Photosynthesis worksheet - Free Printable

Let’s go step by step to label each part of the plant and give its function.

We already know:
- A is a side root → Function: To hold the plant in the soil (also helps absorb water and minerals, but we’ll stick with what’s given).

Now let’s look at the other letters:

---

B – This points to the main vertical part of the plant above ground. That’s the stem.
→ Function: Supports the leaves and flowers; carries water and food between roots and leaves.

---

C – This points to one of the flat green parts on the side. That’s a leaf.
→ Function: Makes food for the plant using sunlight (photosynthesis).

---

D – This points to the flower at the top. That’s the flower.
→ Function: Helps the plant make seeds (for reproduction).

---

E – This also points to a leaf — same as C. So it’s also a leaf.
→ Function: Same as C — makes food using sunlight.

*(Note: Even though there are two leaves labeled, they’re both leaves and have the same job.)*

---

F – This points to where the stem meets the roots, just under the soil line. That’s the base of the stem or sometimes called the root-shoot junction, but more simply, it’s still part of the stem near the soil. However, looking closely, F is pointing to the area right above the roots — this is often considered the main stem base. But in many school diagrams, if it’s not clearly a different organ, and since B is already the stem, F might be intended to show the taproot or main root? Wait — no, G is pointing to a small round thing on a root.

Wait — let’s recheck:

Actually, F is pointing to the thick central root going down — that’s the taproot (main root).
→ Function: Anchors the plant and absorbs water and minerals from deep in the soil.

But wait — A is already “side root”, so F must be the main root or taproot.

Yes — that makes sense.

---

G – This points to a small swollen bit on a side root. That’s likely a root nodule (especially if this were a legume plant), but in general basic plant diagrams, this could also represent a lateral root tip or even a storage root. However, in most elementary contexts, if it’s a bump on a root, it may be meant to show a root hair zone or simply another side root branch. But since A is already “side root”, and G is a specific point on a root, perhaps it’s meant to be a root cap? No — root caps are at the very tips.

Looking again — G is pointing to a small dark oval on a side root. In some diagrams, this represents a mycorrhizal association or nodule, but for basic level, it’s probably just indicating a root tip or growing point.

However, in many standard worksheets like this, G is often used to indicate a root hair or absorbing region — but root hairs aren’t usually drawn as big ovals.

Alternatively — perhaps G is meant to be a tuber or storage organ, but it’s attached to a root.

Wait — let’s think simply.

In basic plant anatomy for schools:

- A = side root
- F = main root (taproot)
- G = possibly a root tip or zone of absorption

But actually, looking at common labeling:

Often, G in such diagrams is meant to be a root nodule (if nitrogen-fixing) or just a lateral root branching point.

But since the question says “give one function”, and we need to match standard answers...

Another possibility: G is pointing to a seed or fruit? No — it’s underground on a root.

Wait — perhaps it’s a mistake? Or maybe it’s meant to be a bulb or tuber?

No — let’s go back to basics.

Standard plant parts:

Roots: A (side root), F (main root/taproot), G (perhaps root tip or absorbing region)

But in many textbooks, when they label G like that, it’s often the root cap — which protects the growing tip.

Function of root cap: Protects the root as it grows through soil.

That fits.

So:

G = Root cap → Function: Protects the tip of the root as it pushes through soil.

But is that too advanced? Maybe.

Alternative: In some diagrams, G is simply another side root — but A is already labeled as side root.

Perhaps G is meant to be a fibrous root — but again, similar to A.

I think the safest bet for school level:

Since A is "side root", and F is the main root, then G is likely pointing to the root tip or growing point.

But let’s check online or standard answers for similar diagrams.

Actually — upon second thought, in many UK GCSE or KS3 diagrams, when you see a little bump on a root like G, it’s often meant to represent a root hair — but root hairs are tiny and numerous, not single bumps.

Wait — here’s a better idea: Perhaps G is meant to be a nodule for nitrogen fixation — but that’s specific to legumes.

Given that this is a general plant diagram, and the title is “Green plants as organisms – 1: Nutrition”, it’s likely focusing on basic structure.

Let me assign based on most logical and simple interpretation:

- B: Stem → supports plant, transports water/food
- C: Leaf → photosynthesis (makes food)
- D: Flower → reproduction (makes seeds)
- E: Leaf → same as C
- F: Taproot (main root) → anchors plant, absorbs water/minerals
- G: Root tip / root cap → protects root as it grows

But to keep it simple for student:

Perhaps G is just another root part — but since A is side root, and F is main root, G might be redundant.

Wait — looking at the diagram again mentally: G is pointing to a small rounded structure on a lateral root. In some diagrams, this is a tuber or storage root, but unlikely.

Another common label: G could be a mycorrhiza — symbiotic fungus — but again, too advanced.

I recall that in some worksheets, G is labeled as root hair zone — function: increases surface area for absorption.

That makes sense for nutrition topic.

So:

G = Root hair zone → Function: Absorbs water and minerals from soil.

Even though it's drawn as a single blob, we can interpret it as representing the region where root hairs are.

This fits the "Nutrition" theme.

So final assignments:

- A: Side root → To hold the plant in the soil (given)
- B: Stem → Supports the plant and carries water and food
- C: Leaf → Makes food using sunlight
- D: Flower → Produces seeds for new plants
- E: Leaf → Makes food using sunlight (same as C)
- F: Main root (taproot) → Anchors plant and absorbs water and minerals
- G: Root hair zone → Absorbs water and minerals from soil

Yes, this works.

Now, to write in table format.

Final Answer:

| Letter | Part of the plant | Function or job |
|--------|-----------------------|------------------------------------------|
| A | Side root | To hold the plant in the soil |
| B | Stem | Supports the plant and carries water and food |
| C | Leaf | Makes food using sunlight |
| D | Flower | Produces seeds for new plants |
| E | Leaf | Makes food using sunlight |
| F | Main root (taproot) | Anchors plant and absorbs water and minerals |
| G | Root hair zone | Absorbs water and minerals from soil |

Note: For E, since it's also a leaf, function is same as C. Some might say "transpiration" but primary function for nutrition is photosynthesis.

For G, if "root hair zone" is too technical, could say "part of root that absorbs water" — but "root hair zone" is acceptable.

Alternatively, if curriculum expects simpler terms:

G could be "root tip" → function: grows into soil to find water

But absorption is key for nutrition.

I think "root hair zone" is fine.

Some might argue G is a nodule — but without context, absorption is safer.

So I'll go with that.
