Problem Analysis:
The task involves labeling the parts of a seed and filling in blanks related to the functions of these parts. The provided terms are:
seed coat, embryo, root, leaves, food.
Step-by-Step Solution:
####
1. Labeling the Parts of the Seed:
The diagram shows a typical seed structure. Here is how each part should be labeled:
-
Seed Coat: This is the outer protective layer of the seed. It is the hard, outer covering.
-
Label: Top left box (pointing to the outer brown layer).
-
Embryo: This is the young plant inside the seed. It consists of the root and shoot (leaves).
-
Label: Middle box (pointing to the green structures inside the seed).
-
Root: This is the part of the embryo that will grow downward into the soil to absorb water and nutrients.
-
Label: Bottom left box (pointing to the lower part of the green structure).
-
Leaves: These are the parts of the embryo that will grow upward and become the first leaves of the plant.
-
Label: Top right box (pointing to the upper part of the green structure).
-
Food (Endosperm or Cotyledon): This is the storage tissue that provides nourishment for the growing embryo.
-
Label: Rightmost box (pointing to the large yellowish area).

2. Filling in the Blanks:
Now, let's fill in the blanks based on the labeled parts and their functions:
1.
A _______ protects the seed.
- The
seed coat is the outer protective layer of the seed.
-
Answer: seed coat
2.
The _______ is the baby plant. It has a _______ which will grow down. The _______ will grow up.
- The
embryo is the baby plant.
- The
root grows downward into the soil.
- The
leaves grow upward to capture sunlight.
-
Answer: embryo, root, leaves
3.
The seed has stored _______ that the baby plant will use to grow.
- The
food (stored in the endosperm or cotyledons) provides nourishment for the growing embryo.
-
Answer: food
Final Answer:
####
Labels:
- Top left:
seed coat
- Middle:
embryo
- Bottom left:
root
- Top right:
leaves
- Rightmost:
food
####
Blanks:
1. A
seed coat protects the seed.
2. The
embryo is the baby plant. It has a
root which will grow down. The
leaves will grow up.
3. The seed has stored
food that the baby plant will use to grow.
Boxed Final Answer:
\[
\boxed{
\text{seed coat, embryo, root, leaves, food}
}
\]
