Let's solve the task step by step.
Task:
Label the parts of a seed using the given terms:
cotyledon,
embryo, and
seed coat.
---
Step 1: Understand the diagram
The image shows a cross-section of a seed (likely a dicot, such as a bean), split into two halves. There are three labeled lines pointing to different parts:
1. The
outer layer of the seed.
2. The
large green structures inside the seed.
3. The
small developing plant structure in the center.
---
Step 2: Match each part with the correct term
#### 1.
Seed Coat
- This is the
outer protective layer of the seed.
- It surrounds the entire seed and protects the inner parts.
- In the diagram, this is the
dark outer boundary of the seed.
- So, the
leftmost label box (pointing to the outer layer) should be labeled:
seed coat
#### 2.
Cotyledon
- These are the
large, fleshy parts inside the seed that store food for the growing embryo.
- In a dicot seed, there are usually
two cotyledons.
- In the diagram, these are the
two large green sections on either side of the embryo.
- So, the
rightmost label box (pointing to one of the large green parts) should be labeled:
cotyledon
#### 3.
Embryo
- This is the
tiny developing plant inside the seed.
- It includes the future stem, root, and leaves.
- In the diagram, it’s the
small green structure in the center, showing a tiny leaf and stem-like part.
- So, the
middle label box (pointing to the small central structure) should be labeled:
embryo
---
Final Answer:
From
left to right, the labels should be:
1.
seed coat
2.
embryo
3.
cotyledon
---
Summary:
-
Seed coat: Outer protective layer
-
Cotyledon: Food-storing part (one or two in dicots)
-
Embryo: The young plant that will grow when the seed germinates
✔ Correct labeling:
- Left box:
seed coat
- Middle box:
embryo
- Right box:
cotyledon
This completes the worksheet!
