. They absorb carbon dioxide and release oxygen through the process of photosynthesis, helping to reduce air pollution and combat climate change. Trees also provide shade, reducing the need for air conditioning and lowering energy consumption. They act as natural filters, absorbing pollutants and improving air quality. Additionally, trees help prevent soil erosion, provide habitats for wildlife, and contribute to overall biodiversity.
| 3. What are the benefits of planting trees? | |
Ans. Planting trees offers numerous benefits. Trees beautify the surroundings, enhance the aesthetic appeal of an area, and provide a sense of tranquility. They create a cooler microclimate by providing shade, reducing the temperature, and minimizing the urban heat island effect. Trees also improve water quality by reducing runoff and acting as a natural filter. They provide habitats for birds and other wildlife, support biodiversity, and can even increase property values in residential areas.
| 4. How long does it take for a tree to grow? | |
Ans. The time it takes for a tree to grow varies depending on the species, environmental conditions, and planting techniques. Generally, it takes several years for a tree to reach maturity. Some fast-growing species can grow several feet per year and reach maturity within 10-20 years. In contrast, slow-growing species may take several decades or even centuries to fully mature. It is important to consider the specific requirements of each tree species when planning for their growth and development.
| 5. How can I take care of newly planted trees? | |
Ans. Taking care of newly planted trees is crucial for their successful establishment. Here are some tips:
- Water the tree regularly, especially during the first year, ensuring that the soil remains moist but not waterlogged.
- Apply mulch around the base of the tree to help retain moisture, regulate soil temperature, and suppress weed growth.
- Prune any damaged or diseased branches to promote healthy growth.
- Protect the tree from pests and diseases by monitoring for signs of infestation and applying appropriate treatments if necessary.
- Provide support, such as staking, if the tree is weak or prone to leaning.
- Regularly monitor the tree's growth and health, addressing any issues promptly.
By following these care practices, you can increase the chances of your newly planted tree thriving and becoming a valuable asset to the environment.
