Let’s figure out the parts of a seed step by step.
We’re looking at a diagram of a seed with lines pointing to different parts, and we need to label them correctly. The word bank gives us some clues — one of the words is “epicotyl,” which is part of the embryo inside the seed.
Here’s how seeds are usually labeled:
1.
Seed coat – This is the outer protective layer. It’s like the skin of the seed. In the diagram, it’s the big oval shape surrounding everything.
2.
Cotyledon – This is the food storage part for the baby plant. In beans (which this looks like), there are two large halves that store nutrients. That’s probably the big inner part.
3.
Epicotyl – This becomes the shoot or stem and leaves of the new plant. It’s near the top of the embryo.
4.
Hypocotyl – This is the part between the epicotyl and the radicle. It helps push the cotyledons up during germination.
5.
Radicle – This is the first root that grows when the seed sprouts. It’s at the bottom tip of the embryo.
Now let’s match these to the boxes in the diagram from top to bottom:
- Top box → points to the tiny leaf-like structure → that’s the
epicotyl
- Second box → points to the curved stalk below the epicotyl → that’s the
hypocotyl
- Third box → points to the very tip at the bottom of the embryo → that’s the
radicle
- Fourth box → points to the large inner area → that’s the
cotyledon
- Bottom box → points to the outer shell → that’s the
seed coat
Wait — let’s double-check the order based on typical diagrams. Sometimes the labels go from top to bottom along the embryo, then the cotyledon, then the seed coat.
Actually, looking again:
The four boxes on the left point to:
1. Topmost small leafy part → epicotyl
2. Curved stem part below it → hypocotyl
3. Tip at the bottom → radicle
4. Large inner mass → cotyledon
Then the separate box at the bottom points to the outer covering → seed coat
Yes, that makes sense.
So final labeling from top to bottom (left side boxes):
1. Epicotyl
2. Hypocotyl
3. Radicle
4. Cotyledon
Bottom box: Seed coat
Final Answer:
Top to bottom (left boxes):
1. Epicotyl
2. Hypocotyl
3. Radicle
4. Cotyledon
Bottom box: Seed coat
