Photosynthesis Diagram Labelling - Worksheet Twinkl, 45% OFF - Free Printable

Let’s solve this step by step.

We are looking at a diagram about photosynthesis — how plants make their own food using sunlight, water, and carbon dioxide. The equation given is:

> Light + Carbon dioxide + Water = Oxygen + Glucose

That means:
- Inputs (what the plant takes in): Light, Carbon dioxide, Water
- Outputs (what the plant makes or releases): Oxygen, Glucose

Now let’s look at the arrows in the diagram:

1. Sun → Tree: This must be Sunlight (energy source).
2. Cloud with rain → Tree: Rain comes from clouds → that’s Water.
3. Arrow pointing to tree from air (left side): Plants take in Carbon dioxide from the air.
4. Arrow going out from tree to air (right side): Plants release Oxygen.
5. Arrow going down from tree to ground/roots area: This is likely where the plant stores or uses Glucose (its food).

Also, there’s a box under the roots — probably for Water, since roots absorb water from soil. But wait — we already have rain as water input. Let’s double-check.

Actually, looking again:

- Sun → Sunlight ✔
- Cloud/rain → Water ✔
- Left arrow into leaves → Carbon dioxide ✔
- Right arrow out of leaves → Oxygen ✔
- Bottom arrow from roots → maybe Water? But water comes from rain too... Hmm.

Wait — perhaps the bottom box is for Glucose? No, glucose is made inside the plant and used/stored — it doesn’t come from outside.

Let’s match each blank based on direction and logic:

Top center box (above tree) — no direct arrow, but maybe it's not needed? Actually, all boxes have arrows except top center? Wait, let’s count:

There are 6 empty boxes:

1. Top left (next to sun) → should be Sunlight
2. Top right (under cloud) → should be Water
3. Middle left (arrow into tree) → Carbon dioxide
4. Middle right (arrow out of tree) → Oxygen
5. Bottom left (arrow into roots) → could be Water again? Or maybe it’s redundant?
6. Bottom right (arrow out from base) → Glucose

But according to the word bank:
Available words: Sunlight, Oxygen, Glucose, Water, Carbon dioxide

And the equation says:
Inputs: Light, CO₂, H₂O → Outputs: O₂, Glucose

So let’s assign:

- Arrow from sun → Sunlight
- Arrow from cloud/rain → Water
- Arrow from left air → Carbon dioxide
- Arrow to right air → Oxygen
- Arrow from roots upward? Wait, actually, one arrow goes INTO roots (from below), and one goes OUT from base (to right).

Typically, roots absorb Water and minerals — so the arrow INTO roots should be Water.

Then what about the rain? Maybe the rain is also water — but perhaps the diagram shows two sources? That might be confusing.

Alternatively, maybe the rain represents water falling, and the root arrow is also water being absorbed — same thing.

But we only have one “Water” in the word bank.

Wait — let’s list the blanks with positions:

Looking at standard photosynthesis diagrams:

- Sun → provides Light energy
- Air → provides CO₂
- Soil/Rain → provides H₂O
- Plant releases O₂ into air
- Plant produces Glucose for itself

In this diagram:

Boxes:

A. Next to sun → Sunlight

B. Under cloud → Water (rain)

C. Left middle (into leaves) → Carbon dioxide

D. Right middle (out of leaves) → Oxygen

E. Bottom left (into roots) → ??? If rain is already water, maybe this is duplicate? But perhaps it’s meant to show water entering via roots — so still Water

F. Bottom right (out from base) → Glucose

But we can’t use “Water” twice if it’s only listed once in the word bank.

Wait — the word bank has five terms: Sunlight, Oxygen, Glucose, Water, Carbon dioxide — exactly matching the five components in the equation.

