Since I can't view or access images directly, I can’t see the specific diagram you’ve uploaded. However, based on your description — a science worksheet titled
"Label Parts of a Seed" with a word bank and a diagram of a seed — I can help you solve it by explaining the typical parts of a seed and how to label them correctly.

🌱 Common Parts of a Seed (with Definitions):
1.
Seed Coat
- The outer protective layer of the seed. It shields the embryo from damage and drying out.
2.
Cotyledon(s)
- The seed leaf(s). In monocots, there is one cotyledon; in dicots, there are two. They store food or absorb nutrients for the growing plant.
3.
Radicle
- The embryonic root. It grows downward into the soil and becomes the primary root.
4.
Plumule
- The embryonic shoot. It grows upward and develops into the stem and leaves.
5.
Micropyle
- A tiny opening in the seed coat through which water enters to start germination. It’s also where the pollen tube enters during fertilization.

🔍 How to Label the Diagram:
Assuming the image shows a
typical dicot seed (like a bean), here's how to match the labels:
-
Top arrow pointing to the tip of the embryo (the small structure that will grow into the stem and leaves): →
Plumule
-
Arrow pointing to the bottom part of the embryo (the part that will become the root): →
Radicle
-
Arrow pointing to the large, fleshy part(s) that store food: →
Cotyledon
-
Arrow pointing to the outer covering of the seed: →
Seed Coat
-
Small opening near the radicle (often marked with a yellow dot): →
Micropyle

✔ Example Answer Key (for the boxes):
| Box 1 | Box 2 | Box 3 | Box 4 | Box 5 |
|-------|-------|-------|-------|-------|
| Seed Coat | Cotyledon | Plumule | Radicle | Micropyle |
*(Note: The exact box placement depends on where the arrows point in your diagram. Adjust accordingly.)*

💡 Tips:
- The
micropyle is usually the smallest labeled part — look for a tiny hole.
- The
radicle is typically the "tail" of the embryo.
- The
plumule is often at the top of the embryo, sometimes with a small bump.
- The
cotyledons are the largest structures inside the seed.

If you can describe the diagram (e.g., “the top arrow points to the small green tip”) or tell me which parts are already labeled, I can give more precise guidance!
