Photosynthesis - Worksheet | Printable and Distance Learning ... - Free Printable

Problem Analysis:

The task involves understanding the process of photosynthesis and labeling the components in a diagram. Photosynthesis is the process by which plants convert light energy into chemical energy, using carbon dioxide (CO₂) and water (H₂O) to produce glucose (sugar) and oxygen (O₂). The diagram provided shows a plant with arrows pointing to different substances involved in this process.

Solution:

#### Q.1: Label the blanks on the diagram below to show the overall process of photosynthesis.

To label the blanks in the diagram, we need to identify the substances involved in photosynthesis and their directions:

1. Top left blank (near the sun):
- This represents the sunlight that provides the energy for photosynthesis.
- Label: Sunlight

2. Middle left blank (near the cloud):
- This represents carbon dioxide (CO₂), which enters the plant through its leaves.
- Label: Carbon Dioxide (CO₂)

3. Bottom left blank (near the soil):
- This represents water (H₂O), which is absorbed by the plant's roots from the soil.
- Label: Water (H₂O)

4. Middle right blank (near the cloud):
- This represents oxygen (O₂), which is released as a byproduct of photosynthesis.
- Label: Oxygen (O₂)

5. Bottom right blank (near the sugar cubes):
- This represents glucose (C₆H₁₂O₆), the sugar produced during photosynthesis.
- Label: Glucose (C₆H₁₂O₆)

#### Labeled Diagram:
- Top left: Sunlight
- Middle left: Carbon Dioxide (CO₂)
- Bottom left: Water (H₂O)
- Middle right: Oxygen (O₂)
- Bottom right: Glucose (C₆H₁₂O₆)

#### Q.2: Fill in the blanks with suitable words.

Now, let's fill in the blanks based on our understanding of photosynthesis:

a) Green plants make their own food through a process known as _____________.
- The process by which green plants make their own food is called photosynthesis.
- Answer: Photosynthesis

b) Carbon dioxide enters the leaf by the way of tiny pores or openings called _____________.
- The tiny pores or openings in the leaves through which carbon dioxide enters are called stomata.
- Answer: Stomata

c) Plants gather the sun’s energy with light-absorbing pigments called _____________.
- The light-absorbing pigments in plants that capture sunlight are primarily chlorophyll.
- Answer: Chlorophyll

Final Answers:

#### Q.1 Labels:
- Top left: Sunlight
- Middle left: Carbon Dioxide (CO₂)
- Bottom left: Water (H₂O)
- Middle right: Oxygen (O₂)
- Bottom right: Glucose (C₆H₁₂O₆)

#### Q.2 Fill in the blanks:
a) Photosynthesis
b) Stomata
c) Chlorophyll

Explanation:

- Photosynthesis is the process where plants use sunlight, water, and carbon dioxide to produce glucose and oxygen.
- Stomata are the small openings in leaves that allow gases (CO₂ and O₂) to enter and exit the plant.
- Chlorophyll is the pigment in plant cells that absorbs light energy, initiating the photosynthesis process.