The diagram has six boxes? Let me recount from your image description:

You said: “Photosynthesis Cut and Paste” with:

- Sun on left
- Cloud with rain on right
- Tree in center
- Arrows:
- From sun to tree
- From cloud to tree
- From left air to tree
- From tree to right air
- From below to roots (upward arrow?)
- From base of tree to right/down (outward)

Actually, re-examining typical such worksheets:

Usually:

- Sun → Sunlight
- Cloud/Rain → Water
- Left arrow (air to leaf) → Carbon dioxide
- Right arrow (leaf to air) → Oxygen
- Roots absorbing → Water (but sometimes omitted if rain is shown)
- And then product: Glucose stored or used — often shown as arrow going to fruit or storage

In this case, the bottom right arrow is likely Glucose

And the bottom left arrow into roots — if rain is already providing water, maybe that’s redundant? But perhaps the worksheet intends:

Box 1 (sun side): Sunlight
Box 2 (cloud side): Water
Box 3 (left air): Carbon dioxide
Box 4 (right air): Oxygen
Box 5 (roots input): Water ← but we don’t have two waters
Wait — unless the rain is just illustrating weather, and the actual water uptake is through roots.

Perhaps the cloud/rain is meant to represent precipitation, which becomes soil water, taken up by roots.

So maybe:

- The arrow from cloud to tree is indirect — meaning rain falls, enters soil, then roots absorb it.

But in simple diagrams, they often put:

- Sun → Sunlight
- Air → CO₂
- Soil/Water → H₂O
- Out: O₂ and Glucose

Given that, and the word bank has exactly 5 items, and there are 5 distinct roles, I think the six boxes might include one that’s not labeled or perhaps I miscounted.

Wait — looking back at your initial problem statement: you mentioned "cut and paste" with blanks around the tree.

Standard version of this worksheet usually has 5 blanks corresponding to the 5 inputs/outputs.

Let me assume the boxes are:

1. Beside sun → Sunlight
2. Beside cloud → Water
3. Left of tree (incoming air) → Carbon dioxide
4. Right of tree (outgoing air) → Oxygen
5. Below tree (product) → Glucose

And the sixth box? Maybe it’s a mistake, or perhaps the root absorption is implied.

But in many versions, the water is shown coming from roots, not directly from rain.

To resolve this, let’s go by the equation:

Input: Light, CO₂, H₂O
Output: O₂, Glucose

So three inputs, two outputs.

In the diagram:

Arrows INTO tree:
- From sun → Light
- From left → CO₂
- From bottom/root → H₂O

Arrows OUT of tree:
- To right → O₂
- To bottom/right → Glucose

That’s five arrows → five boxes.

Probably the cloud with rain is decorative or indicates source of water, but the actual label goes on the root arrow.

So final assignment:

- Box next to sun: Sunlight
- Box next to cloud: possibly not used, or if must fill, but we have only 5 terms — wait, word bank has 5, so 5 boxes.

I think in your image, there are 5 blank rectangles to fill.

Assuming that:

Position 1 (top left, near sun): Sunlight
Position 2 (top right, under cloud): Water — but if water is absorbed by roots, maybe this is incorrect.

Alternative common layout:

- Sun → Sunlight (label on arrow or box beside sun)
- Cloud → represents atmosphere, but water comes from ground
- So better:

Label the arrows:

- Arrow from sun: Sunlight
- Arrow from air (left): Carbon dioxide
- Arrow from soil/roots: Water
- Arrow to air (right): Oxygen
- Arrow to storage (bottom): Glucose

And the cloud might just be part of the scene, not requiring a label.

Given that, and to match the word bank perfectly:

Final mapping:

1. Box associated with sun → Sunlight
2. Box associated with incoming air (left) → Carbon dioxide
3. Box associated with roots/water uptake → Water
4. Box associated with outgoing air (right) → Oxygen
5. Box associated with product/storage → Glucose

The cloud with rain may be illustrative, and the water label goes with the root absorption.

Therefore, for the cut-and-paste:

- Place "Sunlight" near the sun
- Place "Carbon dioxide" on the left arrow into leaves
- Place "Water" on the arrow into roots
- Place "Oxygen" on the arrow out to air
- Place "Glucose" on the arrow going to storage/base

This matches the equation and biology.

Final Answer:
Sunlight → near sun
Carbon dioxide → left arrow into tree
Water → arrow into roots
Oxygen → right arrow out of tree
Glucose → bottom arrow out from tree base
