Q.1: Label the blanks on the diagram

We need to label what goes into and comes out of the plant during photosynthesis.

Recall the basic equation for photosynthesis:

> Carbon dioxide + Water + Sunlight → Glucose (food) + Oxygen

Now, let’s match each blank in the diagram based on arrows and position:

- Top left box (arrow from sun) → This is Sunlight or Light energy
- Middle left box (arrow from cloud toward leaf) → Clouds represent air; plants take in Carbon dioxide from air through leaves
- Bottom left box (arrow from water droplet to roots) → Roots absorb Water from soil
- Top right box (arrow going up from leaf to cloud) → Plants release Oxygen into air
- Bottom right box (arrow going down from leaf to sugar cubes) → Sugar cubes represent food made by plant → Glucose or Food/Sugar

So labeling them:

→ Top left: Sunlight
→ Middle left: Carbon dioxide
→ Bottom left: Water
→ Top right: Oxygen
→ Bottom right: Glucose (or “Food” or “Sugar”)

*(Note: In school-level diagrams, “Glucose” is often labeled as “Food” or “Sugar” — either is acceptable unless specified. We’ll use “Glucose” since it’s scientifically accurate, but “Food” also works.)*

Actually, looking at common worksheets, they often use:

- Inputs: Sunlight, Carbon Dioxide, Water
- Outputs: Oxygen, Glucose (or Food)

So we’ll go with that.

Q.2: Fill in the blanks

a) Green plants make their own food through a process known as ________________.
→ That’s photosynthesis

b) Carbon dioxide enters the leaf by the way of tiny pores or openings called ________________.
→ Those are stomata (singular: stoma)

c) Plants gather the sun’s energy with light absorbing pigments called ________________.
→ That’s chlorophyll
