Educational worksheet on seed germination and plant growth for elementary students.

Explanation:
Let’s solve this step by step.

Part 1: Matching Column A with Column B

We match each term to its correct definition:

1. Seed → A seed is the whole structure that can grow into a new plant. But look at the options:
- D says: *Part of a plant that can grow into a new plant* — that fits “seed” well.
- E says: *Part of a seed that grows into a new plant* — that’s more specific (like the embryo).
So Seed → D

2. Embryo → This is the tiny baby plant inside the seed. It’s the part that actually becomes the new plant.
- E says: *Part of a seed that grows into a new plant* → That’s the embryo.
So Embryo → E

3. Seed coat → This is the hard outer layer protecting the seed.
- A says: *The outer cover that protects the seed* → Perfect.
So Seed coat → A

4. Germinate → This means when a seed starts to grow (sprout).
- B says: *When the seed starts to grow* → Yes.
So Germinate → B

5. Environment → Everything around us (light, water, temperature, soil, etc.).
- C says: *Everything around us* → Correct.
So Environment → C

✔ Matches:
1–D, 2–E, 3–A, 4–B, 5–C

Part 2: Complete the sentences

Word bank:
food store, factor, air, shoot, root, swells, warmth, up, down, absorbs

Let’s fill in one by one using science knowledge:

> When a seed starts to germinate it ________ water and ________.

- First, a seed absorbs water → it takes in water.
- Then it swells (gets bigger due to water uptake).
So: absorbs, swells

> The seed gets energy from its ________.

- Inside the seed, there’s stored food (e.g., in cotyledons or endosperm) called the food store.
So: food store

> The ________ is the first part of the new plant that starts to grow. It grows ________.

- The root comes out first (to anchor and absorb water), and it grows down (toward gravity).
So: root, down

> The ________ grows next. It grows ________.

- After the root, the shoot (stem + leaves) grows upward toward light.
So: shoot, up

> Seed need water, ________ and ________ to germinate.

- Seeds need: water, air (oxygen for respiration), and warmth (right temperature).
(Note: “factor” is too vague; the three key needs are water, air, warmth.)
So: air, warmth

Let’s double-check all blanks:

1. absorbs, swells
2. food store
3. root, down
4. shoot, up
5. air, warmth

All words used? Let’s check word bank:
- food store ✔
- factor ✘ (not used — okay, not all words must be used)
- air ✔
- shoot ✔
- root ✔
- swells ✔
- warmth ✔
- up ✔
- down ✔
- absorbs ✔

“factor” is extra — fine.

Final Answer:
1–D, 2–E, 3–A, 4–B, 5–C
When a seed starts to germinate it absorbs water and swells.
The seed gets energy from its food store.
The root is the first part of the new plant that starts to grow. It grows down.
The shoot grows next. It grows up.
Seed need water, air and warmth to germinate.
