Parts of a Seed Worksheets -Worksheets Library - Free Printable

The image shows a diagram of a seed, with labeled parts and two lists of terms to match the numbers (1–5) on the diagram. The goal is to correctly identify each part of the seed based on the labels.

Let’s analyze the diagram and match the correct terms:

---

🔍 Diagram Overview:

- The large outer structure is the seed coat.
- Inside, there is an embryo, which includes:
- The cotyledon(s) – the first leaves or food storage organs.
- The epicotyl – the part that will become the shoot/stem.
- The radicle – the embryonic root.
- The food storage may be in the cotyledons or a separate area.

Now let’s go through each numbered label on the diagram:

---

✔ Matching the Labels:

#### Label 1 → Points to the large, oval structure inside the seed.
- This is the embryo, but more specifically, it's the cotyledon (the seed leaf), which stores food.
- In many seeds (like beans), the cotyledon is the main food storage organ.
- So, 1 = COTYLEDON (from second list).

> ✔ 1: COTYLEDON

#### Label 2 → Points to the upper part of the embryo (the "leaf-like" structure).
- This is the first leaves (plumule), also called the epicotyl.
- The epicotyl develops into the stem and leaves.
- So, 2 = EPICOTYL.

> ✔ 2: EPICOTYL

#### Label 3 → Points to the small, pointed tip at the bottom of the embryo.
- This is the embryonic root, also known as the radicle.
- The radicle grows into the root after germination.
- So, 3 = RADICLE.

> ✔ 3: RADICLE

#### Label 4 → Points to the entire embryo structure.
- This includes the cotyledon, epicotyl, and radicle.
- So, 4 = EMBRYO.

> ✔ 4: EMBRYO

#### Label 5 → Points to the outer covering of the seed.
- This is the seed coat, which protects the embryo.
- So, 5 = SEED COAT.

> ✔ 5: SEED COAT

🧩 Final Answer:

| Number | Correct Term |
|--------|--------------------|
| 1 | COTYLEDON |
| 2 | EPICOTYL |
| 3 | RADICLE |
| 4 | EMBRYO |
| 5 | SEED COAT |

---

💡 Explanation:

- The cotyledon is the seed leaf; in dicots like beans, it stores food for the developing plant.
- The epicotyl becomes the shoot and leaves.
- The radicle becomes the root.
- The embryo is the entire developing plant inside the seed.
- The seed coat protects the seed from damage and desiccation.

This diagram represents a dicot seed, such as a bean, where the embryo has two cotyledons (though only one is shown here in cross-section).

✔ Therefore, the correct matching is using the second list:
> 1. COTYLEDON
> 2. EPICOTYL
> 3. RADICLE
> 4. EMBRYO
> 5. SEED COAT

The first list (with “FOOD STORAGE”, “FIRST LEAVES”, etc.) is less precise—while technically correct in some contexts, the second list uses standard botanical terminology and matches the diagram accurately.

✔ Answer: Use the second list of terms to label the diagram.
