Problem Description:
The image provided is a worksheet titled "Plants have needs, too!" It includes observations about plants and their requirements for growth. The worksheet also presents two questions related to an image of a garden where the owners have been on vacation for two weeks. The goal is to analyze the image and answer the questions based on plant science.
---
Key Observations from the Image:
1.
Garden Scene: There is a house with a garden in front of it.
2.
Plants Under the Tree: The grass under the tree appears less green compared to other areas.
3.
Hanging Basket: A hanging basket with flowers is visible, but the flowers appear wilted or unhealthy.
---
Questions to Answer:
1.
Why has the grass grown less under the tree than anywhere else?
2.
Why do the flowers in the hanging basket look unhealthy?
---
Solution and Explanation:
####
Question 1: Why has the grass grown less under the tree than anywhere else?
-
Reason: Plants require sunlight for photosynthesis, which is the process by which they produce their food (glucose) using sunlight, water, and carbon dioxide.
-
Observation: The area under the tree is shaded because the tree's leaves block sunlight from reaching the ground. This lack of sunlight prevents the grass from receiving enough light to perform photosynthesis efficiently.
-
Conclusion: As a result, the grass under the tree grows less vigorously compared to areas that receive full sunlight.

####
Question 2: Why do the flowers in the hanging basket look unhealthy?
-
Reason: Plants need regular watering to survive. During the two weeks the owners were on vacation, the hanging basket likely did not receive any water.
-
Observation: Flowers in hanging baskets are particularly vulnerable to drying out because the soil in the basket can dry quickly, especially if exposed to sunlight and wind.
-
Conclusion: Without water, the flowers cannot absorb nutrients from the soil, and their cells lose turgor pressure, causing them to wilt and appear unhealthy.
---
Final Answers:
1.
Why has the grass grown less under the tree than anywhere else?
Answer: The grass under the tree receives less sunlight due to shading from the tree, which limits its ability to perform photosynthesis and grow as vigorously as grass in sunlit areas.
2.
Why do the flowers in the hanging basket look unhealthy?
Answer: The flowers in the hanging basket are likely unhealthy because they have not been watered during the two weeks the owners were on vacation, leading to dehydration and wilting.
---
Boxed Final Answer:
\[
\boxed{
\text{1. Less sunlight under the tree limits photosynthesis.}
\quad
\text{2. Lack of watering caused dehydration and wilting.}
}
\]
